Hair loss is definitely something to sit up and take notice of!
Some thinning is pretty normal with age (reduced circulation and hormone production can lead to thinner hair), but if things start to shift toward visible thinning or actual baldness, you’d do well to start taking steps to counteract the problem.
One of the best preventative measures available today are laser hair growth devices. Simply put, these devices use low-level laser therapy (LLLT) to stimulate your scalp and hair follicles, encouraging hair growth. We’ll get more into them in great detail below, but for now, it’s enough to know that they (mostly) work!
There are a lot of devices to choose from, in more styles and designs than you might have realized. Don’t worry, we did the research and testing to make sure you only saw the absolute best of the best laser hair growth devices on the market.
Read over the list below, then check out our informational section to learn everything you need to know about these baldness-preventing lifesavers:
At the top of our list is the Kiierr hair growth cap, an “industry-leader” Kiierr LLLT laser caps are clinically proven & FDA Cleared to combat hair thinning, baldness, and alopecia.
What’s interesting about this hair growth device is that it looks like a baseball cap instead of having the helmet design that we’ve seen in other laser hair growth devices. This means that you can wear it with greater ease without worrying that it gives your secret away.
This laser cap applies low-level lasers to the surface of the skin. It’s a cold laser, meaning that it doesn’t produce heat so it won’t be invasive or painful. This cap enhances cellular respiration while stimulating the hair follicles via low-level light therapy (LLLT). How it works is that it stimulates the scalp’s skin so that blood flow is increased to the scalp tissue to encourage hair growth.
It comes with an automatic timer so that the cap will turn off when the treatment is complete, so you don’t have to worry about timing the process. The device beeps every 10 minutes during the treatment so you can know exactly how much longer you have to go. It makes use of medical-grade laser diodes, and 272 diodes will be activated during the treatment.
It’s both lightweight and portable, so you’ll be able to take it with you wherever you go. You have to use this laser cap for half an hour every second day to ensure that you can benefit from the treatment. If you’re currently using other hair loss methods, these can be used in conjunction with the Kiierr cap without any concerns.
Some people have reported that the battery life of this laser device isn’t that good. This can make it less user-friendly.
Pros
Low-level light therapy stimulation
Cold laser meaning it won’t be invasive or painful
Here’s another great cap: iRestore hair growth device, with 282 built-in LED and laser lights (totaling 1410 mW of power output) to combat hair thinning, baldness, and alopecia. The low-level laser light therapy is intended to deliver results in 3-6 months (including a 6-month full refund guarantee if you’re not satisfied), with a design that covers more scalp area than any other device on our list.
The “advanced” laser and red light technology uses a wavelength optimal for penetrating both your hair follicles and scalp, which delivers results up to 43% of visible improvement in hair thickness. It’s perfect for use 2-3 times a week. Thanks to its hands-free design (you just wear it like a hat!), you can enjoy the treatment while watching TV, reading a book, or even sitting at the dinner table.
Note: For best results, it’s recommended to combine this laser hair growth device with other treatments (including thinning hair shampoo, minoxidil, finasteride, or hair growth serums).
It’s not the cheapest on our list, but it’s certainly user-friendly. If, for any reason, you need to pause the treatment, you can. The device has a timer display that enables you to start, pause, and resume the treatment. The medical-grade padding makes it incredibly comfortable to wear.
Pros
For alopecia, pattern baldness, thinning hair, and a receding hairline
Built into the Theradome PRO LH80 Laser Hair Growth Helmet are 80 high-energy density lasers that stimulate your hair follicles, increasing the production of keratin and encouraging better hair growth and regrowth. It combines red light and cold lasers to penetrate deep into your scalp. Like most of the other devices on our list, it maintains the hair growth cycle, helping to push your hair from “resting” phase into “growth” phase.
The wearable device is ideal for hands-free use—slide it onto your head and let the light work while you go about your daily tasks. It’s lightweight, safe, and painless to use. It’s also wireless (unlike our top pick) and comes with a built-in rechargeable power pack that offers surprisingly good battery life.
For the best results, it’s recommended to use it for roughly 20 minutes per session, with 2-3 sessions per week. You may start seeing noticeable slowdown of hair loss in as little as four weeks, though the real effects will take longer to set in fully—2-4 months for hair thickening, and 5 months for regrowth.
Some people have reported quality issues, such as that the device breaks easily. One of the parts that people have said gets damaged is the power button, so that’s something to be aware of when handling this device. There are also issues that have been reported with the battery life of the device, which is said to run out quickly.
Pros
180-day Full Refund Policy
Developed by NASA engineers
Completely portable, while being wireless
Scalp penetration up to 5mm for follicle stimulation
This baseball cap-style hair growth device utilizes 272 diode lasers to encourage hair growth. It’s suited for both men and women, with a discreet design that will allow you to undergo treatment anytime, anywhere, without anyone noticing.
Ideally, you’ll start to see results within 12-24 weeks, and it’s effect for pale to light brown skin. With 30-minute sessions administered just 3 times a week, you’ll find it’s easy to incorporate treatment into your daily life.
The hat is perfectly safe and painless, with infrared-sensing technology that will switch off the laser lights moment you take off the hat (and shut the cap down 10 minutes later). The built-in rechargeable power pack offers convenience (no cord or cable to get tangled!) and surprisingly good battery life.
Some people who have purchased this laser cap have said that their hair is less greasy as a result of regularly using this device. This laser cap is portable and comes with a bag included for increased convenience when travelling. It’s a bit more affordable than other laser caps on the market, and comes with a 1-year warranty to back up its quality.
Pros
Lasers distributed for hard-to-reach areas
Three 30 minutes treatments per week to reap the benefits
Improve the quality and growth within 12 to 24 weeks
This is another cap-style hair regrowth device that shares a lot of similarities with the others on our list. The biggest difference between the Hairmax and its competitors, however, is that it delivers quantifiable results. That’s right: you can expect hair regrowth of an average of 129 new hairs per square inch with just three 30-minute treatments a week.
The built-in BioLights focus the laser light to optimize light energy flow to hair follicles, and it utilizes FDA-cleared treatment for hereditary hair loss and male and female pattern baldness.
The cap is sized for those with heads under 22.5 inches in circumference, making it one-size-fits-almost-all. The integrated battery pack comes with overcharge and overheat protection, and it’s lightweight enough that you’ll feel almost like you’re wearing a regular baseball cap. The insert is flexible and designed for maximum comfort during your treatment, though some reviewers found it a bit uncomfortable.
Pros
Expect to grow 129 additional hairs per square inch
FDA-cleared treatment
Use it for half an hour three times a week
Bio-Light comfort design
Cons
Isn’t suitable for heads larger than 22.5 inches
Reviews says it isn’t very comfortable and doesn’t fit well
While many of the other hair regrowth devices on our list call for longer treatments a few times per week, the Capillis Ultra cap settles for a 6-minute daily session that delivers the same results but with far less time invested. You can get through your treatment in the time it takes you to eat your meal or drink a cup of coffee, and you’re off to work, the gym, or bed without having to dedicate a full 20-30 minutes to the session.
The device is ISO13485 certified, assembled in the USA, and safe for daily use. It will even auto-shut-off after the six-minute treatment, a sign that it’s time to get up and get going on with your day.
It comes with extra accessories, such as a firm shell case with a handle, four types of plugs for use in different regions, and a shoulder strap. The cap has a flexible fit so that you can feel comfortable when using it while doing other activities. If you don’t want to use the supplied cap, you can place the laser fixture in any cap you want to wear. This makes it versatile and convenient.
Some people have complained of sizing issues with this cap, as it doesn’t fit snugly over their heads. Others have noted that the cap feels more like a hard hat than a soft, flexible cap you can wear while doing other activities.
The HairMax Hair Growth Laser Band avoids the standard helmet/cap design, and instead goes for a sleeker, smaller band shape that you simply adjust on your head according to the bald spots or patches of thinning hair you want to treat. The 82 therapeutic lasers (1230 mW output) delivers a steady current of light energy to your scalp, encouraging better follicle health and hair growth (or regrowth).
What’s amazing about this hair growth device is that each treatment lasts just 90 seconds per section. It divides your head into three sections that you treat one after the other, giving you a full treatment in less than 5 minutes. Do this three times a week, and you can expect to see results within 3-6 months.
The band uses “soft touch teeth” that makes it very comfortable to wear, and which keeps it securely in place on your head in all three positions.
This device is portable, so you can use it anywhere. This makes it ideal for travelling. It comes with a charging cradle that you can use as a stand. This makes it convenient, especially when travelling. In the pack you will also receive a power cord, user manual, and rechargeable battery.
Some people who have purchased this device have said that it is a bit heavy. It weighs about 9oz. Also, if the device fits too loosely on your head, you will have to buy replacement teeth.
Pros
Therapeutic lasers to reach the scalp effectively
Band design ensures greater comfort during use
90 seconds of use for three times a week
82 medical-grade lasers to provide full scalp coverage
Cons
If fits too loosely, you will have to buy replacement teeth
This HairMax laser growth device takes the innovative form of a comb! While that makes it user-friendly, it also means you have better control over where you want to stimulate hair growth. All you have do to is apply the comb to the bald or thinning spots, and let the lasers do their work of stimulating the follicles!
How this product works is that it delivers collimated light. This is light that moves in a straight line so it can penetrate the scalp. The laser diodes are placed closely together so that you can achieve a delivery of energy light to every area of your scalp to encourage fuller, thicker hair. It also has a patented hair-parting teeth mechanism. These teeth separate the hair so that you can get the laser energy right into the hair follicles.
Treatment time is 11 minutes, and sessions should be performed three times per week for best results. Clinical studies proved that within six months, average hair count increased by 129 hairs per square inch for every area of the scalp treated.
The comb is lightweight, easy to maneuver around your scalp, and built with a comfortable grip. It comes with a charging stand and rechargeable battery (with decent battery life). The 2-year warranty is HairMax’s guarantee that you get a quality product that delivers the results you want.
People who have purchased this laser hair growth device have reported that the instructions state it’s not suitable for dark skin tones. Others have reported experiencing a lot of shedding. While some shedding is normal, if it continues or worsens you should consult with a doctor.
Pros
Encourage the growth of 129 new hairs per square inch
Glemme doubles down on the effectiveness of its laser hair growth brush by combining it with a hair regrowth serum. The serum, made with biotin, is added into the brush and seeps down the brush’s teeth to infuse your hair along with the red light during treatment. The pairing of light therapy and serum makes for even more efficient results. Best of all, you can even add minoxidil to really maximize the effects!
Experiments run using this brush + serum pairing led to 39% improvement in hair growth in just 20 weeks. All you need to do is apply it up to five minutes per day, every day, and you can benefit from the increased nutrition and follicle stimulation.
The laser hair growth brush comes with a USB charging cable to keep the built-in battery fully topped up, as well as an instructions manual that details the step-by-step process for safe, effective use (and cleaning when necessary). However, some users have complained that the manual isn’t very easy to understand or clear on the directions.
While some people have reported that this laser hair growth device feels comfortable and soothing, others with very fine hair have reported pain and discomfort when using this brush.
Pros
It can be used in conjunction with a serum
Encourages a 39-percent growth of hair over 20 weeks
Serum contains biotin that helps to make your roots stronger
Use it for three to five minutes every day
Cons
Instruction manual isn’t very clear
Users reported pain and discomfort when using brush
One of the exciting features that sets this BIOEQUA hair growth device apart from the rest on the market is that you can use it for facial hair as well as the hair on your head. It can help to thicken your beard, moustache, eyebrows, or sideburns—great for guys who want richer, fuller facial hair.
The device uses pulsed cold ions to increase nutrient and oxygen exchange with your hair follicles, improving blood flow as well. The pulse electrical fields also stimulate the hair follicles themselves, shifting them from “resting” into “growth” phase.
With just three minutes of use per day, you can see results in as little as four weeks. Best results will set in around 3-6 months, however (pretty standard for all the hair growth devices on our list). In addition to the device (and accompanying charger), the package also includes an “Energizing Scalp Spray” to improve scalp health and increase the effectiveness of the light therapy device.
There have been some complaints about the company itself and less-than-ideal customer service. It also doesn’t include a money-back guarantee.
While it does work, some complaints state that it works slowly than advertised, giving only minimal results in the 6-month use period. However, this may be the result of people using it incorrectly or not doing the treatments daily as recommended.
People have reported issues with the company, stating that there’s no money-back guarantee on this product. This is something to bear in mind before purchasing it. Others have said that while the device works for them, it does so at a slow rate. You must be committed to using this regularly to see results.
Pros
Pulsed electrical fields to improve the quality of hair
Only have to use for three minutes every day
Stimulate hair growth on other areas
You can get results within four weeks of use
Cons
User reviews reports doubtful results in hair growth
Laser hair growth devices make some pretty big promises—visible hair re-growth in just 3-6 months!—but how well do they actually deliver? And do they all provide the same results, or do only some work?
Before you buy any of the products above, let’s take a deep dive into everything you need to know about laser hair growth devices—starting with the most important question:
How Do Laser Hair Growth Devices Work?
Laser hair growth devices use something called “low-level laser therapy” (LLLT). Simply put, they beam low-level laser lights (emitted from LED diodes or lasers) into your scalp, stimulating both the scalp itself and the myriad follicles that grow your hair.
The photons emitted by the laser lights penetrate your scalp and are absorbed by your hair follicles. The light actually shifts the follicles from the “resting” phase to the active “growth” phase.
Remember, hair grows in three stages:
Anagen, or growth phase
Catagen, or transition phase
Telogen, or resting phase
Typically, 90-95% of your hair is in the anagen phase. However, baldness is the result of the hair being “stuck” in the telogen phase for too long. Over time, the hairs weaken and the follicles become less effective at growing healthy, strong hair. Eventually, it thins and falls out—what you see as “baldness”.
Laser hair growth devices work by:
Extending the anagen (growth) phase of healthy hairs
Shifting the hairs in telogen phase into active growth phase
The light also encourages the body to increase the production of ATP, which releases nitric oxide, stimulates metabolic processes, and increases oxygen and nutrient delivery to the scalp and hair follicles. All of this helps to increase the health of your hair follicles and scalp, encouraging healthier, stronger hair.
Do Laser Hair Growth Devices Actually Work?
There isn’t actually a lot of concrete evidence to prove that these laser hair growth devices work as they claim to. Some studies have been done confirming the effectiveness of LLLT (as you’ll see below), but experts agree that the “results of laser therapy are inconsistent” and the “conclusion of the medical community seems to be that it appears to work for some people, but not for others” [1].
The U.S. National Library of Medicine [2] has a list of 15 clinical trials conducted into the effects of LLLT for hair regrowth, and the preliminary results are promising:
One 2014 study [3] found that LLLT for the scalp “significantly improved hair counts in women with androgenetic alopecia”, adding onto a 2013 study [4] that proved that LLLT “significantly improved hair counts in males with androgenetic alopecia”.
A 2009 study [5] into the HairMax comb (listed above) concluded, “results of this study suggest that the HairMax LaserComb is an effective, well tolerated and safe laser phototherapy device for the treatment of androgenetic alopecia in males”.
Another 2014 [6] study reinforced the data above, stating, “LLLT for hair growth in both men and women appears to be both safe and effective. The optimum wavelength, coherence and dosimetric parameters remain to be determined.”
Even more “official” sites like WebMD have mostly positive things to say about laser hair regrowth devices, citing studies that provided encouraging preliminary results into these methods’ effectiveness for treating baldness.
However, they do highlight one important fact [7]: “For patients experiencing the earlier stages of hair thinning and loss, laser caps can be effective in treating and slowing this loss. No treatment can completely stop hair loss, especially when due to genetics. However, laser caps and other non-surgical hair restoration methods can slow the progression of hair loss when used consistently.”
Well, that’s definitely encouraging! Laser hair growth devices may not be able to fully stop or reverse hair loss (like they claim), but they can at least slow it down. You may get a few more years of healthy, thick hair thanks to the devices on our list above.
Lasers vs. LED Light Hair Growth Treatments:
With Low Level Laser Therapy devices like those on our list, there are one of two treatments used: lasers or LED lights.
On the surface, they’re both pretty similar. They both emit light within a certain wavelength (typically on the infrared spectrum) with the intention of stimulating hair growth, increasing follicle activity, and improving blood flow to the scalp.
However, there are some differences between the two that you need to know before you choose which laser hair growth device you buy:
Light Coherence – Lasers emit “monochromatic” light on a single wavelength, while LEDs emit multi-colored light in a broader range of wavelengths. What does this mean?
Laser lights are more focused (coherent) with a narrow beam that is more easily targeted for precision, which is why it’s used in so many medical treatments. The specific wavelengths of laser light will penetrate deeply into your scalp and activate the hair follicles.
LED lights, on the other hand, won’t penetrate as far into your scalp. The effects will be mostly on the surface.
Wavelength – The “ideal” wavelength for stimulating hair follicle function is 680 nm. Lasers can be specifically modulated to emit light of this wavelength, but LED lights are far less specific and thus less effective at stimulating hair growth.
Power – Lasers are, as you probably guessed, a great deal stronger than LEDs. They generate a great deal more power, which means the light is more likely to remain coherent and retain its energy as it penetrates through the scalp to reach the hair follicles.
These three differences are actually incredibly important! Just reading over them, you can instantly see that LED devices have far less potential effectiveness than devices that use lasers. Make sure that you only buy products that use lasers if you want the best possible results.
Other Possible Hair Growth Treatments:
The FDA has approved two drugs for treating pattern baldness [8]:
Finasteride – Finasteride (sold under the name Propecia) prevents the production of DHT, the hormone that is largely responsible for male pattern baldness. It’s said to be about 90% effective at slowing hair loss in men, and may even lead to some hair regrowth. The effects will only last as long as you’re taking the pill (once a day).
Minoxidil – Minoxidil (sold under the name Rogaine), stimulates hair growth, though the precise mechanics of how it works aren’t fully understood even after years of use. It won’t, however, stop your hairline from receding because it doesn’t block the DHT that is causing the hair loss. It’s said to work in around 66% of the population, most effective for men under 40 who have just begun losing hair. It’s a topical application you apply directly to your scalp. Results may take up to 4 months to present, but like finasteride, it will stop being effective as soon as you stop applying it.
Experts also recommend biotin for treating hair loss. Biotin, or Vitamin B7, increases follicle growth by helping your body to produce more keratin, the protein used to form new hair cells. Consuming a lot of biotin-rich foods—such as eggs, meat, vegetables, nuts, and seeds—can provide the body with more Vitamin B7, strengthening and protecting the hair.
Pros and Cons of Laser Hair Growth Devices for Hair Loss
Pros:
Easy to use at home. Simply slip on that hat, band, or helmet, and let the laser light therapy does it work!
Non-invasive. No surgical procedures are necessary, and there’s no need to visit a hospital or clinic.
Painless. You may feel a bit of heat on your scalp while the device is active, but the light won’t typically cause discomfort and certainly not pain.
No side effects. Minoxidil and finasteride (the two FDA-approved hair loss medications) both include a number of side effects—including acne, skin rash, inflammation, decreased sex drive, and erection and ejaculation difficulties—that may stop you from taking them. Hair growth devices, on the other hand, are perfectly safe and side effect-free.
Cons:
Potentially ineffective. Remember that these devices are not true medical therapies (in a clinic using proper equipment). As mentioned above, there is a very real possibility that they will have no effect in slowing or reversing your hair loss because LLLT just doesn’t work for some people or some forms of baldness.
Lack of conclusive evidence. Research has just begun to scratch the surface on concrete scientific proof that LLLT works as a treatment for baldness. Most of the devices sold today are manufactured using incomplete data and aren’t backed up by thorough testing.
Quality may vary. Some less-than-ethical manufacturers have rushed to put out “popular” products without doing proper research, testing, and analysis of what they’re putting out. Quality control is a very real problem with many of the devices available online, a large percentage of which are manufactured in China.
What to Consider Before Buying Laser Hair Growth Devices
If you’ve gotten this far and still want to give laser hair growth devices a try, good for you! It’s at least worth trying to stop hair loss in its tracks before it turns into full-on baldness. You might not be ready for surgery or medications quite yet, but you’re taking steps to combat hair loss before it gets too bad.
Here are the important factors to consider when shopping for laser hair growth devices:
Type – There are four different types of laser hair growth devices available to you:
Caps – These are the most discreet of the laser hair growth devices. They look just like a regular baseball cap, and you can wear them anywhere without drawing attention to what you’re doing. They typically are worn for sessions ranging between 6 and 30 minutes, used either daily or 2-3 times per week. However, for those with a large amount of hair and only small patches of thinning, they might not be maximally effective because the existing healthy hair may prevent the laser light from reaching the scalp.
Helmets – Helmets are a bit bulkier and more noticeable than caps, but they tend to have more power and are often better-designed. They share the same downside as caps—thick hair may interfere with the emitted light—but typically last longer and are less prone to malfunctions.
Combs – Laser hair growth combs are handheld devices that allow you to directly stimulate the parts of your scalp where your hair is thinning. Their bristles can massage your skin to increase circulation, and you can use the comb to brush thick, healthy hair out of the way for direct and effective treatment of bald or thinning spots. However, you have to operate them by hand, and it can grow quite tiresome to brush your hair for the full duration of the therapy session (ranging from 3 to 15 minutes).
Headbands – Headbands can cover more scalp area than combs, but will be more versatile and discreet than helmets. Typically, they come with fewer laser diodes than helmets, but more than combs. You can treat only the problem areas where your hair is thinning, or you can use it to stimulate growth across your entire head—all you have to do is place it correctly and let the light do its work!
Size – If you’re choosing a helmet or cap-style device, you need to take into account the size (circumference and shape) of your head. You might not be able to fit the “standard” cap size (your head is too large or too small). Many of the negative user reviews about the cap and helmet-style devices complain about the devices being painfully tight or uncomfortable because they cannot be adjusted to accommodate unusual head sizes or shapes.
Extent of Hair Loss – How widespread is the hair loss? Are you dealing with small patches in specific locations (receding hairline, bald patch on the top of your head, etc.) or with full-head thinning or balding?
For “spot treatments” in specific locations, you might be better off with a band or comb that allows you to target precise patches. For more widespread hair loss, you might want to choose the cap or helmet-style device that can treat your whole head at once.
Cycle Time – This is also known as “session time”, or how long each cycle/session of treatment lasts. As you saw from the list above, some devices opt for 20-30 minute sessions 2-3 times a week, while others prefer 3-10 minute sessions daily.
The effectiveness won’t usually change based on the session time—by the end of the week, you’ll have accumulated roughly the same amount of treatment minutes. But what will change is the convenience level. If you find it hard to slot in 20-30 minutes for treatment every day because of your busy schedule, you may want to opt for a device that utilizes a much shorter daily cycle.
FDA Clearance – This is an absolute must! FDA-approved devices have been rigorously tested for safety (if not effectiveness), meaning they meet certain quality control and operational standards. Devices that aren’t FDA-cleared/FDA-approved are usually manufactured overseas with far less quality control or oversight. They are the devices most likely to malfunction or overheat.
Laser Count – There is no “standard” laser count, but it’s safe to say that more is typically better. The more lasers there are in the device, the wider surface area it can treat and the more likely it is that the light will penetrate through healthy hair and your scalp to actually reach the follicles.
Laser Wavelength – As mentioned above, the ideal laser wavelength for stimulating your hair follicles is 670 nm. However, laser hair growth devices will typically use lasers in a wavelength range of 630 to 680 nm. The closer to 670 nm, the more effectively the light will work!
Portability – You may not want to stop your LLLT sessions just because you’re traveling for work or holiday. If you anticipate the possibility that you’ll travel, consider buying a laser hair growth device that you can pack and take with you. The headband and comb-style devices are far more compact, but a cap-style device may be a good option. Helmet-style devices are best for at-home use but are far too bulky to bring in your luggage.
Price – Price certainly isn’t the most important factor—after all, quality is what matters most—but it’s something to take into account. The top-priced options aren’t necessarily the best, and you can find cheaper models that deliver results on par with the premium picks. That’s why it’s so important to do your due diligence and thoroughly research the pros, cons, and specs so you can find the device that will deliver maximum bang for your buck!
FAQs:
Do more lasers grow hair faster?
More lasers won’t stimulate faster hair growth. They simply provide wider coverage, meaning they can treat larger areas at once.
Can laser helmets be used with other hair loss products?
Most LLLT devices are actually recommended to be used in conjunction with other remedies and treatments. For example, the Glemme comb has an aperture into which you can pour biotin serum, which you can comb into your hair to maximize the effectiveness of the treatment.
LLLT can even be used alongside finasteride or minoxidil. One study [9] found that LLLT had no adverse effects when combined with these FDA-approved medications, but represented “a potentially effective treatment for both male and female androgenetic alopecia”.
However, be warned: if you apply the minoxidil to your hair before using LLLT, the light may actually burn or irritate your scalp. Better to use the laser hair growth device first, then apply the topical treatment afterward.
Does Low-Level Light Therapy (LLLT) hurt?
Not at all! In fact, you won’t even feel warmth because the low-level lasers used by hair growth devices are considered “cold lasers” because they don’t generate heat. There is no vibration, itching, or prickling sensation, either. It’s an entirely painless and discomfort-free form of treatment.
What are the possible side effects of using laser hair growth caps?
The most common side effects include: dryness, itching, flaking, redness, or scalp irritation. This has nothing to do with the lasers, but more to do with the cap itself. Wearing a cap for prolonged periods of time can put pressure on the scalp, pull on your hair, and increase the presence of scalp bacteria (which contribute to itching and irritation).
Do I need a prescription to use a laser hair growth cap?
No prescription is needed! Only finasteride will require a prescription; minoxidil is an over-the-counter treatment and biotin can be found in virtually every supermarket and pharmacy. Laser hair growth devices like those on our list are also considered OTC treatments and thus do not require a prescription to purchase or use.
