Laser Hair Growth Caps & Helmets: 6 Brands You Can Trust [2024]

best laser caps and hair growth helmets

Can a helmet or a cap with a bunch of tiny light bulbs in it stop your hair loss and even regrow thicker, fuller hair?

Do laser hair growth caps and helmets work?

According to science (and thousands of testimonials), the answer is YES.

That’s why many doctors and hair restoration specialists prescribe a laser cap to their patients.

Low-level laser therapy has been clinically shown to effectively treat hair loss (androgenetic alopecia), prevent receding thinning hair, and regrow thicker, fuller hair – in 3-6 months.

And the best part?

A laser cap is a non-invasive, painless, and completely safe way to stimulate hair follicles to grow thicker, fuller, and even more pigmented.

(The many studies are listed at the end of the post).

How Do Laser Caps Help Regrow Hair?

To understand how infrared hair growth caps can regrow hair, you should know that hair growth is a natural process that occurs in cycles.

Each hair strand goes through a growth phase (anagen), a resting phase (telogen), and a shedding phase (catagen).

Hair loss or thinning can happen when this cycle is disrupted or when hair follicles become dormant.

Imagine your hair follicles as mini-gardens that need sunlight to thrive. In this analogy, laser caps act as the sun, providing a boost of energy to stimulate hair growth.

Just like plants need sunlight for photosynthesis, your hair follicles require light energy to produce and maintain healthy hair.

Laser caps provide this energy to the hair follicles and “wake them up”.

(Want to know more? See exactly how red light therapy for hair loss works)

What is the Best Wavelength for Hair Growth?

According to studies, the best wavelength for hair growth is between 630nm to 660nm.

Red light therapy with a wavelength of 650nm has been found to be the most effective and practical wavelength for stimulating hair growth, which is why most laser caps use this exact wavelength.

2. HairMax 272 PowerFlex Laser Cap Longest Trial

hairmax powerflex review

  • Treatment time – 7 minutes – 3 times a week
  • Lasers – 272, full coverage
  • Irradiance – 1360 mW’s
  • Trial time – 6 months

😍 Pros – Portable and convenient with a rechargeable battery pack, reputable brand, FDA-cleared, high-strength,

😣 Cons – Expensive, some complaints about battery life per charge

$1499 at Hairmax

The HairMax PowerFlex also has the same specs – 272 medical-grade lasers, full scalp coverage, and a total output of 1360 mW’s, but the price is much higher than the Kiierr laser cap. In fact, it’s double the price.


Because the Powerflex has a dual operating mode technology for a choice of constant or pulsing laser lightwave for 15-minute or 30-minute treatment time.

Also, the treatments are needed just 3 times weekly, and you get the longest free trial in the industry – one year.

The flexible design, which looks like a regular sports cap, is 100% portable and comes with a built-in rechargeable battery pack.

The silicone inserts (water-resistant for easy cleaning) conceal the 272 lasers and internal circuitry while protecting the diodes and keeping them clean.

Treatment time is 15-30 minutes – 3 times a week – and you can choose a constant or pulsating laser with the dual operating mode.

The HairMax laser cap helps restore your hair’s natural growth cycle by promoting blood circulation and oxygen while boosting DHT elimination (high levels of DHT can cause hair loss) – resulting in increased density, fullness, and growth.

HairMax PowerFlex Pros

  1. Discrete hair treatment – flexible sports cap design
  2. 100% portable
  3. A Comfortable laser cap
  4. Powerful – 1360 mW’s output
  5. An easy-to-use controller with an illuminated timer and battery level indicator

  • Trial time – 6 months, 5-year warranty

😍 Pros – flexible and comfortable, long warranty, up to 20,000 treatments, high strength, FDA-cleared, reasonable price

Available at Illumiflow ($845 with code NEW140 ), and on Amazon ($625)

4. iRestore Laser Helmet for Hair Regrowth 

irestore laser helmet for hair growth review

  • Treatment time – 30 minutes – 3-4 times a week
  • Lasers – 21 + 30 LEDs (650 nm), full coverage
  • Trial time – 30 days (Amazon standard)

$599 on Amazon

I’m not a fan of the helmet. It’s made of rigid plastic and you can’t wear it while you are out and about.

It also doesn’t mold to the shape of your head.

However, I had to add it to the list because the price is lower for these types of laser hair growth devices.

The FDA Cleared iRestore hair loss laser treatment helmet was designed for both men and women with a receding hairline, balding and thinning hair.

And that’s not all:

iRestore was proven to promote significant hair growth in a 2017 clinical study.

When this 16-week study ended, 100% of men and women saw a visible improvement in hair growth, with more than a 43% increase in hair count, after using the iRestore for 30 minutes every other day.

iRestore before and after

The 51 medical-grade lasers and LEDs inside the helmet radiate light energy that is absorbed by the hair follicles to enhance cell metabolism rate and reactivate follicles to stimulate hair growth.

Dermatologist Dr. Andrea Suarez has had wonderful results with the iRestore helmet, and during her 18-month journey with the iGrow has noticed an increase in hair strength, reduced hair breakage, and an increase in hair thickness, particularly in her ponytail.

irestore hair growth helmet review

iRestore Laser Hair Helmet Pros:

  • Good coverage – the laser diodes and LEDs are speckled all over the interior of the helmet.
  • No over-use risk – built-in automatic shut off after 25 minutes. You can also shut off the unit at any point during hair treatment.
  • Eye damage prevention – The iRestore Laser Hair Growth helmet has two sensors placed inside the cap, to prevent the cap from emitting laser unless it is fitted on your head.
  • Long life span – the iRestore was tested in a world-renowned lab to last at least 5 years.
  • Fits most head sizes comfortably – the system will generally fit a head circumference range of 21 to 24 inches. There’s an adjustable component inside that allows for proper fit.
  • Can be used along with any other hair loss treatments (we recommend trying Jamaican Castor oil).
  • Comfortable to use – it has small cushions all around it


  • Low power compared to the top competitors
  • The helmet does not cover the backside and the side of the head directly above the ears. However, (Low-Level Light Therapy) has a cascading effect that, if given the time, will result in improvement outside the immediate treatment area to benefit the entire scalp.
  • Needs to stay plugged in during treatment, and you can’t go out and about with it.
  • Doesn’t mold to the shape of the head

✅ Available on Amazon ($599)

5. iGrow Laser Hair Growth Helmet

igrow laser helmet review

  • Treatment time – 30 minutes – 3-4 times a week
  • Lasers – 21 + 30 LEDs (650-670 nm), partial coverage
  • Trial time – 30 days Amazon standard

Here’s something interesting:

The FDA-cleared iGrow is an almost identical device to the iRestore laser helmet in terms of optical and electronic function (21 laser diodes, 30 LEDs – 650-670 nm, delivered at 3-4 joules per cm2).

Actually, All the technology is the same except for the design and the audio earphones you can see in the image.

You even get the same 6-month money-back guarantee if it doesn’t work for you.


It’s also been proven to increase hair count (by 36%) in 16 weeks – in two published clinical studies.

Equipped with headphones and an iPod/MP3 interface


The iGrow price is lower than the iRestore.

iGrow pros

  • Lower price than all laser caps We’ve found
  • Comfortable and easy to use
  • Good for travel – very easy to take through airports and use while away from home
  • The headphones are of high quality and the sound is excellent
  • Automatic shut off after 25 minutes
  • Excellent customer service, available at all times
  • From what I found here, many users insist that it works if you are consistent. You can see their before and after pictures too.


  • Low power compared to the top competitors
  • Amazon users rate this one lower than the iRestore.

✅ Available on Amazon ($449)

6. Theradome Hair Growth Helmet

theradome laser helmet for hair loss

  • Treatment time – 30 minutes – 3-4 times a week
  • Lasers – 80 (670 nm), partial coverage
  • Trial time – 30 days

The Theradome has 80 medical-grade lasers (678 nm low-level laser) to be exact – and no LEDs.

This means that potentially, you will get quicker and better results than the iGrow and the iRestore.

If used as directed, Theradome claims to stop hair loss within 18-26 weeks, regrow hair within 28-52 weeks, and provide fuller, thicker hair after 100 weeks.

Also, the Theradome is cordless (comes with rechargeable batteries), meaning you are free to walk around with it.

Theradome is manufactured in the USA and is recommended by hair rejuvenation experts such as Bosley and HairClub.

  • 80 laser diodes and full coverage (you can get the 40 LEDs model – the Theradome Evo laser hair growth device – for about half the price on Amazon)
  • Portable hair growth device
  • Counts your treatments – an automated treatment counting system keeps track of the total number of treatments you’ve undergone.

  • Much more expensive than the last two

 Capillus Laser Cap Review – Why Pay More?

Capillus bosley laser cap review

The Capillus company, which sells 3 low-level laser hats/caps, claims that you’ll regrow your hair – in only 6 minutes a day.

And the price matches the claim – almost $450 for the 82-laser one, and almost $1200 for the 202-laser cap.

(Forget about the pro model – with 272 lasers – which costs about $3000. 🙄)

Through our research, we’ve found that there is very little evidence to support the efficacy of the Capillus caps (they’ve conducted no clinical trials), and buyer reviews are less than stellar.

capillus laser ca<span data-mce-type=[p review” width=”200″ height=”322″ />

👉 You can see all the Amazon buyer reviews HERE.

Yes, it’s completely mobile, and you can use it outdoors with no one knowing your little secret.


We conclude that if you’ve never tried laser hair growth treatments and proved that this home technology works for you, the huge investment may not be worth it.

Will a Laser Hair Growth Cap Work for You? 

Laser caps utilize Low-Level Laser Therapy (LLLT) as a scientific principle.

It involves using safe, low-intensity lasers to deliver light energy to the scalp, stimulating cellular activity within the hair follicles.

This stimulation helps to promote hair regrowth and improve the overall condition of the scalp.

A 2019 study published in Lasers in Medical Science found that a laser therapy helmet increased hair thickness and covered bald patches in men and women with androgenetic alopecia.

Similarly, a 2018 study in the Indian Journal of Dermatology, Venerology and Leprology linked low-level laser therapy to improved outcomes and image satisfaction in androgenetic alopecia patients.

how laser regrows hair


If you truly want it to work (and I know you do) – you’ll have to be consistent with your home treatments. According to dermatologist Dr. Anna Chacon, it is ideal to repeat the treatment routinely for the best results.

Can you do that if the result is new, shining baby hair?

Of course you can.

Are There Any Side Effects From Using Laser Caps?

Laser caps are generally considered safe and have minimal side effects. However, there are potential side effects that should be taken into consideration:

1. Scalp irritation – some people may experience scalp irritation or itching after using a laser cap (this means that blood is flowing into the area – which is good). If you feel your scalp is very irritated, adjust the intensity of the laser (if possible) or reduce the treatment frequency.

2. Redness and swelling – in some cases, laser cap therapy can cause temporary redness and swelling on the scalp. This is usually mild and resolves on its own within a few hours.

3. Hair shedding – laser cap therapy can cause temporary hair shedding in some people. I was alarmed by this and stopped using my laser cap, which was a mistake.

I later found out that this shedding is a natural part of the hair growth cycle and is typically followed by new hair growth.

If you take medications that affect skin sensitivity to light, consult with your doctor before use. Do not use LLLT if you have skin cancer on your scalp.

Can Laser Caps Cause Cancer?

According to research, laser cap treatments for hair loss do not cause cancer.

More than 2000 clinical studies were conducted on the use of LLLT and all of them have found no DNA mutational effects resulting from treatment.

The short UV waves (280 – 400 nm) are the type of waves that have been linked to skin cancer, and they are at a different wavelength from red light therapy.

👉 Here’s a study proving red light therapy is safe even when skin cancer is present.

How to use a Laser Cap Safely

First, always follow the instructions.

Do not be tempted to use the device more than directed – it won’t work better or faster if you do, and the instructions are based on clinical studies that tested the best way to use them to get the best results.

Second, do not stare directly at the laser lights – they are very bright. If you are worried, use goggles.

Do You Have to Keep Using the Laser Cap Forever?

Yes, you do have to keep using the laser cap to keep the optimal results of hair growth.

However, with time you can reduce the frequency of usage to once a week. As with any other hair loss treatment (other than hair transplant) – the answer is yes.

In fact, through my research, I’ve found that a few users who thought that the treatment did not work for them discovered that their hair started falling out when they stopped using it and realized that their helmet actually stopped their hair loss.

Because the follicles have “weakened,” they need constant revitalizing from the lasers (or whatever other treatment you use).


Once you finish the suggested treatment period, you can cut down to “maintenance” treatments once or twice a month.

Do Laser Caps Work for Dark Hair?

Yes, laser caps can work for dark hair. However, you should know that the FDA has not cleared these devices for dark skin.

Refer to the Norwood-Hamilton Scale (approved: Class Ila to V) / Ludwig-Savin Scale (approved: Class I to II) and Fitzpatrick Skin Type Scale (approved: Type I to IV) for compatibility.

28 thoughts on “Laser Hair Growth Caps & Helmets: 6 Brands You Can Trust [2024]”

  1. I had Capillus until it broke. Now, I have Kiierr 272, & it is amazing. I will still buy the broken battery for Capillus since it was super expensive (& use them both). iRestore is garbage. The Theradome doesn’t even cover your head. The Illinistore thing looks great, but think of longevity. Nothing that twists & turns lasts. For example, with Capillus, I would wrap up the wire each time after use, which caused the battery to now work. It’s $800. So, I now have two caps. I did massive research & as of 2021, Kiierr 272 is the best product with the best results out there. Try it for 6 months. If you do not like it, return it. I doubt you will. Again, iRestore is garbage. You may want to be cheap about hair. If you do, you get crap results. I’ll say I once had that massive thing that floated on top of your head. It was the only one when it first came out, & it worked well, had good coverage, & it never broke. I traded it in for the Capillus. The battery breaking is so my fault. I should have never wrapped it around the battery (the cord) after each use. After a while, the cord seemed to break inside. I’ll get a new one so I have two amazing caps. Stay away from the cheap ones or the expensive ones which do not even cover your whole head. My advice, & I take anti-androgens, vitamins for hair, special shampoos, etc. I have a full head of hair, & I worked hard for it. Many would think I’m crazy. I don’t even use ROGAINE. Who would want to use that crap all day when its ingredient called Minoxidil is a pill. So I take the pill. Yes, it grows hair all over, but a small price to pay for lovely hair lol.

  2. It seems to me based on reading theres some biased on this article against theradome. It is not more expensive than the others and none are meant to relive dead follicules.

    As a consumer and reading every single vendor I find these companies arefocused on throwing each other under the buse. Kierrr apparently stoled immuniflows idea, irestore makes false claims of leds, revian offers the same and it’s over priced. Theradome has no user reviews but the ones they choose people to see. I can go on. The market is so deceptive one can only hope you chose the best. Nonetheless trust as a factor is merely surviving because of hair loss.

  3. I am very interested in trying a Laser hair growth device.
    I am a female and want to use it to boost my hair growth, as I feel my hair is just not growing (and has not been for years). *

    I am wondering, however, do the helmets actually give full coverage? Seems that side of the head and the lower back of the head are not covered by the helmets.
    I have, therefore, considered the combs/brushes – but are they really as effective as the helmets?

    I hope it is possible to get your advice.

    Kind regards,

    • Hi Solly, since the lasers boost blood circulation in and around their location to a certain radius, the entire scalp gets the benefits of it. Brushes are less powerful and require a lot of work – combing the hair slowly – and could take more than 10-15 minutes of “work”. Most people can not keep this routine consistently and thus reduce their chance of seeing results. I hope this helps :)

    • Laser and LED (light-emitting diode) both deliver a certain wavelength that is optimal for hair growth. They differ in speed, transmitting Distance, and cost. The Lasers are more powerful and operate at faster speeds than LEDs, and they can also transmit light farther with fewer errors.

  4. I put toppik hair fibers in my hair everyday. I want to use one of this helmets but I am curious if having fibers in my hair during treatments would “block” the lasers or make them less impactful because there is something in my hair and on my scalp. Or are the lasers powerful enough to just blast through any small amount of blockage to my scalp or hair follicles?

    The simple solution would be to just completely wash them out before I do a treatment, but as I said I put them in everyday and if I am doing treatments at different times, or need to run out after it would be annoying and more costly to reapply the fibers.

  5. It does help. Thank you. One last question please; I have very, very, very thinning hair at my forehead and sides of my head by my ears. Which would you recommend for me, the “I Restore Professional” (which Amazon does not have yet) with 82 lasers or the “Theradome Pro Lit 80” with 80 lazers. Thank you so much for your time and advice.

  6. I am wondering about the Hair Max. It has 246 lasers. Does that make it better than the Theradome?

    • It’s not better, it’s different. The HairMax is a light brush, which means you have to manually comb your hair slowly with it. The Theradome is a helmet, which you place on your head and is hands-free. The red light therapy brushes are better for people with thick hair which may prevent the light from reaching the scalp. The brush allows for the light to get closer to the hair follicles. So, this really depends on the type of your hair. I hope this helps.

  7. None of these companies addresses hat size.

    My hat size is 7-7/8, which is a circumference of 24-5/8″.

    I would be very disappointed and inconvenienced if I purchased a laser cap, it didn’t fit my head and I would have to send it back to the company for a full refund.


  8. There is no such thing as medical grade LED’s. LED’s have no clinical benefit at all and are used as on off switches in Chinese made electronics. With 21 lasers, irestore and igrow are the same, Theradome has almost 4 x the lasers. I’ve had mine for 2 years and I’ve seen constant growth.

  9. I am losing my hair in my temples, and its see through like a cheap wig across my front hair line. I am a 59 year old woman who used to have great hair. My hair line is mimicking male pattern baldness, with it recessing on either side of the center of my frontal hair line. While my temples are thinning out so badly and progressing towards the sides of my hair. My top hair hides it for now. The back of my head is doing great so far. Which device will help the front hair line, front and sides of my head and temple area best?

  10. It seems o.k to me, however I don’t know much about it and haven’t found user reviews anywhere. May be a new product. Also I don’t see any info about money back guarantee or warranty. I recommend shooting them an email and asking about it.

  11. I have the RedRestore Growth Cap with 148 lasers. It has only medical grade lasers and zero LEDS. I have seen significant hair growth with the system. The price is incredible for the laser power it offers.

  12. I have a NEW Theradome. It would turn on / charge for six treatments. Bought a new barrery. Turned on / charged for six more treatments.
    Theradome would not warranty the helmet or battery.
    Have no idea if it would help grow hair because it won’t recharge.


    • John,

      If you bought the Theradome from the official website or the authorized store on Amazon – you have a 1-year warranty against defects in materials and workmanship. Did you buy it from the official seller?

    • You say as a con of the theradome: “does not that advanced hair loss (dead follicles)” . No laser treats this. I’m confused why this would be a con of the theradome specifically

  13. As a comment on iRestore, the Black Friday/Cyber Monday price is $495. And they may have sales periodically throughout the year. That said, those suffering from hair loss probably shouldn’t wait for months to delay the purchase of a potentially helpful device… particularly with the money-back guarantee on the table.
