The illumiFlow hair growth cap promises to “regrow your confidence – or your money back”, offering 6 months money-back guarantee and a 5-year warranty on both laser caps – one with 148 lasers, and the other with 272 medical lasers.

Results are expected within 4-6 months of treatment, and the first result to expect is a reduction in hair loss, followed by new, thickened hair growth.

The 272-laser model costs less than half of the HairMax PowerFlex but offers no choice between pulsing/constant light, and the total output is not mentioned in its specs.

4. iRestore Helmet for Hair Regrowth 

laser cap for hair growth irestore
iRestore hair growth helmet – best price on Walmart!

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 just 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 43% increase in hair count, after using the iRestore for 30 minutes every other day.

irestore before and after
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.

The best part?

You can expect results in 3-6 months, and if you don’t see any visible improvement in your hair growth – you can send it back for a full refund.

  • iRestore specs: 21 medical-grade lasers (power: <5mW – Low-Level Laer) & 30 LEDs (650 nm – proven optimal wavelength for hair growth).

(LEDs blink for more stimulation while lasers stay constant)

  • Size: 10.7 x 9.2 x 6.1 inches
  • Weight: 1.7 pounds
  • Power: 110-220V (comes with AC adapter)

iRestore Laser Hair Helmet Pros:

  1. Excellent coverage – the lasers diodes and LEDs are speckled all over the interior of the helmet.
  2. 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.
  3. 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.
  4. One year warranty and 6 months full 6-months money-back guarantee
  5. Excellent customer service
  6. Long shelf life – the iRestore was tested in a world-renowned lab to last at least 5 years.
  7. 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.
  8. Can be used along with any other hair loss treatments (we recommend trying Jamaican Castor oil).
  9. It is very comfortable to use – it has small cushions all around it so it’s completely painless to use it.

Cons

  1. 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.
  2. Needs to stay plugged in during treatment. However, you can go completely mobile if you buy the rechargeable battery pack (very much worth the spend!)

✅ iRestore Best Price – When we check this page on Walmart, we often find the iRestore on a sale price. If you find it for less than $500- it’s a good deal.

Here’s something interesting:

The FDA approved 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.

Conclusion

Through our research, we have concluded that the best laser cap in the market now is the HairMax PowerFlex Laser Cap.

It is the most powerful laser hair growth caps, but it’s the most expensive one as well. Our runner up would be the illumiFlow laser cap or the Kiierr Laser cap.

Bosley (Capillus) Laser Cap Review: Does it Work? 

Capillus laser cap review
The Capillus82 laser cap – not our first choice

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 $900 for the 82-laser one, and almost $2000 for the 282-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.

👉 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.

But:

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.

Are Laser Hats/Helmets PROVEN to Regrow Hair?

Can you imagine it?

No more inconvenient and expensive visits to laser hair clinics, costly prescription drugs, messy topical creams (though you can keep using them along with your laser helmets), and no hair transplants.

(And…you’ll be saving between $3,500 and $5,000 for laser clinics per year!)

The laser caps you’ve found here have been clinically shown to:

1. Grow new hair.

2. Double the follicle diameter of existing hair (reverses miniaturization).

3. Slow (and even stop) hair loss.

how laser regrows hair

(See EXACTLY how red light therapy for hair loss works!

But:

If you truly want it to work (and I know you do) – you’ll have to be consistent with your home treatments.

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

Of course you can.

How to use a Hair Growth Helmet 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 which 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.

Red light therapy will not heat your scalp, but tingling sensation after use is normal (it happens because it increases blood flow in your scalp – which is good.)

Laser Caps FAQ

There are literally dozens of frequently asked questions about LLLT for hair loss home treatments, here are the answers to most of them:

What is a laser cap?
A laser cap (hair growth helmet) uses safe, low-level lasers/LEDs to energize hair follicles and spur new, natural hair growth, by boosting blood circulation to the hair follicles.
How long should you use a hair growth helmet?
Laser helmets treatment time varies greatly, depending on the number of LEDs/lasers. Treatment time ranges from 5-20 minutes per session, 2-3 times a week.
Can laser helmets be used with other hair loss products?
Yes. It can be safely used with other products such as Rogaine and Minoxidil, and in fact, laser therapy can help make these other treatments more effective.
Are laser caps safe?
Generally, laser hair treatment uses low-energy nonionizing safe radiation. Pregnant women should not use them before consulting with their doctor. If you are taking 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?
The science-based answer is NO. Laser 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 totally different wavelength from red light therapy.

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

Do you have to cut your hair to get the laser to work?
Your hairstyle and length will not interfere with your LLLT home treatment because it has a cascading effect and a systemic effect, which will result in improvement outside the covered treatment area. Some people say that laser combs can reach the scalp better than helmets – because the comb design makes you part your hair and allow the light energy to reach your scalp better.

👉Check out my post about the laser comb.

Do you have to keep using the laser cap to keep the results?
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 does 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.

Basically, because the follicles have “weakened,” they need constant revitalizing from the lasers (or whatever other treatment you are using).

However:

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

Do laser caps work for dark hair?
Yes, they 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.
Can laser caps be used after hair transplants?
Yes, however, it’s advised to wait at least 30 days before you start using it, and consult with your surgeon to be on the safe side.

I truly hope you’ve found my research and tips useful.

    • 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.

  1. 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.

  2. 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.

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

    Reply
    • 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.

  4. 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.

  5. 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.

  6. 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?

    • 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.

    • 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

  9. 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.
