4. iRestore Helmet for Hair Regrowth
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:
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.
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:
- Excellent coverage – the lasers 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.
- One year warranty and 6 months full 6-months money-back guarantee
- From what I found here, the company (Freedom Laser Therapy) offers excellent customer service
- Long shelf life – 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 – see why HERE).
- It is very comfortable to use – it has small cushions all around it so it’s completely painless to use it.
- 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. 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.
5 iGrow Laser Hair Growth Helmet
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.
You even get the same 6-month money-back guarantee if it doesn’t work for you.

6. Theradome Hair Growth Helmet
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.
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 recommended by hair rejuvenation experts such as Bosley and HairClub.

Through our research, we have concluded that the best laser cap in the market now is the HairMax PowerFlex Laser Cap.
Capillus Laser Cap Review: Does it Work?
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.
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.
(See EXACTLY how red light therapy for hair loss works!
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:
👉 Here’s a study proving red light therapy safe even when skin cancer is present.
👉Check out my post about the laser comb.
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).
Once you finish the suggested treatment period, you can cut down to “maintenance” treatments of once or twice per week.
I truly hope you’ve found my research and tips useful.
