Can a funny looking helmet with a bunch of tiny light bulbs in it stop your hair loss and even regrow thicker, fuller hair?
Do laser caps (hair growth helmets) work?
The answer, according to science, is a definite YES.
And the best part?
LLLT is a non-invasive, painless and completely safe way to stimulate hair follicles to grow thicker, fuller and even more pigmented.
(I’ll point you to many of the studies – all of them listed at the end of the post).
In this post you’ll find the 3 best FDA cleared laser caps for hair regrowth, their pros and cons, and a full comparison between them – to help you make the best choice for your needs.
The 3 Best Laser Caps for Hair Growth
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’ll find below 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 this post to find out how exactly LLLT regrows hair)
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.
Ready? Here we go.
1. iRestore Laser Hair Treatment System
The FDA Cleared iRestore hair loss laser treatment helmet was designed for both men and women with receding hair line, balding and thinning hair – and is one if the highest rated laser hair helmets on Amazon.
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 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 medical grade 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 System 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 almost 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).
- The helmet does not cover the backside and the sided 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.
- Won’t work for people with no live follicles (completely bald)
☑️ iRestore Best Price
When we check this page on Amazon, we often find the iRestore on a sale price. If you find it for less than $600 – it’s a good deal.
2. 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 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.
The iGrow price is lower than the iResore.

☑️ iGrow Best Price
The iGrow sells for $549 on the official website. But on Amazon we often find it for much less. Check this page to see today’s price. If it’s less than $430 – grab it.
3. Theradome Hair Growth Helmet
The Theradome portable laser cap is the most expensive one on this list, but definitely the most powerful one in terms of technology.
It has more than twice laser diodes than the first two ones – 80 laser diodes (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.

☑️ The BEST Laser Hair Growth Cap WINNER
Through our research, we have concluded that the best laser cap in the market now is the iRestore.
It has high user reviews and success rate, it’s well made, easy and comfortable to use, and the price is average (for laser caps).
On the surface, the Theradome seems to be the most powerful laser hair treatment at home, but the price is so high that it would not be our first choice.
We would try the iRestore or the iGrow first, and if we discover laser hair therapy works for us – we would upgrade to the Theradome.
Laser Caps Safety & FAQ
There are literally dozens of frequently asked questions about this LLLT for hair loss home treatments, here are the answers to most of them:
1. How do laser hair helmets treat hair loss?
Laser therapy, when used properly, improve hair follicle function and reverse the effects of hereditary hair loss by helping the follicles to produce a thicker, longer, healthier and more pigmented hair.
See the full answer for how it works (without any side effects) and scientific proof in our post about red light therapy for hair loss.
2. Are laser caps safe? Who should not use them?
Generally, laser hair treatment uses low-energy non ionising 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.
3. Can Laser Caps cause cancer?
The science-bases 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.
4. 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 which tested the best way to use them to get 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.)
5. Can laser hair growth 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.
6. Do you have to cut your hair to get the laser to work?
Your hair style 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.
Got you curious? check out my post about laser combs HERE.
7. 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 what ever 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.
8. Do laser caps work for dark hair?
Yes, they can work for dark hair.
However, you should know that 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.
9. 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.
