3 Best Red Light Therapy Hair Growth Devices That Do Work [2022]

How to stop hair loss and restore hair growth? Red light therapy can help with this. Learn about clinical trials, the best devices, and see the "before" and "after" — all in one article.

Many people start to panic and take immediate measures to preserve their hair when they see a dozen loose coats on the comb after the subsequent combing. Some take vitamins for hair loss without control, while others try to wash and comb their hair less often so as not to see any hair fall. However, hair must fall out and it is perfectly normal. A healthy person has a normal hair loss rate of 50 to 100 hairs per day. Hair grows cyclically, and new hair grows out of the bulb to replace the dead hair. But sometimes this process is disrupted. 

How do you know if there is a problem and what to do to prevent hair loss in the future or to regrow hair that has already been lost? In today’s article, we’ll look into whether red light therapy helps. Stay tuned for the best solution for hair growth.

What causes hair loss?

Severe hair loss can indicate a serious malfunction in the body. The scientific name for hair loss is alopecia. Two large groups can be distinguished because of the different causes that lead to alopecia:

Anagen alopecia — occurs due to exposure to drugs, chemicals, or radiation. The most striking example of this type of alopecia is complete hair loss while undergoing radiation or chemotherapy in oncology patients. After cessation of exposure to the factor causing the loss, the growth is restored. There is no specific treatment for it.

Telogenic alopecia — occurs under the influence of various diseases or conditions, and can be acute or chronic. The acute form can last for about six months and then go away, while the chronic form lasts for more than six months, in some cases — many years. 

Telogenic alopecia can also be divided into several groups depending on the causes. Androgenetic alopecia is the most common — it is typical for men and occurs in more than 90% of all cases. It is associated with a high sensitivity of hair follicles to male sex hormones.

Hair loss and baldness are terrifying for men and women alike. Many guys start losing their hair early because of a genetic predisposition. The causes of hair loss in young girls are more extensive:

  • Lack of nutrients as a result of following strict diets, in particular deficiencies of iron, zinc, and lysine;
  • Hormonal imbalance during puberty, after childbirth, during menopause, as a result of the failure of oral contraceptives;
  • Certain endocrine and chronic diseases;
  • Temperature exposure — refusal to wear hats in cold weather, frequent drying of hair with a hair dryer with hot air, regular use of styling devices;
  • Stress;
  • Long-term use of a particular group of drugs — antidepressants, hormonal pills, laxatives, diuretics, and others;
  • Frequent perms, use of aggressive hair dyes, improperly selected care products. 

How does red light therapy work for hair growth?

Red light therapy is effective in many cases. One such thing is therapy for hair growth. Red light therapy uses light wavelengths from 620 nm to 660 nm that penetrate the scalp to stimulate the metabolism of the hair follicles. As a result, more hair is formed. When you lose hair, you don’t lose the follicles, which are the tubular formations that attach hair to the skin. There is a hair follicle at the base of each follicle. This is where the hair begins to grow. If the hair follicle cells are not functioning properly, hair growth is prevented, causing hair loss.

Hair growth process
Hair growth process

When red light penetrates the base of the skin, it stimulates the cells, matrix, and papillae to produce more energy. This causes the cells to replicate successfully. The process allows new hair to grow. Thus, previously dormant follicles begin to grow. In addition, red light also helps stimulate the production of ATP. Individual cells in the hair follicle will increase activity because of the increase in ATP. This will speed up replication and restore energy to the cellular structures, allowing more keratin to be produced.

In addition to the above, red light therapy also increases collagen production. Although hair is mostly composed of keratin, collagen is an important protein because it acts as an antioxidant, fighting damage caused by free radicals. Since free radicals are responsible for damage to hair follicles, increasing the amount of collagen will help heal oxidative damage and accelerate hair growth in the shortest time possible.

How to use it for hair growth

In general, each device is slightly different, as are the rules for its use. But we will tell you the general principle now.

It is best to use the red light therapy device at a distance of 6-18 inches from your hair and skin for 10-15 minutes per session. It is best to repeat the treatment every day. Or at least five times a week. Most often the form of the device is a cap to put on your head, but there are others, such as a comb.

Best hair growth red light therapy devices 

Many devices on the market promise you to grow beautiful hair quickly and efficiently, but no one would say anything bad about themselves, right? It’s a jackpot to find the right one amongst all this variety. And we have collected three such jackpots for you, each of which is good in its way. All that is left is to choose one of them. 

Theradome Pro Laser Hair Growth Helmet — the deepest red light penetration

Technical Specs
Number of LEDs:80
Wavelengths:680 nm
Treatment Time:20 min session, 2x per week
Weight:672 gm

Pros

  • The most lightweight device on our list
  • The deepest penetration due to 680 nm wavelength
  • Runs on battery, no need to charge it
  • Has Voice Guidance
  • 6-month money-back guarantee

Cons

If you want a lightweight and comfortable device that helps make your hair stronger, grow more new hair, and stop baldness (all-in-one) — check out Theradome Pro Laser Hair Growth Helmet. It combines all these qualities and has helped thousands of people to regain their hair as in their youth. It stands out with the deepest red light penetration (680 nm) among the other devices on our list.

But don’t think it’s magic. First of all, it is persistence and consistency. You have to be prepared that it’s going to take a long time to get amazing results (sometimes years). The manufacturer claims that you will notice a decrease in hair loss after one or two months and the growth of new baby hairs after about the fifth month. But it takes a different amount of time for each person. One patient, for example, noticed improvements only after two years of continuous use but was nevertheless very pleased with the results.

In any case, Theradome Helmet will not complicate your life. Just two 20-minute sessions a week, during which you can watch TV, read a book, or do other things that interest you. Unlike with the Hairmax Comb Ultima 12 (review), here you don’t have to hold the helmet yourself, and you can trust it to do all the work.

Hairmax Laser Hair Growth Comb Ultima 12 — the fastest treatment time and budget-friendly

Technical Specs
Number of LEDs:12 medical-grade lasers (No LEDs)
Wavelengths:655 nm
Treatment Time:8 min session, 3x per week
Weight:1.2 kg

Pros

  • The fastest treatment time
  • The most budget-friendly option on the list
  • The most convenient portable device on our list
  • You can target the comb to treat a specific area

Cons

  • You will have to operate the comb yourself (when in helmets you can not care about the process)
  • If you have sensitive skin, Hairmax Comb may not fit you

If you enjoy the process of combing your hair and want to feel the work of the device while spending no more than 10-15 minutes, pay attention to Hairmax Laser Hair Growth Comb Ultima 12. This is the best handheld hair growth device you’ll ever experience (until they invent something new).

How is a hairbrush different from a helmet like Theradome Pro (review) or iRestore Laser (review)? The light from the lasers on the comb is more focused. Yes, the comb covers a smaller area of the head at a time, but this is compensated for by the focused light.

The HairMax laser comb is trustworthy at least because it is approved by 8 FDA certifications, 7 clinical trials, 14 international medical licenses, and 6 published medical journals. That’s a lot, isn’t it? Overall, the most important thing these studies have established is that the comb restores hair with an average increase of 15 extra hairs per square centimeter after six months of regular use.

Users especially often note that it’s handy and portable, and can be used at home or on the go. Charge lasts an average of 24 hours, and charging time is 2-3 hours. 

We have a separate article about Hairmax Laser Comb, so you can learn even more info about it.

iRestore Professional Laser Hair Growth System — The most lasers and LEDs to cover the largest area of head

Technical Specs
Number of LEDs:82 Medical-Grade Lasers and 200 Red Luminous LEDs
Wavelengths:650nm (Red Light)
Treatment Time:25 min session, 3-4x per week
Weight:900 gm

Pros

  • The most lasers (82) and LEDs (200) so that it covers the entire head area as much as possible
  • All the patients had positive results during clinical trials
  • It can be used with other treatments
  • Ergonomic design with 5 soft pads
  • It has a timer so you don’t have to time yourself
  • 6-month money-back guarantee

Cons

  • It’s a little pricey
  • One session takes 25 min (it’s more than with other devices on the list)

If you are hunting for a well-thought-out device that will do everything for your comfort and a great result — take the iRestore Professional Laser Hair Growth System

Here, it seems, they have thought of almost everything. The helmet will sit comfortably on your head due to the soft pads that adjust to the shape of your head. There’s a timer included so you don’t have to think about the time. In addition, this device has the most lasers and LEDs and will cover the entire surface of your head.

What we especially like is that all the patients in the clinical trials had positive results in one way or another. But, of course, it doesn’t all work overnight. At least 3-6 months of continuous use is usually enough to see the first results, but even then you need to keep going and not stop.

Be ready to spend 25 minutes of your time throughout the day — it’s a little more than Theradome Pro (review)  and Hairmax Comb Ultima 12 (review), but it still won’t bother you, since you can do something else in parallel during that time.

The science behind red light therapy for hair growth

Red light therapy is no longer a novelty; scientists have been researching it for decades. A wide variety of studies show the effects of light therapy on pain reduction, hair growth, and even weight loss. 

I will briefly tell you about several studies and their results.

For example, one study [1]  was conducted by six scientists, including Raymond J Lanzafame, Raymond R Blanche, and others in 2014. 41 men with androgenetic alopecia used red light laser and LED sources every day for 16 weeks. As a result, a 35% improvement in hair growth showed that light therapy works for these cases.

Another 2018 study [2] involved 100 people with AGA (Androgenetic alopecia). Each had one half of their head exposed to red light therapy and the other half only mimicked that light. The experiment was conducted for 24 weeks, three times a week for 30 minutes. After this treatment, significantly more hair coverage was observed on the LLLT-treated scalp than on the side treated with artificial light (14.2% vs. 11.8%). There was also a noticeable difference in hair structure —  those treated with the present treatment were firmer and thicker. There were no serious reactions in the patients, so this treatment can be considered safe and effective. 

One more general study [3] analyzed eleven other studies that relate to the effects of light therapy on hair growth. 680 patients (444 men and 236 women) participated in them. In the end, 9 of the 11 studies found significant results confirming faster and better hair growth with red light therapy, and 2 of the 4 studies also found that hair was thicker and stronger in both men and women.

Theradome Pro Laser Hair Growth Helmet

I bought this helmet three years ago and am absolutely satisfied with it. I am 52 years old and need help with baldness — and this is what I need. The hair is growing better. It’s very easy to use. 20 minutes a day and you are free. I put it on when I’m making breakfast and watching the news, so it doesn’t take extra time. By the way, it lasts a long time — 275 uses before replacement, and they change it quickly and have no problem either. I recommend it!

Katarzyna, PA

I tried different hair loss treatments and nothing worked, so I was skeptical about Theradome. But already after two months, I saw changes for the better. I hope to see my hair grow back soon.

Penny, CA

Hairmax Laser Hair Growth Comb Ultima 12

I am glad that the effectiveness of this product is confirmed by studies, it makes me more confident. So far I am satisfied with everything. I’ve been using it for a month now and I think my hair is falling out less.

I am 60 years old and needed help with hair loss due to menopause. I received this comb as a Christmas gift, and it’s one of my favorite gifts I’ve gotten in a while. I have recovered from my hair loss in 4 months and am seeing amazing results. I think I will be using it for a long time to come.

iRestore Professional Laser Hair Growth System

It took me a long time to choose which device to buy and I settled on the iRestore because it has the most lasers and LEDs (282). It is too early to talk about the results, but it is easy and convenient to use, plus the price is worth it. And I like the fact that it is in the shape of a helmet, and looks reliable. I hope to see positive results soon!

Debbie, SC

Incredible customer focus, comfort, and simplicity. Even though it’s not a cheap purchase, I didn’t hesitate long, because you have a 6-month return guarantee if something goes wrong. The employees of the company themselves contacted me and asked if everything was okay. This is the perfect device to start your way into light therapy — as simple and easy to use as possible. I’m already seeing good results and hope to grow out my hair like I did when I was young!

Seth, NJ

Side effects

Light therapy has many features, and one of them is the absence of side effects. This makes it a winning option compared to alternative methods of alopecia control, such as various treatments or hair transplants. 

The only things you might encounter (less than 5% of the cases) are the dry scalp, itching, irritation, or a feeling of warmth at the application site. But this is only in cases where your scalp is hypersensitive. For example, the effect of the sun on the scalp is much stronger than the effects of red and infrared light.

Side effects

Summary

The experience of thousands of users and clinical studies show that red light therapy helps to stop hair loss and grow it back. It’s not a quick process, it requires patience and persistence, but it’s worth it to see your hair healthy and beautiful again.
