Updated: April 2018. Seeing your hair go thinner and noticing those balding patterns grow bigger and bigger is an absolute horror for almost any man or woman, especially the young.
In our culture, there’s a tremendous shame about growing older, and losing your hair is a daily reminder that your body is changing.
What if I told you there’s a safer, natural (and possibly better) alternative for minoxidil, finasteride and hair transplants?
Can red light therapy (Low-Level Laser Therapy) reverse your hair loss?
Can it stop your hair from falling and regrow new, thicker hair?
Is it scientifically proven or just a myth?
What’s Red Light Therapy for Hair Loss?
Red light therapy, also known as cold laser, soft laser, and Low-Level Laser Therapy, is a safe form of light treatment that’s being used more and more to treat the genetic forms of hair loss (androgenetic alopecia or pattern balding) common in men and women over 35.
LLLT for hair loss uses LED devices which emit red light (wavelength 630-670 nm) available as:
- Laser hair growth helmets/caps – see the top 3 laser caps – reviewed and compared
- Hand-held devices – see the top 3 laser hair combs
- Red light therapy bulbs
What Does Red Light Therapy and How Does it Affect Your Hair?
First, let’s agree on some (disturbing) facts:
1. Men typically have a distinctive balding pattern involving hairline recession and vertex balding.
2. Women normally have a diffuse hair thinning over the tops of their scalps.
3. For both men and women, this feels horrible.
But here are the good news:
- Science has proven that Low-level laser therapy can be used in both men and women to treat androgenetic alopecia.
- Studies show that cold laser can regrow your hair on the top of your head/crown and along the forehead hairline
- Research proves that LLLT has no side effects, is painless, and safe.
- Improvement is reported after 12 to 26 weeks of use, with reduced hair fall and noticeable hair growth.
And here’s how it works:
The hair growth cycle consists of 3 phases:
1. Growth (anagen phase)
2. Resting (telogen phase)
3. Shedding (catagen phase)
Red light therapy was found to increase blood flow (microcirculation) in the scalp and stimulate metabolism in catagen or telogen follicles.
Accelerated production of anagen hair – new hair (stimulation of epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase).
I’ll bet now you may want to know:
Is this claim backed with scientific evidence? Is there proof?
The answer is YES!
Red Light Therapy for Hair Loss: Scientific Proof
As with all good things, this discovery was accidental:
In 1967, just a few years after the first working laser was invented, a Hungarian scientist wanted to test if laser radiation can cause cancer in mice.
He shaved their hair, divided them into two groups and gave a laser treatment with a low powered (694 nm) laser to one group.
The surprising results?
The mice did not develop cancer.
The hair on the treated group grew back much faster than the untreated group.
This was the first demonstration of laser “biostimulation”.
What about the latest studies?
This paper, published in the Lasers in Surgeries and Medicine Journal in 2013, has researched all clinical studies in PubMed and Google Scholar regarding hair loss and LLLT and concluded:
“Controlled clinical trials demonstrated that LLLT stimulated hair growth in both men and women. Among various mechanisms, the main mechanism is hypothesized to be stimulation of epidermal stem cells in the hair follicle bulge and shifting the follicles into anagen phase.”
Another paper, published in 2016, analyzed 11 studies, which investigated a total of 680 patients, consisting of 444 males and 236 females.
The results were extremely positive:
“Nine out of 11 studies assessing hair count/hair density found statistically significant improvements in both males and females following LLLT treatment.”
Additionally, hair thickness and tensile strength significantly improved in two out of four studies.
So now let’s get practical:
What’s the Right Wavelength for Regrowing Hair?
Through analyzing many studies, we found the best wavelength for hair regrowth to be 655nm.
Some studies achieved the same results by using devices in the range of 630 – 670 nm.
How Much does LLLT for Hair Growth Cost?
When I heard how much in-office hair lasers cost a year (about $4000), I almost fainted.
The good news is:
The home version of strong LED light (a real, screw-in red light therapy light bulb) is inexpensive and available to everybody.
So, you probably want to know:
☑️ The Best Home Laser Therapy Devices for Hair Regrowth
Here are the 3 Ways You Can Treat Your Hair Loss with LLLT at Home
1. A high-quality red light therapy bulb.
All you have to do is point the light to the problem areas on your scalp for 10 minutes (no longer!), 3 times a week.
2. The second option is a red light therapy comb, such as the HairMax Laser Comb.
This device requires time devoted to carefully moving the comb through the hair to allow laser penetration to the scalp.
The Laser Comb the only FDA cleared home LLLT device for the treatment of hair loss.
The results, as you can see in the reviews and ratings on Amazon, vary.
For some people it works, for others, it doesn’t.
3. The third option is a laser cap (helmet) for hair growth.
The 4 BEST laser helmets you’ll find HERE have been clinically shown to:
- Grow new hair
- Double the follicle diameter of existing hair (reverses miniaturization)
- Slow (and even stop) hair loss
When Can You Expect Results?
According to clinical studies, improvement is reported in at least some users after 12 to 26 weeks of use, with reduced hair fall and noticeable hair growth.
You have to be consistent and do not expect results in less than a month. For some people, it can take up to a year to see full potential results.
LLLT Possible Side Effects
While red light rays are proven safe and side-effect free, laser therapy should not be used if you are taking photosensitizing medication.
In this post, I’ve shown you the amazing ability of red light therapy in stopping hair loss and regrowing hair on the scalp.
Men and women with androgenetic alopecia, as well as people who have lost their hair due to chemotherapy, can benefit from this painless, noninvasive and safe way to regrow hair.
The benefits of LLLT for hair loss:
1. Can be used in both men and women
2. Noninvasive, painless, natural and safe
3. Home treatments are relatively inexpensive
4. Hair growth can occur on the top of the head and along the hairline of the forehead as well.
5. Visible results can be seen after 12 to 26 weeks of use.
