How does red light therapy help in hair growth?

Red light therapy (RLT) is a non-invasive treatment that uses low-level red light in the 630-670 nanometers range to target specific areas of the body.

One of the most often applications of RLT is its ability to promote hair growth. This is because the red light energy stimulates the cells within the hair follicles, which in turn increases blood flow, metabolic activity, and ultimately, hair growth. 

The boost in cellular energy also results in increased production of adenosine triphosphate (ATP), the fuel that powers all of our cells, including those in the hair follicles.

Red light therapy can be delivered through various methods, such as handheld devices, full-body panels, and different caps. This makes it a convenient and accessible option for anyone looking to improve their hair growth and overall health. 

Moreover, RLT is completely safe and pain-free, making it an attractive alternative to more invasive hair growth treatments. With the convenience of at-home use, you can enjoy the benefits of this technology in the comfort of your own home.

Customer reviews

“I'm absolutely overjoyed that I chose to invest in the laser cap for my hair care routine. I make it a point to use the cap for 30 minutes every other day, as per the instructions, and it has proved to be very convenient and manageable. In addition to the laser cap, I also decided to purchase the hair vitamins and shampoo, which have worked wonders together.

It has been six months since I started using the laser cap and I can already see significant changes. The hair in my parting looks thicker, and there is less scalp visibility. I also find that I have more hair when I wash it, which is a great feeling.”

After using it for two years, I can confidently say that it has delivered on its promises. Not only has my hair thinning stopped, but I am hopeful that it will continue to work for me in the future.

I was also impressed with the customer service from Capillus. When I first received the cap, I realized that I needed a larger size. So I reached out to the company and they were extremely responsive and helpful. They quickly swapped out the cap for me, and the best part was that it was done at no additional cost.”

After careful consideration, I came across Capillus and was impressed with the scientific basis behind its claims. I took the leap of faith and invested in the product, and I’m so glad that I did. 

After using it for over a year now, I am proud to say that my hair has been restored to how it was when I was in my 20s. My hair is now long, thick, and full, and I have received numerous compliments from my friends, family, and even my hairstylist.”

Does red light therapy work for hair loss treatment? Based on scientific research

Red light therapy has been gaining popularity as a potential treatment for hair loss. Despite the growing interest, there is still a lot of debate surrounding its effectiveness for hair loss. Below, we'll take a closer look at the science behind red light therapy and what the research says about it.

A study [2] of 100 patients with androgenetic alopecia had participants randomly receive laser therapy on one side of their head and sham therapy on the other side, 3 times a week for 30 minutes over 24 weeks. Results showed the side treated with laser therapy had significantly more hair coverage and improved thickness compared to the side treated with sham therapylycopene-fortified.

The next study [3] consisted of 40 patients who were diagnosed with genetic hair loss and thinning and were randomly divided into two groups. The first group of 20 patients received real LLLT therapy, while the second group — a placebo system. 

The study lasted for 16 weeks, during which time both groups received three treatments per week. The results showed that the group receiving real LLLT therapy experienced an average increase in hair growth of 43%, while the group receiving the placebo only saw a 5% increase on average.

The following study [4] was conducted in private clinics with 128 male and 141 female participants who were randomized to receive either red light therapy or a sham device. The entire scalp of each patient was treated three times a week for 26 weeks. 

The results showed an average growth in hair count of 20.27 cm² from baseline after 26 weeks. The increase in hair density was not affected by the age or gender of the subjects. Additionally, 70% of patients who received red light therapy reported a reduction in overall hair loss. No serious side effects were reported during the trial.

The results of studies are promising and show that red light therapy can have a significant impact on androgenetic alopecia and thinning hair. In many cases, participants reported noticeable improvements in hair growth and coverage after just a few weeks of treatment.

Red light therapy may be a promising option for those looking to combat hair loss and promote hair growth.

How often to use red light therapy for hair growth?
