How Red Light Therapy Helps with Hair Loss

Hair loss

When your hair starts to fall, it is very normal for you to get paranoid and start a lot of new things to prevent baldness.

While there are multiple good options that might actually help you with hair loss, many people choose the wrong method and harm their hair health even more.

You need to choose only the proven and well-researched methods, like red light therapy. In this article, I am going to describe in detail how red light therapy helps with hair loss.

Scientific Evidence for Red Light Therapy

Before we get to discuss how red light therapy might prevent baldness, you need to understand why hair loss happens at the first place.

The most common reason behind hair loss is aging. According to statistics, over 50% of men above 40 suffer from hair-loss.

This percentage is even higher for women over 65, a rough 75% percent. It is called Androgenetic Alopecia.

Moreover, hair loss can happen due to genetic causes.

If your ancestors have suffered from the issue, you might also be a vulnerable to it as well. Bad hair and scalp health can contribute to hair fall too.

Red light therapy is considered as a natural and safe option to prevent and reverse hair loss.

Quite a few peers reviewed clinical studies, meta-analyses, and trials have provided evidence in favor of red light therapy.

In a meta-analysis from 209, 11 double-blind controlled trials were reviewed, for 8 clinical studies.

In this quantitative analysis, people who received red light therapy for hair loss showed positive results as their hair density increased.

In fact, red light therapy has shown better results than traditional hair fall treatment methods like placebo or sham.

The study has also proven that red light therapy works for both men and women who are looking for a hair loss remedy.

It is effective for both short term and long term results.

And most importantly, there was no reports of side-effects or health complexities. On the other hand, other methods like hair transplant very often comes with acute side effects and health complications.

How it Works

As now you have the scientific evidence proving how effective red light therapy for hair loss is, you might be interested to know how it works.

I will give a brief idea about the process behind red light therapy in this section.

When you apply red light therapy in any of your body parts, that part receives concentrated wavelengths of natural light.

There is no chemical, UV rays, or excessive heat is involved.

These wavelengths of light attempts to stimulate mitochondria of the cells where the therapy is applied. In short words, it replicates natural sunlight and increases circulation.

On the other hand, oxidative stress starts to reduce because of the light, preventing Androgenic Alopecia.

The whole process ensures that your body becomes able to produce more energy by itself, so that effects of aging can be prevented.

Other than keeping Androgenic Alopecia away, red light therapy can also speed up healing process, lower inflammation, reduce pain, and improve physical function.

Red light therapy benefits also include muscle recovery, enhanced endurance, and performance boost.

Result of Red Light Therapy Application

Almost all the studies conducted on red light therapy and it?s use on hair health have shown positive results.

Another meta-analysis took place back in 2017 which observed 680 patients under 11 studies.

These patients received red light therapy for hair loss problems.

Almost all of these individuals have reported significant improvement in hair density, hair thickness, hair count, and hair strength.

These are the common metrics that are used to determine hair health.

So it can be said that red light therapy improves all the aspects of your hair, and prevents baldness.

The patients were also asked about their personal experiences with red light therapy, and their responses were positive.
