Red Light Therapy for Hair Loss

Red light therapy is a safe, effective, and natural treatment option for hair loss that has been gaining popularity recently. Backed by a strong base of research, red light treatments have been shown to increase hair count, density, thickness, and strength for men and women alike. At Avanti Body in Vacaville, CA, we understand that hair loss can be embarrassing and even downright depressing, so we are excited to share this with you. In today’s post we’ll look at some of the research on red light therapy for hair loss. 

What Causes Hair Loss?

Hair loss can be brought about by a number of different factors including heredity, hormonal changes, medical conditions, and medications. Anyone can experience hair loss, but it’s more common in men. Baldness typically refers to excessive hair loss from the scalp, although it can affect any part of the body. Hereditary hair loss that occurs with aging is the most common cause of baldness. Known as androgenetic alopecia (AGA), it affects 50% of males by age 50 and 50% of females by age 80. When you hear the term male pattern baldness (or female pattern baldness), it refers to androgenetic alopecia. 

Red Light Therapy for Hair Loss

This 2014 study looked at 44 men with androgenetic alopecia. The participants in the study received red light therapy at 655 nanometers for 16 weeks—the study showed “significantly improved hair counts.”

Similarly, a 2017 systematic literature review found an “overall improvement in hair regrowth, thickness, and patient satisfaction following LLLT therapy.” The reviewers stated that it is a promising noninvasive alternative to surgical and medical therapy for hair loss. 

A 2018 randomized, double-blind study took 100 patients with AGA and gave each red light treatments on one-half of their scalps. The other side of their scalps were treated with sham (placebo) light therapy. After 24 weeks of treatment, the sides that were treated with RLT showed significantly greater hair coverage than the sham light-treated side. There was also a significant improvement in hair thickness, hair count, and hair coverage. 

A 2019 meta-analysis reviewed the results of 8 different studies that researched red light therapy for hair loss. “The quantitative analysis showed a significant increase in hair density for those treated by LLLT versus the placebo group.” This review found RLT to be an effective treatment for androgenetic alopecia in both men and women.
