Regrowing Hair Use Red Light Therapy

Getting Hair To Regrow

This study used two wavelengths of light,655 nm,and 780 nm.The light illuminated the scalp for 10 minutes once a day. After 14 weeks, the results were an increase in density to 145.1/cm2 vs. 137.3/cm2 pre-treatment.

Another study used a single light wavelength of 655 nm but used a combination of laser diodes and standard LEDs. Forty-two women completed the study. There were 24 women in the active group and 18 women in the sham group. The researchers counted the hair in a 2.85cm² area of the scalp. The baseline count in the sham group was 228. In the active group, the baseline count was 209. After 16 weeks of treatments, which consisted of one 25 minute treatment every other day, the hair count results for the sham group went from 228 to 252. For the active group, the hair count went from 209 to 31⁰².

That is an increase of 30% more hair for the actively treated group.

Evidence Suggests

Most clinical studies with hair regrowth used low-power lasers. However, evidence suggests that LEDs will work just as well. Modern LED caps use a combination of LED laser diodes and standard LEDs.
