TLDR Low-level laser therapy may increase hair density in pattern hair loss.
The document discusses the potential effectiveness of low-level laser therapy (LLLT) as a treatment for androgenic alopecia in both men and women, either as a standalone treatment or in conjunction with other therapies. It acknowledges that LLLT is a promising treatment for hair loss but also highlights that further research is needed to determine the optimal parameters for its use. The document references a study by Jimenez et al. as the most comprehensive to date, which found a statistically significant increase in terminal hair density in subjects treated with a lasercomb at 655 nm wavelength compared to a sham treatment. This study supports the efficacy of LLLT at this wavelength for treating pattern hair loss. The document also notes that the study by Munck et al. included global evaluation, which is an important measure of visible changes in hair density, and that their results were consistent with those found in other objective studies.
