675 nm wavelength laser therapy androgenetic alopecia AGA terminal hair vellus hair laser therapy hair loss hair growth

Studysummary This study found that 675 nm laser treatment improved androgenetic alopecia in Indian patients, resulting in significant increases in hair count, density, and thickness after 14 sessions, enhancing the anagen phase and other hair-related parameters. Our plain-language summary of this paper — not a Tressless recommendation.

The study evaluated the efficacy of 675 nm wavelength laser therapy for treating androgenetic alopecia (AGA) in 20 Indian patients aged 23-57 years. Over 14 sessions, patients showed significant improvements in hair parameters, including a 17% increase in hair count and density, and a 13.91% increase in mean hair thickness. Both terminal and vellus hair counts and densities also significantly increased by approximately 17% and 16%, respectively. The findings suggest that 675 nm laser therapy effectively enhances hair growth and density in AGA patients.
