675 nm laser treatment androgenetic alopecia hair shaft density yellow dots telangiectasias miniaturization process

Studysummary In this study, 675 nm laser treatment significantly improved hair density and reduced miniaturization in both male and female patients with alopecia androgenetica, showing promising results without side effects after 10 sessions. Our plain-language summary of this paper — not a Tressless recommendation.

The study assessed the efficacy of a 675 nm laser treatment for managing androgenetic alopecia in 17 subjects (6 women and 11 men) aged 18 to 65 years. The subjects, who had alopecia grades ranging from I-II in women and I-II-III in men, underwent 10 sessions of the laser treatment, each lasting 20 minutes. The results, verified at the third month of follow-up and at the end of treatment, showed a significant increase in hair shaft density and a reduction of yellow dots and telangiectasias characteristic of androgenetic alopecia. The 675 nm laser treatment resulted in a 60% reduction of the miniaturization process in the treated areas, with no side effects reported.
