    TLDR The 675 nm laser treatment significantly increased hair density and reduced symptoms of androgenetic alopecia in both men and women, with no side effects.
    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.
