ClinConnect Summary

This clinical trial is looking at how a special type of laser treatment can help improve hair loss in people with darker skin tones (Fitzpatrick skin types V and VI). The study is open to healthy men and women aged 21 to 55 who have experienced mild to moderate hair loss for at least six months but less than five years. To join, participants should not have used any recent hair loss treatments or participated in similar studies. They should also be generally healthy and willing to attend all study visits.

If you decide to participate, you will receive laser treatment and be asked to follow some simple guidelines, like using specific hair care products and keeping your hairstyle consistent during the study. Additionally, you will need to attend appointments for evaluations, including taking some photos of your hair and scalp condition. This study aims to see if this laser treatment can make a positive difference for those facing hair loss in this specific group.
