Summary

This study tested whether a laser treatment used for skin rejuvenation could help grow hair in people with alopecia (hair loss) on the scalp. Only 5 people were enrolled before the study was stopped early. Each person had half their scalp treated with a laser and the other half left alone for comparison. The goal was to see if the treated area grew more hair.
