Summary

The goal of this clinical trial is to evaluate and explore the mechanism of 1565-nm non-ablative fractional laser in the treatment of alopecia areata. The main questions it aims to answer are: (a) comparing the secretion of various cells and cytokines around and within hair follicles before and after treatment; (b) determining the Lord Want effector cells with cytokines and demonstrating that they mediate involvement in correcting the immune immunity collapse process. Participants' 1/2 of the treated alopecia area was compared to their own other half of the untreated alopecia area, and they were followed every three months for efficacy assessment and scalp biopsy.
