Clinical Trial Summary

Laser sources have established their potential effect in inducing hair regrowth. No study has compared the effect of ablative fractional 2940-nm erbium yttrium aluminum garnet (Er: YAG) laser and non-fractional 15650nm fractional laser in the treatment of androgenetic alopecia (AGA).


Clinical Trial Description

The investigators performed a prospective study between to compare the efficacy and safety of ablative fractional 2940-nm erbium yttrium aluminum garnet (Er: YAG) laser and non-fractional 15650nm fractional laser in the treatment of androgenetic alopecia (AGA). The efficacy of the two therapies was evaluated by the investigator's Global Assessment (IGA) scores and the patient's Likert satisfaction scale at week 12 and week 24. Changes in total, terminal and villous hair count, total and terminal hair diameter, and AGA grade were also recorded. Adverse events were evaluated at each follow-up. ;
