TLDR 308-nm excimer laser therapy helps regrow hair in alopecia areata.
The study investigated the effectiveness of 308-nm excimer laser therapy on alopecia areata (AA) by treating one side of an alopecic patch in 10 patients over 12 weeks. Results showed objective improvements in hair count and diameter on the treated side, with a significant increase in hair diameter compared to the control side. The findings indicated that 308-nm excimer laser therapy had a therapeutic effect on AA, as confirmed by photographic and phototrichogram analyses.
