Background: Photobiomodulation therapy (PBMT) appears to be safe and effective for hair loss. Pulsed electromagnetic field therapy (PEMF) also has a positive biological effect on hair re-growth.
Objectives: We evaluated the efficacy and safety of both PBMT and PEMF for the treatment of androgenetic alopecia (AGA).
Materials and methods: This study was a 24-week, randomized, double-blind, sham device-controlled trial. We recruited 80 subjects with androgenetic alopecia. The subjects got treatment every week for the 1st 12 weeks, every other week for the next 8 weeks. PBMT entails 15-min therapy, and PEMF was carried out for 10 min.
