Erbium YAG Laser in the Treatment of Androgenetic Alopecia

Abstract

The article presents data on the effectiveness of the 2940 nm wavelength erbium-doped yttrium aluminum garnet laser (Er:YAG) in the treatment of androgenetic alopecia (AA) in 85 men. All AA patients underwent a video trichodermatoscopy examination of the scalp using an Aramo-SG video camera (Korea) with ×60 and ×200 lenses, and the Trichoscience diagnostic program. The results of the study were evaluated by videotrichodermatoscopy by the presence of atrophied HF before and after 3 months of laser therapy. A 3-month erbium laser treatment using a 2940-nm Er:YAG laser along with the conventional therapy showed a high efficiency, which was expressed in a decrease in microfibrosis around the hair follicles and an increase in hair growth in the anagen stage.
