TLDR Dutasteride 0.5 mg is safe and effective for long-term use in Korean men with hair loss.

The study "Long‐term efficacy and safety of dutasteride 0.5 mg in Korean men with androgenetic alopecia: 5‐year data demonstrating clinical improvement with sustained efficacy" conducted a retrospective analysis on 99 male patients aged 18 and above suffering from androgenetic alopecia (AGA). These patients were treated with dutasteride 0.5 mg for at least 5 years from October 2009 to December 2016. The results showed that 89.9% (89/99) of the patients saw improvement, and 93.9% (93/99) experienced prevention of disease progression. According to the BASP classification, 52.5% (52/99) of the basic type, 75% (15/20) of the specific F type, and 82.2% (60/73) of the specific V type showed clinical improvement after 5 years of treatment. The study concluded that dutasteride demonstrated long-term safety and efficacy in Korean male patients with AGA over a period of at least 5 years.
