    TLDR Dutasteride is safe and effective long-term for male hair loss.
    The study "Long-term efficacy and safety of dutasteride in Korean men with androgenetic alopecia: 5-year follow-up data exhibiting clinical improvement with sustained efficacy" investigated the 5-year efficacy and safety of dutasteride 0.5mg in 99 Korean men with androgenetic alopecia (AGA). After 5 years of treatment, 89.9% of patients showed improvement or prevention of disease progression, and 93.9% respectively. According to the basic and specific (BASP) classification, 52.5% of the basic type, 75% of the specific F type, and 83.3% of the specific V type showed improvement after 5 years of treatment with a decrease in the grades of the basic and/or specific type compared to baseline. The most common adverse events were sexual related symptoms within the first 6 months of the treatment period which subsided spontaneously. The study concluded that dutasteride exhibited long-term safety and efficacy in male AGA patients, with comparable outcomes to long-term studies evaluating the efficacy of finasteride in male AGA patients.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
