    TLDR Dutasteride improved both hair loss and acne in two young men.
    The study reported dual effects of the 5α-reductase inhibitor dutasteride on androgenetic alopecia (AGA) and acne vulgaris in two male patients. Both patients, aged 26 and 23, were treated with dutasteride (0.5 mg/day) for AGA and experienced significant improvement in their acne vulgaris without the use of antibiotics or anti-acne creams. Dutasteride, which inhibits both type I and type II 5α-reductase enzymes, was shown to be effective in reducing dihydrotestosterone (DHT) levels, thereby improving both conditions. The findings suggested that dutasteride could be a novel treatment option for male patients with concurrent AGA and acne vulgaris, although it should not be used for treating acne in female patients, especially before menopause.

      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.

      Dutasteride raises scalp testosterone by 99%, which may not be ideal for those sensitive to all androgens. Some argue finasteride's balancing act might be better, while others believe dutasteride is superior for hair regrowth.

      The conversation discusses hair loss treatments, with some users advocating for finasteride and minoxidil, while others express concerns about potential side effects of finasteride. A social media influencer is criticized for promoting scalp massages and minoxidil over finasteride, which some believe is misinformation.
