    converts testosterone into a more potent androgen, dihydrotestosterone

    Steroid 5 Alpha-Reductase 1 (SRD5A1) is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen hormone. This enzyme plays a significant role in the development of male characteristics and is also implicated in conditions like androgenic alopecia (male pattern baldness) and benign prostatic hyperplasia.

      Dutasteride is associated with increased blood glucose, HbA1c, LDL cholesterol, and liver enzyme activity, potentially leading to diabetes, NAFLD, and liver metabolism changes. The conversation highlights concerns about these adverse effects and calls for more studies, including on finasteride.

      A 15-year-old is concerned about hair loss, possibly at Norwood 2 or 3, and is using shampoos and conditioners recommended by a trichologist. Suggestions include considering topical minoxidil and consulting a doctor about topical anti-DHT treatments like finasteride or RU58841, but avoiding 5-alpha-reductase inhibitors at this age.
