    TLDR Selective non-steroidal inhibitors of 5α-reductase type 1 can help treat DHT-related disorders.
    The enzyme 5 alpha-reductase (5 alpha R) catalyzed the conversion of testosterone into dihydrotestosterone (DHT), which was linked to conditions like benign prostatic hyperplasia, prostate cancer, acne, androgenetic alopecia in men, and hirsutism in women. Two isozymes, 5 alpha R-1 and 5 alpha R-2, were identified, each with distinct characteristics and tissue distributions, suggesting different roles in disease pathogenesis. The development of selective inhibitors for these isozymes, particularly non-steroidal inhibitors targeting 5 alpha R-1, was a significant focus in pharmaceutical research to create more specific treatments for DHT-related disorders. The paper reviewed major classes of these inhibitors and discussed biological tests for their efficacy.

      community Proof that finasteride messes with neurosteroids

      in Research/Science  230 upvotes 4 months ago
      Finasteride can impact neurosteroids, potentially causing depression and other side effects in some users. Despite these concerns, many continue using it for hair loss, with some switching to topical applications to mitigate side effects.

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      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.

      community Having androgen receptor density and sensitivity at wrong f*ing place

      in Satire  7 upvotes 1 month ago
      The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.
