    TLDR Androgen levels increase with puberty and are linked to sexual hair development.
    The study measured serum androgens in 85 normal girls and 101 normal boys, observing changes across Tanner stages I to IV/V. In boys, testosterone and testosterone-like substances increased with puberty onset, with a more abrupt rise later, while dihydrotestosterone was higher in late puberty without a steep rise. Delta4-androstenedione showed no prepubertal increase, but dehydroepiandrosterone (DHEA) was significantly higher in children over 7 years. The most rapid DHEA increase occurred with pubic hair appearance (Stage II) in both sexes. In Tanner stages IV/V, androgen levels reached adult ranges except for DHT. In 22 girls with precocious adrenarche, androgen levels were higher than in prepubertal children but lower than in late pubertal girls, indicating a non-progressive disorder with early adrenal androgen maturation. A rise in all androgens correlated with sexual hair development.

      community Proof that finasteride messes with neurosteroids

      in Research/Science  230 upvotes 1 year 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.

      A 21-year-old experienced hormone changes after using self-made topical finasteride for hair loss, including a 20% decrease in DHT, a 47% increase in testosterone, and a 39% increase in estradiol. The user previously used minoxidil and microneedling but is now seeking ways to balance hormones, possibly through supplements or dosage adjustments.

      A user who has been trying various treatments for hair loss for four years, with no success. Suggestions include use of minoxidil, finasteride, RU58841, microneedling, supplements and multivitamins, lifestyle changes, scalp biopsy, and SMP.

      community I have been on finasteride for 9 months. (6 months on 0.25 mg, 3 months into 0.5 mg daily) here are the progress pictures.

      A user shared progress pictures after 9 months on finasteride, starting with 0.25 mg and increasing to 0.5 mg daily, noting improved hair density, especially at the crown, with initial side effects that resolved after the first month. The discussion includes user experiences with finasteride, concerns about side effects, and alternative treatments like rosemary oil and platelet-rich plasma therapy.

      The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.
