    TLDR Hormone levels change during puberty, leading to physical developments like pubic hair and voice changes.
    The study followed 43 boys over 4 years during puberty to analyze the changes in serum concentrations of various hormones. It found that dehydroepiandrosterone sulfate (DHAS) levels rose early in puberty, while progesterone (P) and androstenedione (A) increased later. Estrone (E1) levels reached adult levels by age 12, DHAS and estradiol (E2) by age 13, and dehydroepiandrosterone (DHA), P, 17-hydroxyprogesterone (17-OH-P), and A after age 15. Significant hormonal changes were associated with physical developments such as pubic hair, voice change, and genital growth, with testosterone levels increasing alongside these changes.

      The conversation is about choosing an additional topical treatment for hair loss, with options being fluridil, topical spiro, or alfatradiol, alongside existing treatments like dutasteride, oral minoxidil, latanoprost, and RU58841. Opinions vary on the effectiveness of adding these topicals, with some suggesting RU58841 is sufficient.

      The user shared their experience with hair loss treatments, including oral and topical Finasteride and Minoxidil, and detailed various blood test results to track hormonal changes. They noted that while DHT levels initially decreased with topical Finasteride, they later increased, but they observed positive results in hair growth.
