    TLDR Minoxidil boosts enzymes that help hair growth.
    The study found that minoxidil increases the activity of 17β-hydroxysteroid dehydrogenase and 5α-reductase in human dermal papilla cells from balding scalp. These enzymes are involved in the conversion of testosterone to dihydrotestosterone, which is known to contribute to hair loss. The study suggests that minoxidil may work by increasing the activity of these enzymes, leading to increased hair growth. The study was conducted on cultured human dermal papilla cells from balding scalp, and further research is needed to clarify the role of 5α-reductase in male pattern baldness and whether the effect of minoxidil on testosterone metabolism is related to its therapeutic effect.

      in Research/Science  92 upvotes 2 years ago
      The mechanism of Androgenic Alopecia and practical applications of treatments like Minoxidil, Finasteride, RU58841, dermarolling, scalp massages, anti-fungals, progesterone, estrogen, PPAR-γ activators, reducing oxidative stress, and scalp exercises. It explains why DHT is important in AA and how other factors might be involved such as hypoxia, increased DKK-1 expression, morphological changes to the scalp, skull growth during childhood/puberty, and blood flow.

      Biotin is being misleadingly marketed as a primary treatment for androgenic alopecia, overshadowing more effective treatments like finasteride and minoxidil. There is a call for increased awareness and accountability to prevent misinformation.
