    GlossarySerum Testosterone (Plasma Testosterone)

    measures testosterone levels in the blood

    Serum testosterone refers to the measurement of testosterone levels in the blood. This test, often called a Testosterone Blood Test or Total Testosterone (TT), is used to assess hormonal balance, diagnose conditions like hypogonadism or polycystic ovary syndrome (PCOS), and evaluate issues related to sexual development, fertility, and certain types of hair loss such as androgenetic alopecia.

      community Testosterone and hair loss seeming irrelevance

      in Research/Science  80 upvotes 2 years ago
      The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

      community Fats on your Head to Stop Hair Loss?

      in Research/Science  142 upvotes 2 years ago
      The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.
