    TLDR Researchers developed a quick and accurate method to measure hormones in urine, confirming a baldness treatment's effectiveness without altering hormone levels.
    In 2019, researchers developed a method for simultaneously quantifying androgens and prostaglandins in human urine using ultra-high-performance liquid chromatography–tandem mass spectrometry. The method involved solid-phase and liquid–liquid extraction, enzyme hydrolysis, and chemical derivatization, allowing for separation and measurement of analytes within 22 minutes. The method was validated with high recoveries (81.0 to 102.9%), low limits of quantification (0.01 to 2 ng/mL), and good accuracy and precision. It was then applied to study the effects of a one-year finasteride treatment on male pattern baldness (MPB) patients compared to normal controls. The study found no significant difference in urinary androgen and prostaglandin levels between the two groups due to finasteride, confirming its effectiveness for MPB treatment. This mass spectrometry-based method also shows promise for evaluating androgens and prostaglandins in various inflammatory diseases.

      community Wouldn’t this nuclear stack make it almost impossible to lose hair?

      in Research/Science  66 upvotes 3 months ago
      The conversation discusses a hair loss treatment regimen involving dutasteride, pyrilutamide, oral minoxidil, and microneedling, with the aim of suppressing DHT and stimulating hair growth. Users debate the effectiveness and potential side effects of these treatments, noting that individual results may vary and that no treatment is foolproof.

      The conversation discusses the complexity of hair loss causes, suggesting that DHT sensitivity alone doesn't fully explain it. Treatments mentioned include finasteride and dutasteride.

      community Creatine is the opposite of minoxidil !

      in Research/Science  322 upvotes 2 weeks ago
      Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.

      community A concise, easy-to-understand post on Androgenic Alopecia theory and its practical applications

      in Research/Science  92 upvotes 3 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.
