    GlossaryHedgehog signaling pathway (Hh pathway)

    regulates cell growth and development through protein-receptor interactions

    The Hedgehog signaling pathway is a crucial mechanism in developmental biology that regulates cell growth, differentiation, and tissue patterning. It involves the Hedgehog proteins binding to receptors on cell surfaces, which then trigger a cascade of intracellular events that influence gene expression. This pathway is essential for proper embryonic development and, when dysregulated, can lead to conditions such as cancer and congenital disorders.

      community Massive hair gains! Hope! May this post be a light to you in dark phases when all other lights go out

      in Progress Pictures  193 upvotes 1 year ago
      A 27-year-old man saw significant hair regrowth after starting a regimen in January that included topical minoxidil with finasteride, vitamins D and B12, fish oil, zinc with magnesium, quitting smoking, and intermittent fasting. People commented on the effectiveness of minoxidil in Southern populations and asked about the details and timeline of his treatment.

      community Topical finasteride now the safest possible path?

      in Finasteride/Dutasteride  84 upvotes 1 year ago
      Topical finasteride is considered a safer option for hair regrowth with fewer systemic side effects compared to oral finasteride. Some users report similar efficacy and side effects between topical and oral treatments, while others prefer topical due to reduced systemic exposure.

      community Alcohol-free minoxidil available in Europe

      in Minoxidil  5 upvotes 1 week ago
      Alcohol-free minoxidil options in Europe, particularly from a German pharmacy, are recommended for those with seborrheic dermatitis. Users suggest alternatives like Alopexy and Doppelherz foam, and emphasize avoiding propylene glycol and alcohol to reduce irritation.

      community Topical Dutasteride Seems to Work

      in Research/Science  22 upvotes 1 month ago
      Topical dutasteride, particularly at 0.05%, shows greater hair density improvement than oral finasteride over 24 weeks, though hair thickness gains are similar. Some users report side effects with topical treatments, but others find them effective for maintaining hair without significant systemic absorption.
