    GlossaryStratum Granulosum

    layer where skin cells start to die and form keratin

    The Stratum Granulosum, also known as the Granular Layer, is a thin layer of cells in the epidermis, the outermost part of the skin. It is situated between the Stratum Spinosum and the Stratum Corneum. In this layer, keratinocytes begin to die and form a waterproof barrier by producing keratin and lipids, which are essential for skin hydration and protection against external pathogens.

      The user has been on finasteride for 4.5 years and minoxidil for 10 years, maintaining hair but not regrowing much on the crown and temples. They are considering using a dermastamp more frequently and possibly trying RU58841, but are hesitant about dutasteride due to concerns about side effects and DHT suppression.

      community Tretinoin can make it worse!!!

      in Chat  7 upvotes 1 year ago
      Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
