    protects against external threats and prevents water loss

    The Skin Barrier Function, also known as the Epidermal Barrier Function, refers to the skin's ability to protect the body from external threats like pathogens, chemicals, and physical injuries, while also preventing excessive water loss. This function is primarily carried out by the outermost layer of the skin, the stratum corneum, which consists of tightly packed dead skin cells and lipids that form a protective barrier.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community Topical finasteride now the safest possible path?

      in Finasteride/Dutasteride  82 upvotes 5 months 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.
