    GlossaryAutoimmune Response

    immune system mistakenly attacks body's own cells and tissues

    An autoimmune response occurs when the body's immune system mistakenly attacks its own cells and tissues, thinking they are foreign invaders. This can lead to various autoimmune diseases, such as alopecia areata, where the immune system targets hair follicles, resulting in hair loss.

      in Progress Pictures  492 upvotes 2 years ago
      A user who shared progress pictures of their scalp using a microscope camera, demonstrating the difference between healthy and miniaturized hair. Various explanations for the cause of this were discussed, such as DHT build-up in scalp sebum causing an autoimmune response leading to inflammation and eventual hair loss, with some suggesting a do-it-yourself treatment involving adding ascorbic acid powder to shampoo.

      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.
