    GlossaryAlopecia (Alopecic Patches)

    refers to hair loss from areas where hair normally grows

    Alopecia refers to the partial or complete loss of hair from areas of the body where it typically grows, most commonly the scalp. It can be caused by a variety of factors including genetics, autoimmune disorders, hormonal changes, and environmental influences. There are different types of alopecia, such as alopecia areata, which is an autoimmune condition where the immune system attacks hair follicles, leading to patchy hair loss.

      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.
