Alopecia Areata: A Non-Scarring, Multifocal Hair Growth Disorder

    Kerstin Foitzik‐Lau
    TLDR Alopecia areata causes patchy hair loss and has no cure, but treatments like corticosteroids and minoxidil can help.
    Alopecia areata was described as a non-scarring, multifocal hair growth disorder characterized by patchy hair loss that could occur on any hair-bearing site of the body, potentially leading to complete baldness. It was believed to be an autoimmune disease with a genetic basis and environmental triggers. Treatments often involved immunosuppressing or immunomodulating agents, which had variable effectiveness, but there were no cures or methods to prevent relapses. Common treatments included corticosteroids, topical sensitizers, and minoxidil.

      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.
