Dermoscopy Study of Androgenic Alopecia in Men

    Bhavesh Songara, Bhavesh Astik, Hita H. Mehta
    TLDR Dermoscopy shows that varying hair shaft thickness and single hair follicles are main signs of male pattern baldness, especially in the fronto-temporal region.
    In a 2020 study involving 49 male patients with androgenic alopecia, dermoscopy revealed that hair shaft diameter variation was present in 88% of patients, single hair follicular units in 97%, and yellow dots in 38%, primarily in the fronto-temporal area. The most common stage of hair loss was Hamilton-Norwood Grade II, found in 40% of cases. The findings suggest that single hair follicular units and hair shaft diameter variation are key dermoscopic features for diagnosing and assessing androgenic alopecia, particularly in the fronto-temporal region.

      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.

      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.
