    TLDR Different patterns on the scalp help diagnose types of hair loss without needing a biopsy.
    In 2019, a study was conducted on 100 patients to examine the trichoscopic patterns of different types of nonscarring alopecia. The study found that yellow dots, black dots, and broken hairs were the most common features in alopecia areata, hair shaft diameter diversity was most common in telogen effluvium, and hair miniaturization was most common in androgenetic alopecia. The study concluded that trichoscopy, a noninvasive method, is a valuable tool for diagnosing and monitoring these conditions, helping to avoid biopsies and assess various stages and severity. The most sensitive diagnostic markers were yellow dots and short vellus hair, while the most specific markers were black dots, tapering hair, and broken hair. The study recommended the routine use of trichoscopy in the examination of nonscarring alopecia.

      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 visited a dermatologist for hair loss concerns and was prescribed a hair lotion called "Lotion revolotion evdermia," which is meant for hair toning, hydration, and anti-aging, not regrowth. The user found the dermatologist's behavior and the prescription to be questionable.
