    TLDR A method was found to visualize hair regrowth and avoid unnecessary side effects from treatments.
    The document discussed a method to visualize the regrowth of white vellus hairs using superficial cryotherapy. It highlighted that intralesional corticosteroids were the preferred treatment for adults with localized alopecia areata, despite the lack of randomized controlled trials. Hair regrowth was observed in approximately 64-97% of patients with patchy alopecia areata treated with 2.5-10 mg/mL triamcinolone acetonide. The method aimed to provide evidence of hair growth to avoid unnecessary side effects from repeated treatments, such as transient atrophy and telangiectasia.

      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.

      People are discussing why some choose finasteride over dutasteride for hair loss, noting that while dutasteride is more effective, it's also more expensive, less researched, and potentially has more side effects. Some users shared personal experiences with side effects from both drugs, and others mentioned that finasteride is FDA approved for hair loss, while dutasteride is not, except in Japan.
