    TLDR New treatments for alopecia areata show promise, but more research is needed to confirm their effectiveness.
    Alopecia Areata (AA) is a common type of non-scarring alopecia with no current preventive or curative treatment. It is caused by an aberrant immune response leading to premature transition of hair follicles from anagen to catagen and telogen phase. Treatments include topical and oral minoxidil, corticosteroids, and newer therapies like Janus kinase inhibitors. A study with 45 participants showed platelet-rich plasma was superior to triamcinolone acetonide in inducing hair growth, while another study with 19,218 patients showed that oral administration of low-dose minoxidil improved 18 to 82.4% of patients. However, further large-scale studies are needed to evaluate the efficacy of these treatments. Other treatments like Apremilast, Dupilumab, and Abatacept have varying degrees of efficacy. The document emphasizes the importance of shared decision-making between patients and healthcare providers in choosing the most suitable treatment option.

      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.
