An Update in the Management of Alopecia Areata

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.
