TLDR The best concentration of triamcinolone acetonide for treating alopecia areata is still unclear.

Alopecia areata (AA) is a chronic, non-scarring hair loss condition that can cause significant emotional distress. Intralesional corticosteroids, especially triamcinolone acetonide, are the primary treatment for adults with limited, patchy AA. However, the best concentration for these corticosteroids is still unclear. This manuscript reviews existing evidence to help guide clinical decisions regarding the optimal dilution of intralesional triamcinolone acetonide for treating AA.
