alopecia areata targetoid polycyclic concentric hair regrowth immunological recovery triamcinolone clobetasone zinc sulfate steroid injection topical steroid zinc supplement

TLDR A targetoid hair regrowth pattern indicates recovery in alopecia areata.

The study conducted at Baghdad Teaching Hospital observed a targetoid polycyclic concentric hair regrowth pattern in 7 male patients aged 4 to 25 years undergoing treatment for alopecia areata. This pattern, characterized by rings of hair growth alternating with rings of little or no hair growth, appeared 2 to 4 weeks after therapy with IM triamcinolone, topical clobetasone, and zinc sulfate. The targetoid pattern was considered a positive sign of immunological recovery, although its exact etiopathogenesis was not fully understood.
