Excimer laser therapy for hairline psoriasis: a useful addition to the scalp psoriasis treatment algorithm

Psoriasis is a chronic, inflammatory skin condition with negative impacts both physical and psychological. Scalp psoriasis, especially around the hairline, can cause significant impairment in quality of life due to its visibility. Options for treatment of facial psoriasis, including hairline involvement, are the use of low potency topical steroids, calcineurin inhibitors, and vitamin D analogues. Though the use of excimer laser for scalp psoriasis has been reported, there are no cases or studies specifically examining excimer laser phototherapy for the treatment of hairline psoriasis. We present a case of rapid improvement of hairline psoriasis using a regimen of 308 nm excimer laser with clobetasol spray and recommend an algorithm for the optimal treatment of scalp psoriasis utilizing currently available antipsoriatic therapies.
