Les uv sont un traitement classique et parfois efficace de la pelade. Le tacrolimus (protopic) a été essayé dans cette indication, à ma connaissance sans succès pour l'instant.

Abstract
Eleven patients with alopecia areata affecting 10% to 75% of the scalp, average duration 6 years, had no terminal hair growth in response to tacrolimus ointment 0.1% applied twice daily for 24 weeks. Treatment failure may reflect insufficient depth of penetration of the ointment formulation and less than optimal patient selection.
