Alopecia areata in children: response to treatment with diphencyprone.

Abstract

Twelve children with extensive alopecia areata or alopecia totalis were treated with the contact allergen diphencyprone. The duration of treatment ranged from 5 months to 1 year. Eight of the 12 (67%) regrew scalp hair and in four (33%) there was a complete regrowth. Six months after treatment was discontinued three of the four children with complete regrowth maintained their hair, one had lost all the regrowth and a further child with patchy regrowth at the end of treatment subsequently regrew hair completely while off therapy.
