ABSTRACT
Scalp psoriasis is associated with hair loss and an increased
telogen/anagen ratio. Topical treatment of scalp psoriasis (with
corticosteroids, dithranol or tar) results in decreased scaling, induration and
erythema of the plaques. Calcipotriol is effective in the treatment of
psoriasis vulgaris. However, the potent growth-inhibiting potential of this
compound might theoretically induce hair loss. A study was designed to find out
to what extent calcipotriol treatment modulates the percentage of anagen and
telogen hair during treatment of scalp psoriasis. A group of 26 patients
participated in a placebo-controlled dose-finding study on the efficacy of
calcipotriol in scalp psoriasis. Hair plucks before and after treatment were
taken. The telogen/anagen ratio remained unaffected during 6 weeks of
calcipotriol treatment. No correlation was demonstrated between efficacy of
treatment and quantification of telogen/anagen ratio. It can be concluded that
the growth-inhibiting potential of calcipotriol is not reflected in the in vivo
hair growth pattern during calcipotriol treatment. (AUTHOR)
