    Abstract:
    Studies on scalp hair from psoriatic lesions have revealed marked irregularities in the cuticular pattern. The aim of this study was to investigate the incidence of hair shaft disorders in psoriatic patients and to evaluate the possibility of a correlation with scalp involvement. We examined hair from 39 psoriatic patients using scanning electron microscopy and compared it with hair from a control group of 12 healthy people. We confined our observations of the hair fibres to the areas nearest the root. Our data confirm previous observations indicating that dystrophic changes in hair cuticle cells occur more often in hairs from both unaffected and affected skin of psoriatic patients compared with normal subjects. No differences were observed between hair shafts taken from affected and unaffected psoriatic areas; cuticular breakage and an abraded cuticular surface were present only in the hair of psoriatic patients.
