ABSTRACT:
Hair on a live head is treated with metal ion in a pretreatment step then subjected to an oxidative or autooxidative dyeing step in which scalp staining occurs. Between the pretreatment step and the dyeing step the scalp of the live head is subjected to vigorous massage, rubbing, combing or brushing for a time sufficient to reduce scalp staining, or sufficient time is permitted to elapse between the pretreatment step of the dyeing step to reduce scalp staining, or a combination of these two procedures is employed.
