Abstract
Compositions for changing the color of hair by the action (direct or indirect) of compounds therein which release nascent oxygen, do less harm to the hair when they have a content of a water-soluble 3-amino-1-hydroxypropane-1,1-diphosphonic compound. The compound can be in free acid or water-soluble salt or partial ester form. Hair which is pre-treated with one of the mentioned diphosphonic compounds is at least partially protected against the action of nascent oxygen.
