Abstract
A method of conditioning and oxidatively dyeing human hair includes applying an oxidative hair dyeing composition to the human hair in order to dye the human hair and, simultaneously or subsequently to the applying of the oxidative hair dyeing composition, applying a particular hair conditioning composition to the hair. This hair conditioning composition has a pH value of from 3.4 to 3.9, which corresponds to an isoelectric point of the human hair, and contains from 0.001 to 2.5% by weight of a cationic polymer, an optional pH buffer and preferably additional conditioning ingredients, such as a cationic surfactant and/or a fatty alcohol.
