Abstract
(EN) The present invention provides a method of altering hair color comprising the steps of (a) applying a pretreatment composition, which has a pH in the range 1 to 13, to the hair to be colored, the pretreatment composition being substantially free of hair color altering agents; and(b) applying to the hair, in a subsequent step, a color altering composition which has a pH in the range 1 to 13, and the pH of the pretreatment composition is higher than the pH of the color altering composition; wherein the pretreatment composition is not rinsed from the hair prior to the application of the color altering composition.
