Abstract
The present disclosure provides dye compositions comprising at least one hydrophobic direct dye with a logP of greater than 2, at least one organic or mineral acid with a pKa of less than 4.5, in an aqueous-alcoholic dyeing medium comprising at least 60% by weight of water relative to the total weight of the composition, the pH of the composition being less than 7. The compositions allow shades ranging from pastel to strong colorations to be obtained on keratin fibers. Furthermore, the coloration obtained makes it possible to achieve or even exceed the fastness of oxidation dyeing.
