Abstract
Disclosed are hair-colouring compositions comprising an oxidative dye and an alkalising agent consisting of isopropanolamine and a malic acid diester. The compositions according to the invention, due to synergic effects between isopropanolamine and the malic acid diester, are advantageous, because they lighten the hair by up to four levels, do not have an unpleasant odour, and limit the damage caused to the hair, maintaining its integrity and consequently its natural characteristics of elasticity, shine and combability.
