Question about Wella Professional - Koleston Perfect Meâ"¢+ Pure Naturals - Permanent Hair Colour 4/00

Wella Koleston Perfect does not contain PPD (paraphenylenediamine). It uses ME+ technology, which is a permanent oxidative colouring molecule that replaces PPD and reduces the risk of developing a new allergy to hair dyes, while offering unequalled colouring results.
