Apply the purple shampoo to wet hair and leave on for at least 2 minutes.The application time can also be longer depending on how intense are the unwanted tones to correct.After the application time, rinse thoroughly.We recommend using the shampoo in the Kérastase Blond Absolu system with conditioner, mask and leave-in.
Furthermore, Kerastase Blond Absolu Bain ultra-violet contains hyaluronic acid and edelweiss extract, which strengthens the hair fibre from within, stimulates scalp renewal, thus preventing future hair loss.Edelweiss soothes the hair fibre sensitised by colouring and bleaching and improves hair elasticity and resistance.
Mask or conditioner should be chosen according to the desired level of colour correction.
