Kérastase

A rich deep purple masque that neutralises brassiness and unwanted yellow tones while deeply nourishing and restoring sensitised, lightened hair. This masque penetrates the hair fibre and reduces the unwanted yellow tones and leaves the hair with a cold nuance full of lustre.

Use:
Apply on washed and towel-dried hair onto lengths and ends. Leave-in for 5 minutes for light neutralisation or longer (up to 10 minutes) for stronger neutralisation. Add water, emulsify and rinse thoroughly.
