Benefits
Concentrated violet pigments counteract warm tones to reveal crisp platinum, icy ash, silver, or cool champagne shades.
Unlike drying purple shampoos, this rich mask deeply hydrates and restores elasticity to fragile, lightened hair.
Smooths down rough cuticles to tame flyaways, boost soft movement, and enhance brilliant light reflection.
Extends the life of your balayage, highlights, or platinum tint between major bleaching visits.
Your appointment
Hair is washed with a gentle clarifying shampoo to clear mineral buildup and open the cuticle for even pigment absorption.
The rich violet mask is evenly massaged through hair, carefully monitored for 5 to 15 minutes to achieve the precise target tone.
Once brassiness is neutralized, hair is thoroughly rinsed with cool water to lock in pigment and prepped with heat protectant.
