Kerastase Fusio-Dose Booster Brilliance, 120ml

A transparent burgundy fluid that transforms the surface of the hair, reducing damage and making the fiber more uniform. Can be used after coloring or in between coloring. Can be mixed with any Fusio-Dose concentrate.

How to use: Open the Fusio-Dose concentrate ampoule and insert the booster into it. Turn the booster - about 20 ml of the booster composition will pour into the ampoule, the ampoule will be completely filled. Remove the booster from the ampoule and place the sprayer on the ampoule. Shake the resulting mixture thoroughly. The treatment is applied to damp, wrung-out hair after shampoo. Apply in strands along the entire length of the hair, spacing 2 cm from the roots. Does not require exposure - after application the composition is washed off with warm water.
