CAIR. - Le Sérum Fortifiant


Strengthening serum

The health and beauty of your hair depends on your scalp. This exceptional detoxifying and fortifying hair serum, exceptionally rich in cutting-edge skincare active ingredients with proven action, is designed to stimulate the vitality of your scalp, redensify your hair and bring it health and radiance. Alcohol-free and enriched with pre-biome, it respects the microbiota and rebalances the natural ecosystem.

How do I use Fortifying Serum?

To promote the vital longevity of your hair, apply your Fortifying Serum before each shampoo. For a one-month intensive treatment, leave on overnight 1 or 2 times a week.

1) Apply fortifying serum directly to hair roots.

2) Soak entire scalp with directional detangling spray, lifting strands.

3) Gently massage to create a light emulsion with sebum to detoxify and optimize penetration of active ingredients into the superficial layers of the epidermis.

4) Leave on for 10 to 15 minutes, or overnight for an attack treatment. Rinse thoroughly and then shampoo.
