How to use

Apply the 330 Strengthening Serum designed by Chanv to the scalp and the lengths when the hair is well dampened after the shower, or in the evening before bed. Use it twice a week for optimal results. Warm a few drops of serum in the palms of your hands, then gently massage the scalp to aid absorption. Let it work by wrapping your hair in a towel for 15 to 20 minutes, then rinse thoroughly with lukewarm water to avoid any greasy residue. It is recommended to apply the Serum to freshly washed hair so the nutrients penetrate more effectively.

Tips and tricks:

Targeted application for a healthy scalp: Concentrate the serum on the scalp to promote hair growth. Massage gently to spread the product evenly.

Intense hydration for the ends: Apply a few extra drops to the ends to prevent split ends and strengthen damaged hair. Ideal for dry or brittle hair.

Use before shampooing: Apply the serum before your weekly shampoo as a pre-wash treatment. Let it work for 15 to 20 minutes under a pre-warmed towel, then rinse and wash with the Chanv 330 Shampoo to remove any residue.

Do not overload: Avoid applying too much product so the hair is not weighed down. A few drops are enough to cover the whole scalp and the lengths.

    Excellent produit ! Je viens tout juste de me procurer ce sérum fortifiant pour cheveux. Même si je n'ai pas encore eu la chance de l'utiliser beaucoup, mes premières impressions sont très bonnes :)

    Mes cheveux sont très secs, cassants, très fins, clairsemés et sans tenue vraiment (suite de chimio et l'âge 75 ans) - je n'en suis qu'à mon 3e traitement mais j'aime bien la douceur ajoutée à mes cheveux.
