Kérastase Resistance Sérum Extentioniste 50ml is a strengthening leave-in scalp and hair serum designed to support healthy hair growth lengths, reduce breakage, and reinforce the hair fiber from root to tip. Part of the Résistance Extentioniste range, this professional treatment is ideal for weak, brittle, or slow-growing hair that struggles with length retention.
Formulated with a powerful blend of Creatine R Complex and Maleic Acid, this serum helps strengthen the internal structure of the hair fiber while protecting it from daily damage caused by heat styling, brushing, and environmental stress. It works by reinforcing the scalp environment and fiber integrity, helping hair grow longer while staying stronger and healthier.
Unlike heavy oils or thick treatments, this serum has a lightweight, non-greasy texture that absorbs quickly into the scalp and hair without buildup. It helps improve elasticity, reduce breakage at the ends, and support overall hair resilience, making it especially beneficial for those trying to grow long, healthy hair.
With consistent use, hair appears stronger, smoother, and more resistant to snapping. It also helps improve combability and reduces mechanical damage during styling, which is one of the main causes of length loss.
