KÉRASTASE Resistance Extentioniste Scalp & Hair Serum | Energizing Leave-In for Healthy Lengths

Targeted care from KÉRASTASE

The Kerastase Resistance Extentioniste Scalp & Hair Serum is a concentrated leave-in treatment designed to work through the scalp and the fiber to support longer, healthier-looking lengths. Infused with ceramides, it helps reinforce hair fibers from the root while promoting a calm, balanced scalp. The texture is soothing and non-greasy, making it easy to layer with your usual styling routine without weighing hair down.

Key benefits at a glance
