Kerastase Serum Extentioniste, Scalp & Hair Serum

Apply a maximum of 3 pipettes of Sérum Extentioniste along key sections of the scalp, once or twice a week. Using the pads of the fingers, work the Sérum into the scalp, using circular motions.

The Extentioniste routine targets roots, lengths and ends. It stimulates the scalp, then gently detangles lengths while reinforcing and finally sealing ends for hair that is as full and strong at the tips as it is at the root. Finish with the thermique and your hair is fortified with no split ends and no breakage.
