Kerastase Resistance Extentioniste Hair Care Collection




Reset. Strengthen. Repeat.

The Extentioniste hair care 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.
The result, less split ends and hair breakage.
