Extentioniste Routine

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.
