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.

Resistance-Extentioniste: The restorative treatment

As with most training programs, working with a coach to achieve your goals is the extra push needed to achieve visible results and keep you on track. The Extentioniste long hair-training program is a salon-exclusive service that will instantly reduce split ends by 78% and eliminate breakage up to 99% after just one application. By treating hair from root to tip, it allows hair to reach up to 4cm in 3 months with hair that is in optimal health throughout the lengths, allowing you to reach your long hair goals. Using a skincare-inspired layering technique, it pairs two professional-grade caring agents to foster a stimulated scalp environment to naturally strengthen the fiber starting at the root, then recover and reinforce hair along the lengths and ends.
