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.
