The Resistance Extentioniste range is designed to rebuild weak and damaged hair lengths while restoring the hair fiber. It is powered by Creatine R, an exclusive complex composed of Creatine, an amino acid that reinforces the internal structure of the hair fiber, and Ceramides, which strengthen hair, add shine, and provide moisture.

The Resistance Extentioniste range includes:

Extentioniste Shampoo - Supports healthy hair lengths, protects the hair fiber from external aggressors, and stimulates the scalp. Extentioniste Conditioner - Supports healthy hair lengths, easily detangles hair, and seals split ends. Extentioniste Mask - Strengthens and supports healthy hair lengths, easily detangles hair, and seals split ends. Extentioniste Thermique Blow Dry Primer - Reduces hair breakage from blow-drying, supports healthy hair lengths, seals split ends, and provides heat protection up to 450°F. Extentioniste Scalp & Hair Serum - Supports healthy hair lengths, has a soothing texture for itchy scalp, and provides essential nutrition for healthy hair.

The main difference between the Resistance Force Architecte, Extentioniste, and Therapiste ranges is the level and type of hair damage. Resistance Extentioniste is ideal for slow-growing, damaged hair lengths.

The key ingredient in the Resistance Extentioniste range is Creatine R, an exclusive complex that reinforces the internal structure of the hair fiber. This product is safe for color-treated hair.
