Kérastase Résistance Masque Extentioniste – Strengthening Hair Mask for Longer, Healthier Lengths

Available in Canada at Curious Salons

For
Fragile, breakage-prone, or slow-growing hair needing deep strengthening, improved elasticity, and smoother, healthier lengths from root to tip.

Description
A restorative pause for hair on its length-loving journey. Kérastase Résistance Masque Extentioniste is a luxurious, fibre-strengthening mask that fortifies fragile strands, improves resilience, and helps reduce breakage so you can grow your hair longer — with confidence. Its rich, velvety texture envelops each fibre, restoring softness, elasticity, and vitality while preparing the lengths for smoother, more consistent growth.

Formulated with the advanced Creatine R™ Complex, Ceramides, and restorative lipids, this mask works deep within the hair to reinforce structure, seal the cuticle, and protect from external stress. Perfect for lengths affected by heat styling, colouring, or Canada’s dry seasonal climate, it leaves the hair supple, strong, and beautifully nourished.
