Kerastase Resistance Bain Extentioniste Length Strengthening Shampoo (8.5 oz) - Length Strengthened, Limits Extended

If you have ever felt defeated by hair that just will not grow past a certain, sad length-breaking off faster than you can trim it-it is time to hit the reset button. The Kérastase Résistance Bain Extentioniste is not just another shampoo; it is a foundational “hair training” program in a bottle, designed specifically to tackle hair that is weak, brittle, and prone to snapping before it can truly flourish. This formula transforms your daily wash into an act of deep fortification, creating the ideal environment from root to tip for long, strong, beautifully flowing lengths.

The true genius lies in its advanced formula, built around the powerful Creatine R Complex and enriched with Taurine. The Creatine R Complex is a smart fusion of Creatine, an amino acid that penetrates to reinforce the hair fiber’s internal structure, and Ceramides, restorative lipids that literally rebuild the hair’s surface. At the same time, Taurine, another amino acid, works at the scalp, stimulating and protecting the follicular environment to ensure that the new growth is healthy, strong, and prepared for its journey. This synergistic action delivers incredible results: hair is visibly protected against external stressors and its internal architecture is deeply strengthened, allowing you to chase those serious length goals without constant worry about fragility.

The sensory experience is exactly what you would expect from a luxury hair house; a generous, airy lather with a delicate, captivating aromatic fragrance that makes your shower feel like a salon ritual. Apply this strengthening “Bain” to wet hair, massaging well into the scalp to awaken the roots and then through the lengths to saturate every fiber with its reparative goodness. This essential first step in the Extentioniste routine immediately begins to improve elasticity and surface recovery, prepping your hair to receive the deep conditioning that follows. Say goodbye to the frustrating cycle of breakage and hello to a head of hair that finally feels as robust, shiny, and powerfully long as you have always dreamed.
