Kerastase Resistance Bain De Force Architect Reconstructing Shampoo - 34 oz / liter - Rebuild Your Resilience, One Wash at a Time

Bring your hair back from the brink of breakage with the cult-favorite Kérastase Résistance Bain Force Architecte. This daily reconstructing shampoo is a targeted solution for weakened, brittle hair and those pesky split ends, working to fortify the fiber from the inside out. Designed for hair with an erosion level of 1-2, which means it’s perfect for that damaged, over-processed hair from heat-styling or chemical treatments. It provides a gentle yet effective cleanse, lifting away impurities without stripping your hair of its essential moisture. The result is hair that feels soft, supple, and much more resilient with every luxurious wash.

This powerhouse formula is engineered with the brand’s unique Vita-Ciment® Complex technology, an advanced blend of ingredients focused on rebuilding and protecting the hair structure. It features Pro-Keratin, a protein that works to simulate the function of natural keratin to effectively reinforce the interior of the hair fiber. This works hand-in-hand with Ceramides, which are crucial in recreating the intercellular cement, strengthening the hair fiber from deep within its core. Damaged hair is not only left feeling stronger but also gets a noticeable boost in shine and manageability.

For anyone who relies on heat tools or has colored their hair to the point of fragile dryness, this is the daily care that’s going to make a dramatic difference in hair health and texture. Beyond the Vita-Ciment® Complex, the formula also includes Resurrection Plant Sap, an ingredient well-known for its regenerating power, which further helps to smooth and hydrate even the most compromised strands. Say goodbye to that rough, brittle texture and hello to hair that’s visibly healthier, easier to comb, and protected against future damage and split ends. A little goes a long way, creating a rich lather that makes the investment entirely worth it for long-term fiber health.
