## Long description

Kérastase Resistance Bain Extentioniste Shampoo is a professional-grade hair care solution specifically formulated for weakened hair that is prone to breakage and split ends. This 250ml shampoo works to reinforce the hair fiber from the root to the tip, creating a stronger foundation for healthy hair growth. By gently cleansing the scalp and hair, it removes impurities while depositing essential nutrients that improve overall hair texture, resilience, and natural shine.
Advantages
The primary benefit of this shampoo is its ability to fortify the hair structure, making it significantly more resistant to mechanical damage and breakage. Regular use helps to seal the hair cuticle, which results in a smoother, more polished appearance and a reduction in the visibility of split ends. The formula is designed to support the hair's natural growth cycle by maintaining a healthy scalp environment, ensuring that hair remains strong as it lengthens. It provides a balanced cleanse that does not strip the hair of its necessary moisture, leaving it feeling soft, manageable, and revitalized after every wash.
Suitable for
Weakened hair prone to breakage
Individuals looking to grow longer, stronger hair
Hair with visible split ends
Daily maintenance for damaged hair fibers
When it may not be suitable
This product may not be the ideal choice for individuals with extremely oily scalps who require a deep-cleansing or clarifying shampoo, as its primary focus is on strengthening and repair rather than intense oil removal. Additionally, those with specific scalp conditions or sensitivities should consult the ingredient list before use.
