How does this shampoo make hair look fuller?

The shampoo uses lightweight film-forming polymers that coat each strand, creating a fuller visual profile and smoother fiber surface. By improving the uniformity of the hair fiber, light reflects more evenly, contributing to a shinier, denser appearance.

• Polymers provide instant smoothing and light hold without stiffness.
• Improves fiber texture to reduce flat, limp areas.
• Visible body at the roots for a fuller silhouette.

Will it strengthen fragile or thinning hair?

KÉRASTASE Densifique Densité combines hyaluronic acid with ingredients that boost resilience along the hair shaft, reducing the appearance of breakage and improving manageability. Regular use enhances tensile strength so hair feels firmer and easier to style.

• Hyaluronic acid helps hydrate the fiber for improved elasticity.
• Nourishing agents support structural integrity from root to tip.
• Reduces friction during styling to minimize mechanical damage.

How does it handle scalp and product buildup?

The cleanser is formulated to remove residue and impurities thoroughly while being gentle on the scalp, leaving hair refreshed without stripping essential moisture. It provides a clean foundation that lets follow-up treatments or styling products perform better.

• Deep-cleansing action lifts oils and environmental buildup.
• Maintains scalp comfort and natural moisture balance.
• Prepares hair for conditioners, serums, and styling products.

What should I expect from the bottle and sustainability features?
