KÉRASTASE Resistance Force Architecte Shampoo — 16.9 fl oz Rebuilding Shampoo for Damaged Hair, Smoothes & Strengthens

KÉRASTASE Resistance Force Architecte Shampoo is a rebuilding shampoo that gently cleanses and reinforces weakened, damaged hair fibers so strands feel smoother, stronger and visibly shinier.

This concentrated salon-formula uses the brand's Vita-Ciment® Complex to target fragile, split or chemically stressed hair. It removes dirt and product buildup while replenishing the fiber structure, helping hair resist breakage from brushing and styling. The creamy lather leaves hair manageable and luminous without stripping moisture, so finishing routines deliver better-looking results.

How does this shampoo repair weakened hair fibers?

The formula deposits rebuilding ingredients that penetrate the cortex to help reconnect and fortify the internal hair structure. Over successive washes, hair feels less fragile and exhibits fewer visible split ends and surface roughness.

• Vita-Ciment® Complex helps restore internal fiber cohesion
• Cleanses without over-drying to preserve natural moisture
• Reduces surface porosity for a smoother cuticle appearance

Will it make my hair shinier and easier to style?

Yes—by smoothing the hair surface and improving fiber alignment, the shampoo contributes to increased shine and slip. That smoother foundation makes detangling and heat-styling more predictable and efficient.

• Softening agents leave hair touchably smooth
• Light-reflective finish enhances natural shine
• Improved manageability reduces frizz during styling

How do I use it for best results at home?

Apply to wet hair, lather gently from roots to ends, then rinse thoroughly; repeat if hair is heavily soiled. Follow with a compatible KÉRASTASE Resistance conditioner or mask to complete the rebuilding routine.

• Use 1–3 pumps depending on hair length and thickness
• Massage into scalp for a clean base and through lengths for fiber care
• Pair with Resistance treatments for improved cumulative benefits

Is this shampoo suitable for chemically treated or color-treated hair?

Formulated for damaged and stressed hair, it is compatible with many color and chemical services, since it focuses on fiber repair and gentle cleansing. For color preservation, pair it with a color-protecting conditioner if needed.

• Safe for hair weakened by bleaching, coloring, or thermal styling
• Helps reinforce fragile strands after chemical processes
• Works best alongside salon-recommended KÉRASTASE post-service products
