How does this shampoo rebuild and fortify weak hair?

The formula centers on a Pro-Keratine Complex that helps adhere to and reinforce the hair fiber, improving tensile strength and reducing fragility over repeated use. Gentle cleansing removes impurities while preserving necessary moisture for resilient strands.

• Pro-Keratine Complex supports fiber reconstruction and surface repair.
• Mild surfactants clean without stripping, keeping hair hydrated.
• Daily-use formulation suits routine maintenance of repaired hair.

What results can I expect after using the refill regularly?

With consistent use, hair appears less brittle and feels smoother, with improved combability and reduced breakage during styling. The shampoo establishes a foundation for further treatments like masks or serums to enhance long-term resilience.

• Reduced snap-off and split ends from strengthened fibers.
• Smoother surface for shinier-looking hair and easier detangling.
• Preparation of hair for follow-up treatments and styling products.

How should I use the KÉRASTASE Resistance refill for best effects?

Apply to wet hair, lather gently from roots to ends, then rinse thoroughly; repeat if needed. For maximum restoration, follow with a matching KÉRASTASE Resistance conditioner or mask to lock in benefits and enhance manageability.

• Wet hair thoroughly before applying a small amount to scalp and lengths.
• Massage to activate Pro-Keratine Complex, then rinse well.
• Pair with Resistance conditioners or treatments for deeper repair.

Is the refill format practical and environmentally friendly?

The 16.9 fl oz refill is designed to reduce plastic waste compared with standard single-use packaging, making it a convenient, cost-effective option for frequent users. The refill keeps the same salon-grade concentrate while simplifying storage and refill routines.

• Smaller, refill-friendly package lowers overall plastic consumption.
• Travel-friendly size that fits easily into bathroom storage.
• Same concentrated repair performance as the original bottle.
