KÉRASTASE Sulfate-Free Repair Shampoo Refill 16.9 fl oz — Decalcifies & Strengthens Hair

KÉRASTASE Première Sulfate-Free Hair Repair Shampoo is a decalcifying, repair-focused cleanser that gently removes mineral buildup while strengthening over-processed or damaged hair.

This concentrated, sulfate-free refill shampoo is formulated to cleanse without stripping, targeting calcium and mineral deposits that make hair feel dull, stiff or prone to breakage. With citric acid as a key functional ingredient, the formula lifts buildup from the scalp and fiber surface while nourishing strands to restore manageability, shine and bounce. The refill size makes it convenient for regular use and reduces packaging waste compared with single-use bottles.

How does this shampoo remove buildup without harsh sulfates?

The gentle surfactants in this sulfate-free shampoo cleanse oils, styling residue and minerals without aggressive lather that can dry fragile hair. Citric acid helps dissolve calcium deposits and mineral films, while conditioning agents smooth the cuticle to reduce friction and frizz.

• Uses mild, non-stripping surfactants instead of sulfates.
• Citric acid works to decalcify scalp and strands for improved softness.
• Conditioning polymers help detangle and prevent further damage during rinse-out.

Will it help strengthen over-processed or chemically treated hair?

The formula targets weakened fiber by cleansing impurities that hide damage and by delivering reparative ingredients that reduce breakage during combing and styling. Regular use supports hair resilience and a smoother surface, which contributes to perceived strength and better styling results.

• Reduces friction and split-end stress with smoothing agents.
• Improves fiber elasticity to help resist breakage in damaged areas.
• Prepares hair for subsequent treatments by removing blocking buildup.

How should I use the refill for best results?

Pour the refill into your primary shampoo bottle or use directly in the shower if designed for that purpose; a little product goes a long way on wet hair. Work into the scalp and lengths, rinse thoroughly, and follow with a compatible conditioner or mask to maximize repair and hydration.

• Use a coin-sized amount on short hair, more for longer lengths.
• Massage into scalp for at least 30 seconds to lift mineral deposits.
• Pair with KÉRASTASE conditioners or a strengthening mask for best results.

Is this safe for color-treated or fragile hair?

Because it is formulated without sulfates and focuses on gentle decalcification and repair, this shampoo is suitable for many color-treated or fragile hair types. It removes buildup that can dull color while minimizing aggressive stripping; however, always patch-test if you have an extremely sensitive scalp or recent chemical processes.

• Sulfate-free cleansing helps preserve color tone and shine.
• Removes mineral film that can make color appear flat or uneven.
• Designed to be gentle on fragile, chemically treated fibers.

Who is this for: This refill is designed for anyone with over-processed, heat-damaged, chemically treated or mineral-affected hair seeking a gentle but effective cleanser that decalcifies and supports fiber repair. It’s a practical choice for users who want to maintain salon-level manageability, reduce breakage during daily styling, and extend the life of treatments and color while choosing a refill format to cut down on single-use packaging.
