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

KÉRASTASE Première Sulfate-Free Hair Repair Shampoo is a decalcifying, repairing cleanser that gently removes mineral buildup and strengthens over-processed, damaged hair.

This sulfate-free shampoo is formulated to target hair weakened by chemical services, heat styling, and mineral buildup from hard water. It uses citric acid to decalcify the scalp and fiber, lifting residue without stripping, while conditioning agents help restore elasticity, reduce breakage and bring back shine and softness. The 16.9 fl oz refill format is designed for economical, low-waste replenishment of your favorite KÉRASTASE shampoo dispenser.

How does this shampoo clean without harsh sulfates?

Instead of strong sulfate detergents, this formula uses mild, sulfate-free surfactants that gently lift oils, pollution and mineral deposits. Citric acid helps dissolve calcium and other mineral residue that can make hair feel rough and lifeless.

• Mild surfactants clean without aggressive stripping
• Citric acid decalcifies hard-water buildup
• Designed to preserve color and moisture balance
• Suitable for daily or regular use on damaged hair

Will it actually reduce breakage and improve manageability?

The shampoo is formulated to strengthen fiber from the core and smooth cuticles, which helps lower mechanical breakage during brushing and styling. Regular use alongside KÉRASTASE treatments improves elasticity and makes hair easier to detangle.

• Strengthening agents help reinforce weakened sections
• Smoother cuticles reduce friction and tangles
• Restores bounce and natural movement over time
• Works best paired with a KÉRASTASE mask or leave-in

How should I use the refill to get the best results?

Pour the refill into your original KÉRASTASE bottle and use a coin-sized amount on wet hair, massaging into the scalp to lift buildup before rinsing. Follow with a compatible conditioner or mask for targeted rebuilding.

• Transfer refill into the brand bottle to avoid spills
• Massage scalp thoroughly to decalcify and cleanse
• Rinse and apply an appropriate conditioner or repair mask
• Use 1–3 times weekly or as needed with styling frequency

Is this refill suitable for all damaged hair types?

Yes — the gentle, strengthening formula is intended for chemically treated, heat-damaged, or environmentally stressed hair across textures. It focuses on removing mineral buildup and repairing fiber without harsh stripping, making it versatile for many concerns.

• Safe for color-treated and relaxed hair when used as directed
• Helps with damage from bleaching, heat and pollution
• Works on straight, wavy, curly and coily textures
• Refill packaging reduces plastic waste compared with buying new bottles
