KÉRASTASE Première Repair Pre-Shampoo Treatment Travel 1.5 fl oz — removes calcium buildup, strengthens keratin for less breakage

KÉRASTASE Première Repair Pre-Shampoo Treatment is a dual-action pre-wash formula that removes calcium buildup and reconnects weakened keratin links to reduce breakage and restore shine.

This travel-size 1.5 fl oz treatment targets persistent damage caused by mineral buildup from hard water while strengthening the hair fiber from within. Designed to be used before shampooing and then followed by the Première Repairing Shampoo, the formula combines citric acid to lift calcium deposits with glycine to support keratin bond reconnection. The result is smoother, more resilient hair with improved manageability and visible shine when used in a complete routine.

How does this pre-shampoo remove calcium buildup?

The treatment uses citric acid to gently dissolve mineral deposits that accumulate on the hair surface and contribute to stiffness and dullness. Instead of a harsh scrub, it acts chemically to lift calcium so the shampoo that follows can cleanse thoroughly.

• Citric acid targets calcium buildup without abrasive action
• Applied on damp hair before shampoo for targeted mineral removal
• Helps restore smoothness so light reflects better for more shine

In what way does it reconnect broken keratin links?

The formula includes glycine and other conditioning agents that support the reformation of weakened keratin bonds along the hair fiber. This bond-rebuilding action reduces the tendency of hair to snap and improves elasticity when incorporated into a routine.

• Glycine helps reconnect broken keratin links at the molecular level
• Strengthening effect reduces breakage during styling and brushing
• Designed to work best with the complementary Première shampoo for optimal repair

How do I use the treatment for best results?

Apply generously to damp hair before shampooing, from mid-lengths to ends, and massage through. Leave on for five minutes, do not rinse, then layer the Première Repairing Shampoo; emulsify and rinse to complete the protocol.

• Use on damp hair before any shampoo step
• Five-minute leave-on time maximizes actives’ contact with buildup and fibers
• Follow with Première Repairing Shampoo and routine conditioner for full benefits

What visible benefits can I expect and when?

With repeated use in the full Première system, the product claims up to 99% restoration of hair strength, reduced breakage, and increased shine compared to untreated hair. Individual results vary depending on hair condition and frequency of use, but many notice improved smoothness and manageability after a few applications.

• Targets stiffness and dullness caused by water minerals
• Helps reduce breakage during daily styling and washing
• Works as part of a system for best cumulative results

Who is this for: KÉRASTASE Première Repair Pre-Shampoo Treatment is suited for people with weakened, dull or brittle hair—especially those living in areas with hard water or who experience recurring stiffness and mineral buildup. It’s ideal for anyone seeking a targeted pre-wash step that combines mineral removal with bond-supporting ingredients, and it’s presented in a compact 1.5 fl oz travel size for convenient use at home or on the go.
