KEVIN.MURPHY Leave-In Repair Keratin Leave-On Treatment 200 mL — Heat Protectant & Damaged Hair Repair

LEAVE-IN.REPAIR is a keratin-enriched leave-on treatment that rebuilds weakened hair fibers while adding lightweight shine and heat protection.

Designed by KEVIN.MURPHY, this salon-grade leave-in formula targets damaged, brittle, or chemically treated hair to restore strength and manageability without weighing strands down. It combines keratin proteins and protective ingredients to reduce breakage, enhance smoothness, and defend hair from heat styling up to 200°F / 93°C. The result is visibly healthier-looking hair that retains natural movement and gloss.

How does LEAVE-IN.REPAIR restore and strengthen fragile hair?

The formula delivers keratin proteins and fortifying agents that temporarily fill and reinforce the hair shaft, helping to reduce split ends and breakage. Regular use supports improved elasticity so strands resist snapping under tension.

• Keratin proteins to rebuild compromised fiber structure
• Protein blend that helps reduce mechanical damage
• Lightweight delivery that won’t make hair feel heavy or greasy

Will this product protect my hair during heat styling?

Yes — LEAVE-IN.REPAIR acts as a heat barrier for routine styling tools, shielding hair from temperatures up to 200°F / 93°C. It’s suitable to use before blow-drying, flat ironing, or curling to help minimize heat-related damage.

• Heat protection effective up to 200°F / 93°C
• Use on damp hair prior to applying thermal tools
• Helps maintain shine and reduces frizz after styling

How do I use this leave-in treatment for best results?

Apply a small, even amount to damp, towel-dried hair focusing on mid-lengths and ends; avoid the roots if you have fine hair. Comb through to distribute, then style as usual — it can be left in and reapplied as needed between washes.

• Work a pea-to-dime sized amount through short to medium hair; increase for longer hair
• Comb or brush to ensure even coverage
• Leave in — no rinsing required before heat styling

Is this product suitable for colored or chemically treated hair?

LEAVE-IN.REPAIR is formulated to be safe for use on color-treated and chemically processed hair, providing reinforcement without stripping or heavy buildup. Its sulfate- and paraben-free composition supports gentler maintenance of processed hair textures.

• Safe for color-treated and permed hair
• Sulfate- and paraben-free ingredients
• Cruelty-free formulation consistent with salon standards

Who is this for: KEVIN.MURPHY LEAVE-IN.REPAIR is ideal for anyone with weakened, dry, chemically processed, or heat-styled hair seeking an easy-to-use, leave-on treatment that strengthens strands, adds shine, and provides thermal protection without adding weight. It suits all hair types and works well in salon routines or at-home styling for clients who want healthier-looking hair with less breakage.
