KEVIN.MURPHY Leave-In Repair keratin leave-in treatment 200 mL — Heat protectant & strengthening for damaged hair

KEVIN.MURPHY LEAVE-IN.REPAIR is a lightweight keratin-infused leave-in treatment that strengthens damaged hair, reduces breakage and provides heat protection up to 200°F (93°C).

Designed to restore elasticity and gloss without weighing hair down, this 200 mL repair serum blends protein-rich keratin with conditioning emollients to rebuild hair structure after chemical services, heat styling and everyday wear. It absorbs quickly, detangles, and leaves hair smoother and more manageable while maintaining a natural, touchable finish. Sulphate- and paraben-free, and cruelty-free, LEAVE-IN.REPAIR fits into salon routines or daily at-home care for all hair types.

How does LEAVE-IN.REPAIR rebuild and strengthen compromised hair?

The formula delivers keratin and supportive proteins to reinforce the hair shaft, helping to replenish lost strength and reduce the risk of future breakage. Conditioning agents smooth the cuticle so hair appears shinier and feels softer. Regular use improves resilience and manageability, especially after coloring or chemical treatments.

• Keratin proteins bond to weakened areas to support structure.
• Emollients smooth cuticle layers to minimize friction and split ends.
• Lightweight texture prevents buildup while delivering nutrients.

Can this product protect hair from heat styling?

Yes—LEAVE-IN.REPAIR functions as a heat protectant rated up to 200°F / 93°C, forming a protective layer that reduces thermal stress during blow-drying and flat-ironing. It helps maintain moisture balance so hair dries smoother and styles hold better. Apply evenly on damp hair before heat tools for best results.

• Heat protection barrier helps lower thermal damage risk.
• Improves styling performance and finish with less frizz.
• Use on damp hair prior to blow-drying or heat styling.

How should I use this leave-in treatment in my routine?

After shampooing and conditioning, towel-dry hair to remove excess water, then spray or apply a small amount from mid-lengths to ends and comb through. Style as usual—air-dry or use heat tools—without heavy residue. For very damaged hair, incorporate into daily or alternate-day routines for continuous repair support.

• Apply to towel-dried hair, focusing on mid-lengths and ends.
• Comb through to distribute product evenly before styling.
• Layer with styling products if needed; avoids weighing hair down.

What makes LEAVE-IN.REPAIR suitable for different hair types?

The formulation balances protein and moisture to suit fine hair needing strength without weight, and thicker hair needing replenishment and manageability. Because it’s sulphate- and paraben-free and cruelty-free, it pairs safely with color-treated, chemically relaxed or naturally textured hair. The lightweight finish preserves movement rather than creating stiffness.

• Light texture works on fine to coarse hair without greasiness.
• Safe for color-treated and chemically processed hair types.
• Cruelty-free formula aligns with conscious beauty choices.

Who is this for: KEVIN.MURPHY LEAVE-IN.REPAIR is aimed at anyone seeking targeted repair and protection—clients recovering from chemical services, frequent heat-stylers, and those with brittle or porous hair who want restored strength and shine without the weight of heavy oils. It’s also a practical upkeep product for stylists and at-home users who want salon-grade keratin benefits in a convenient leave-in format.
