KEVIN.MURPHY Leave-In.Repair keratin leave-in treatment 200 mL — strengthens, reduces breakage & heat protection

LEAVE-IN.REPAIR is a lightweight keratin-based leave-in treatment that restores, strengthens and protects hair while adding glossy, manageable finish.

Designed by KEVIN.MURPHY to combine professional repair with everyday ease, this 200 mL leave-in formula uses targeted proteins to reinforce weakened strands, reduce breakage and smooth the cuticle. It doubles as a thermal shield for styling tools up to 200°F (93°C) and is free from sulphates and parabens, making it suitable for a wide range of hair types and color-treated hair.

How does this treatment rebuild damaged hair?

The product deposits keratin and reinforcing proteins to fill gaps in the hair fibre and improve tensile strength. Regular use reduces visible split ends and leaves hair feeling firmer without weighing it down.

• Keratin-enriched formula to strengthen strand structure
• Protein blend reduces hair breakage over time
• Lightweight emollients avoid heavy residue

Will this protect my hair during heat styling?

Yes — LEAVE-IN.REPAIR functions as a heat protectant up to 200°F (93°C), forming a protective layer that helps minimize heat-related surface damage during blow-drying and flat-ironing. It also improves combability so you spend less time with hot tools.

• Thermal protection rated up to 200°F / 93°C
• Enhances manageability for faster styling
• Helps maintain shine after heat exposure

How do I use it for best results?

Apply a small amount to towel-dried hair, focusing on mid-lengths and ends, then comb through to distribute evenly. You can leave it in—no rinse required—and proceed to air-dry or style with heat.

• Use on damp hair after cleansing and conditioning
• Concentrate on damaged or porous areas
• Reapply sparingly to dry ends between washes if needed

Is this product suitable for my hair type and color-treated hair?

Formulated to be lightweight and non-stripping, LEAVE-IN.REPAIR works on fine, medium and thick hair, including chemically treated or color-processed hair. Its sulphate- and paraben-free composition helps preserve color and integrity when used alongside regular color care routines.

• Safe for color-treated and chemically processed hair
• Non-greasy finish keeps volume in fine hair
• Cruelty-free formulation aligns with ethical routines
