Key Ingredients & Technology

KM.RE.BOND Technology: KEVIN.MURPHY's KM.RE.BOND technology activates deep within the hair fibre to restore strength, repair damage and help protect against future stress. Hair looks and feels stronger, smoother and visibly healthier.

Arginine: Arginine works with the hair's natural keratin structure to help boost resilience and retain moisture. This helps keep hair supple, reduce breakage and support strength and smoothness during styling.

Fermented Oil Blend: A skincare-inspired blend of fermented Argan, Green Tea, Camellia Seed, Sunflower Seed and Sweet Almond oils. It provides lightweight, fast-absorbing nourishment to smooth frizz, refine texture, seal split ends and leave hair soft and shiny.

How to Use

• Apply 1-2 pumps of FLAWLESS to clean, towel-dried hair, concentrating on the mid-lengths and ends.
• Style as desired using heat tools or allow the hair to air-dry naturally.
