How our colour-safe clean works 🫧​ ​ The secret is the pH. But why does pH matter? High pH swells the hair cuticle. When the cuticle is swollen it allows dye molecules to dissolve, degrade, and wash down the drain. It also leads to tangles and breakage. Keeping hair as close to its natural pH is the gentlest way to cleanse. . . #K18hair #K18hairscotland #hairdamage #peptideprep #biomimetic #hairscience #biomimetichairscience #K18results #K18peptide #K18treatment #hairrepair #heatdamage #splitends #phbalanced #hairdetox #hairrepairshampoo #veganhaircare #hairtreatments #hairstrength #veganbeauty #K18 #stronghair #haircare #healthyhair #bondrepair #warehouse5 #professionalhaircare #haircareexperts #hairstylists
