Redken Acidic Bonding Concentrate pH Sealer 250ml

A lightweight acidic spray that seals and smooths the hair after colour, lightening or chemical services. Redken's Acidic pH Sealer brings hair back to its natural acidic pH of 3.0 to 4.0, closing the cuticle so colour lasts longer and hair feels softer, shinier and stronger.

Part of the Acidic Bonding Concentrate range, it is the at-home step your stylist uses at the basin to finish a colour service.

How to use: after shampooing, spray evenly through damp hair from roots to ends. Leave for 1 minute, rinse, then follow with conditioner.
