Damage Undo Stop & Lock Colour Preserver

Long-lasting colour and hair protection with an estimated 53% certifiably tested improvement in colour longevity. Protect colour intensity and vibrancy after a service by limiting fading and lightening, making colour last longer with brighter tones, and ensuring better, stronger hair. Hair colour quickly changes and fades after a service. Colours look lighter and less vibrant, and hair sees increased damage. That’s because hair continues to process long after a service. Hydrogen peroxide (inside developer) and amines (inside colour cream) or persulfates (inside bleach) causes a chain reaction that only finishes when all oxygen molecules are consumed. It’s hard to stop this reaction because oxygen is everywhere in the air and water we are exposed to! Using a traditional post-colour shampoo or mask does not solve the issue, because just closing the cuticles does not extinguish oxygen molecules inside the hair shafts. Colour turns lighter and loses its intensity very quickly, and blondes looks yellowish just a few hours after colouring or bleaching application. Stop & Lock Colour Preserver completely neutralizes hydrogen peroxide, stops oxidation and blocks persulfates. This results in long-lasting colour, less discoloration like yellowing, and better protected and healthier hair. See below for a more detailed breakdown.
