This Damage Undo Stop & Lock Treatment is a breakthrough in colour protection and colour longevity. It neutralises and eliminates excess hydrogen peroxide and blocks persulfates in the hair to prevent damage caused by over-processing and bleaching. Stop & Lock blocks the reaction between primary and secondary amines while neutralising the action of persulfates. It stops the effects of oxidation after hair colouring and bleaching processes, and closes the cuticle layers to seal in the oxidized colour molecules for longer-lasting colour results. The superior anti free-radical activity with complete neutralisation of heavy metals, assists with colour or bleach removal while improving the condition and shine of the hair structure from chemical aggression. Does not alter or modify the colour or bleaching results.

Key ingredients:
  • Hydrolysed Vegetable Protein: Has restructuring and volumising properties that strengthen the hair’s fibre
  • Polyamino Sugar Condensate: Offers maximum protection to the hair’s keratin structure while leaving a soft and healthy finish.
  • Aloe Vera: Soothes the scalp while hydrating and protecting hair
  • Panthenol: Prevents dehydration and brittleness on the scalp while reducing damage caused by chemical treatments and heat styling
