Improve hair's strength and condition with Color WOW's Kale Cocktail Bionic Tonic, a leave-in treatment that works to reinforce hair's internal bonds by over 50% in just one use.

When hair is colour-treated, the natural, internal cysteine bonds that keep strands strong and resilient are broken down, resulting in weakened, vulnerable hair. To help combat this, a cocktail of sulphur-rich Sea Kale, protein-building Amino Acids and B Vitamins work to help reinforce internal bonds and significantly reduce breakage after just one application; hair is left smooth, detangled and strengthened.

Helping to boost hair's strength and resilience, the protective formula also shields from UV damage to keep hair and colour safeguarded.
