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. RESULTS ARE ACCELERATED AND ENHANCED WHEN HEAT FROM BLOW-DRYERS AND/OR STYLING APPLIANCES IS APPLIED.
