Improve you 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, more vulnerable hair. To help combat this, a cocktail of sulfur-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. Help boost your hair's strength and resilience, this protective formula also shields from UV damage to keep your hair and colour safeguarded. Directions of use Shake bottle well before opening Apply to lightly towel-dried, damp hair Pour a coin-size amount of product into palm, rub palms together then smooth throughout hair Comb through Do not rinse, style as usual Use daily or as needed May be used along with either Coconut or Carb Cocktail
