A gloss serum for coloured or highlighted hair that is in need of an injection of shine. Hair is left with an anti-frizz effect and long-lasting control, ultimate shine and suppleness. The innovative Color Freeze formula, consisting of lactic acid and calcium hydroxide, seals the hair surface and ensures that the colour pigments are fixed into the coloured or streaked hair. Natural light can be reflected evenly from the hair surface again. In addition, the BC Bonacure pH 4.5 Color Freeze products counteract the fading of hair colour. To use: Spread a small amount evenly into towel-dried hair. Then style.
