Scream Colour Gels contain vibrant, translucent colour that infuse the hair with bright exotic pigments that are ammonia-free. Scream Colour Gels transform the tint brush into a paintbrush with bold funky colours on light or bleached hair and softer, more subtle shades on virgin or darker hair. Scream is completely versatile and ignites the hair with colour and shine from a whisper to a scream.
