Renbow Crazy colour opens a new world of vibrant, exciting colours. Crazy colour cream is a conditioning temporary color. It is not recommended for clients with more than 10% white hair. For exotic, vibrant colors, the hair must be bleached to the light yellow stage and crazy color cream applied exactly as it is supplied, without the addition of any other substances. Crazy colour is an excellent medium for those who want to experience the mixing of primary, secondary and tertiary colours.
