No ammonia & oxidants. Intended to refresh colour depth for treated hair. Lasts 4-8 shampoos. To achieve exotic, vibrant, semi-permanent colours hair must be porous or processed (such as bleached, tinted, permed or straightened) before application. Will part colour on untreated hair but it is recommended to have porous or processed hair before use to ensure vibrant and longer-lasting colour.
