Designed to give a natural healthy shine through its unique formulation of ingredients. Hair Sheen is a perfect substitute for sebum (hair's natural conditioner) often missing in dry or stressed hair types. It will not make hair oily, but will create a protective film against constant exposure to the sun's damaging rays and other environmental pressures. Intensive helps to restore hair moisture instantly, whilst providing lasting style support from the very first wash. Intensive provides ongoing protection against the harmful effects of chemical treatments, thermal styling and environmental pressures.
