Designed to minimize the formation of free radicals during the color formation by deactivating impurities like metals present in hair. Free radicals interfere with the color formation during the color development and are a key cause to hair damage.

With Pure Balance Technology, the result is even pure color results with natural depth and shine and significantly less hair damage, color after color.

A scientific breakthrough designed to replace extreme sensitizers, PPD and PTD, reducing the risk of developing a new allergy to hair color*. First patented in the 19th century, PPD and PTD had been the leading ingredients in permanent hair color for over 130 years.
