Koleston Perfect is the first professional hair color brand to feature breakthrough technologies boasting:

Wella Professionals technical advancement soars to new heights with the introduction of Koleston Perfect with ME+. It is the first and only professional hair color brand to feature breakthrough technologies, Pure Balance Technology and ME+.

The Pure Balance Technology is 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.

• Meanwhile, the ME+ technology is a scientific breakthrough designed to replace extreme sensitizers, PPD and PTD. ME+ considerably reduces 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. NEW KOLESTON PERFECT with ME+ is about to change that, offering salon clients our most meaningful change in hair color innovation in over a century.

• The new formula also delivers color that is significantly more even, balanced and true to tone from root to tip offering better balance of tone and control of depth with up to 100% grey coverage. The vibrant color portfolio spans naturals, brunettes, reds and blondes, plus a special mixing range to make a wide array of shades possible.
