New Koleston Perfect with ME+: The preeminent professional hair colour innovation in over 130 years. Koleston Perfect with ME+ is the first and only professional hair colour brand to feature breakthrough technologies, Pure Balance Technology and ME+, both proven to deliver vibrant, rich colour with less damage colour after colour, while ME+ reduces the risk of developing a new allergy to hair colour.

For people not allergic to hair colourants - although the risk of developing a new allergy is reduced, there remains a risk of allergic reaction that can be severe. Always perform an allergy alert test 48 hours before each colouration. Strictly follow safety instructions. If your client has ever experienced an allergic reaction to hair colourants, you should not colour. ME+ is present in specific shades of Pure Naturals, Rich Naturals, Vibrant Reds, Special Blonde, and Deep Browns of the Koleston Perfect brand.
