INOA15 — colour without compromise, even on grey hair

INOA works without ammonia and proves its worth on the most stubborn grey hair: even, natural-looking coverage with instant shine.

L'Oréal Professionnel

iNOA is a permanent hair colour without ammonia. Instead, the formula works with an oil: the Oil Delivery System carries the colour into the hair, with grey coverage of up to 100%. For grey hair there are the FUNDamental shades, which cover grey deeply and evenly. The colour has hardly any smell, which makes the treatment more pleasant than a classic ammonia colour, and the scalp stays comfortable. In the salon the colourist mixes the shade 1 to 1 with the iNOA oxidant, applies it to the roots and, where needed, to lengths and ends, and leaves it for 35 minutes. The hair is then carefully emulsified, rinsed thoroughly and finished with Metal Detox shampoo. The result is an even, natural-looking coverage with a shine you see straight away: grey hair that looks good instead of hidden.
