L'Oréal INOA is an ammonia-free professional hair colour product that provides an unbeatable level of comfort and rich, luscious colour. It uses an Oil Delivery System (ODS2) technology with a highly innovative oil base that optimises the action of the colouration system. This acts as a catalyst for depositing colour on the hair strands, creating a fantastic finish with the absence of ammonia meaning there are no unpleasant lingering odours.
