In 2010, LOréal Professionnel launched INOA, a revolutionary odorless, ammonia-free permanent hair color for optimized respect of the hair* and optimal scalp comfort. With INOA, L'Oréal Professionnel has created the Oil Delivery System (ODS), a breakthrough oil base that optimizes the effectiveness of the permanent hair color process. It means improved comfort for the scalp, better protection of the hair, and unlimited color results.
