L’Oréal Professionnel Inoa is an ammonia free permanent Professionnel hair colour that provides uncompromised comfort and rich, luscious colour. This new colour delivery mechanism uses mineral oil to act as the catalyst for depositing colour on the strands, which means it is gentler on the hair, and the scalp is also protected.

The hair can be lightened or darkened by 3 shades, and this revolutionary system even covers 100% of grey hair while leaving the hair feeling intensely nourished and hydrated with sublime shine.
