L'Oréal Professionnel INOA 4 Natural Brown Ammonia-Free Permanent Hair Colour 60g

Pure Natural Brown with Professional Grey Coverage

Classic brown shades never go out of style. L'Oréal Professionnel INOA 4 Natural Brown delivers a rich, balanced brunette tone designed for those who want natural-looking colour, impressive grey coverage, and exceptional shine without the strong smell associated with traditional hair colours.

Powered by L'Oréal Professionnel's revolutionary Oil Delivery System (ODS² Technology), INOA helps transport colour pigments deep into the hair fiber while respecting the scalp and hair structure. The ammonia-free formula provides a more comfortable colouring experience while leaving hair looking glossy, smooth, and healthy.

Whether you're covering grey hair, refreshing your natural brown shade, or maintaining salon-coloured hair, INOA 4 Natural Brown offers long-lasting professional colour results.
