Ammonia-Free Permanent Hair Colour

L'Oréal Professionnel INOA 5.31/5GB Light Golden Ash Brown is a permanent cream colour formulated without ammonia. It uses ODS2 technology to deliver up to 100 percent white-hair coverage while lightening up to three levels in 35 minutes. The 60 g tube mixes in a one-to-one ratio with developer for straightforward application.

ODS2 Oil-Based Delivery System

The defining specification is the ODS2 oil-based delivery system that replaces ammonia with an alkaline agent suspended in oil. This mechanism drives pigments into the hair shaft while preserving the lipid barrier, leaving strands softer and more hydrated for up to six weeks after colouring. No other ammonia-free permanent colour in the range uses this exact oil-diffusion platform.

Professional Colourists Only

This product is intended for qualified hairdressers who understand oxidative colour chemistry, developer selection and processing times. Home users without formal training should not purchase it, as incorrect mixing or timing can cause uneven results or scalp irritation. Salons needing a non-ammonia alternative for sensitive clients will find it suitable.
