Product Identity

L'Oreal Inoa 4.56/4RvR is a permanent hair colour in a 60g tube. The ammonia-free formula uses an oil-based delivery system to deposit Mahogany Red Brown pigment while covering up to 100% grey hair. It is designed for professional colour services on normal adult hair.

Professional Use Only

This product suits qualified colourists who want an ammonia-free permanent option with up to three levels of lift. It is not intended for home users without formal training, nor for anyone seeking a temporary or semi-permanent colour change. Buyers needing a non-oxidative formula should look elsewhere.

Shade Specification

The shade code 4.56/4RvR defines the exact Mahogany Red Brown result. This single identifier determines whether the tube matches the client's target colour and the required depth and tone. Always verify the code against the professional shade chart before mixing.

Questions about this item

What developer strength and mixing ratio does the 60 g Inoa 4.56/4RvR colour cream require?

The colour cream must be mixed 1:1 with a dedicated Inoa oxidant; the developer volume is chosen by the stylist based on the desired lift.

Can I apply this permanent shade over previously coloured or treated hair without unexpected results?

Inoa is ammonia-free and oil-enriched, but the manufacturer states it requires professional expertise; a strand test on the existing hair is the only reliable way to preview the outcome.

How can I verify the 4.56/4RvR Mahogany Red Brown shade has developed correctly after processing?

Rinse until the water runs clear, then check that grey coverage reaches 100 % and the tone shows the intended red-violet richness under natural light.
