Ammonia-free permanent colour 5.1/5B

L'Oréal Inoa delivers a permanent hair colour in shade 5.1/5B without ammonia. The formula is designed for normal adult hair and aims to provide uniform and consistent coverage. It suits users who prefer a gentler colouring process without the strong odour associated with traditional ammonia-based dyes.

Oil-based delivery system

The oil-based technology replaces ammonia to drive pigments into the hair fibre. This approach reduces scalp discomfort and the characteristic chemical smell during application. The result is a more comfortable colouring experience while still achieving permanent, even results across the whole head.

Shade 5.1/5B coverage

The 2.1 unit covers a standard full-head application for average hair length and density. It handles complete grey coverage and consistent root-to-tip colour in a single use. It will not stretch to very long or extremely thick hair without a second pack.

Questions about this item

How often will the 5.1/5B shade need to be reapplied to cover regrowth?

Reapplication timing depends on individual hair growth speed; the permanent formula lasts until new growth appears.

What limits how long the 2.1 developer can process the colour in one session?

The developer strength determines maximum processing time; follow the included instructions for the 5.1/5B shade.

Does the ammonia-free formula reduce scalp warmth during the development period?

The ammonia-free oil-based system is designed to minimise strong odour and scalp discomfort while the colour processes.
