L'Oreal Professionnel INOA 1/1N Black Permanent Hair Color 2.1oz 60g

Ammonia-free permanent colour for full grey coverage

L'Oreal Professionnel INOA 1/1N Black uses ODS2 technology to deliver permanent colour without ammonia or odour. The 60 g tube mixes in a 1 to 1 ratio for straightforward preparation. It lightens natural hair up to three levels in 35 minutes while covering up to 100 percent of white hair. The formula leaves strands feeling intensely nourished, hydrated and softer than before colouring.

60 g tube handles complete regrowth touch-ups

A single 60 g tube provides enough mixture for a full-head application on normal hair, covering resistant white hair in one session. The 35 minute development window gives consistent lift up to three levels without extending processing time. Very long or exceptionally thick hair may require a second tube to ensure even saturation from root to tip.

Mixes 1 to 1 with dedicated developer for salon

The colour requires a matching oxidant mixed at equal volume, so the bowl and brush set must accommodate the combined quantity. No ammonia vapour means the salon stays odour-free during the 35 minute development. The creamy texture rinses cleanly, freeing the stylist from heavy residue removal and leaving hair with sublime shine until the next colour service.
