Professional demi-permanent colour

L'Oreal Professionnel Dia Color 4/4N Brown is an alkaline demi-permanent gloss designed for salon use on normal adult hair. The ammonia-free formula deposits rich, deep reflects and covers up to 70% of grey hair. It works on natural or previously coloured bases at the same level for shiny, visible results. The 57 ml tube supplies a professional single application.

Ammonia-free alkaline system

Without ammonia the mixture has a milder odour and reduces scalp irritation during processing. Ionene G and Incell technology complex penetrate the fibre to strengthen and protect hair while colour develops. The gloss texture ensures even distribution from roots to ends without dripping. Professional expertise is required to select the correct developer and timing for each client.

Strengthening care complex included

The integrated Ionene G and Incell blend conditions the cuticle during the colour service, leaving hair feeling smoother and more resilient after rinsing. No separate treatment step is needed, which shortens the overall appointment time. The 1.7 oz format matches standard salon mixing ratios for consistent, repeatable outcomes.
