Hair dye L’Oreal Paris Casting Crème Gloss 3102 Cool Dark Brown

L’Oreal Paris Casting Crème Gloss 3102 Cool Dark Brown is an ammonia-free hair dye designed to give a natural-looking dark brown shade with a glossy, conditioned finish. The formula combines colour and gloss to refresh or darken hair tone while respecting hair fibre, and is suitable for users who want visible colour change without the intensity of strong permanent dyes. It provides partial grey coverage and an even, radiant result on natural or previously coloured hair.

Advantages

The product offers an ammonia-free formulation that reduces the characteristic odor of permanent dyes and helps maintain hair softness. The integrated conditioning gloss leaves hair with a shiny finish and manageable texture. The shade Cool Dark Brown delivers a natural, neutral-to-cool brown tone that blends with existing colour and reduces unwanted warm undertones. Application components are designed for home use, enabling an even deposit and consistent results when instructions are followed.

For best results, choose a shade close to your natural colour or the current base colour of your hair.
