Hair dye L’Oreal Paris Excellence Creme 4.15 cold brown, permanent hair color, 50–60 ml per tube

L’Oreal Paris Excellence Creme 4.15 cold brown is a permanent hair colour formulated to deliver even, long-lasting pigment and integrated conditioning care. Designed for at-home or professional use, this permanent hair dye targets natural hair and grey coverage while shifting shade toward a cool brown tone. The kit is intended to be mixed with the supplied developer to activate the colour and achieve consistent results across hair lengths and types when application instructions are followed.

Advantages

The formula offers uniform colour distribution and enhanced grey coverage through a three-part system that combines pigment, developer, and protective care. Built-in conditioning agents help maintain hair softness and manageability after colouring. The shade 4.15 provides a cool brown result with neutral to slightly ashy undertones, suitable for users seeking a temperate brown finish. The permanent nature of the dye ensures durable colour retention and reduced fading with appropriate aftercare.

How to use

Prepare by reading the supplied leaflet and performing a skin allergy test 48 hours before application. Mix the colour cream with the developer as instructed in the kit until a consistent emulsion forms. Apply to dry, unwashed hair or follow the guidance for previously treated hair provided in the instructions. Distribute evenly from roots to ends or root-first for touch-ups, observing the recommended processing time for full development. Rinse thoroughly until water runs clear, then apply any included post-colour treatment to lock in colour and condition the hair.

Usage recommendations

For best results, follow the timing and mixing ratios supplied by the manufacturer, use a protective glove and towel, and perform a strand test if altering processing times. Maintain the cold brown tone with colour-safe shampoos and occasional conditioning treatments to prolong vibrancy and hair health.
