Subrina Professional Permanent Hair Colour – Colour with Dimension and Shine 4/00 | Essential Range

The colour locks in with confidence… and the brown achieves cool definition and absolute control. Subrina Professional Permanent Hair Colour 4/00 Intense Medium Brown Natural Cool has been developed to meet the most demanding situations - especially when the goal is to cover resistant grey hair without sacrificing naturalness or chromatic balance.

The permanent colour penetrates deeply thanks to liquid crystal technology, which locks pigments deep within the hair fibre, ensuring uniform, intense, and long-lasting colour. The result is an intense medium brown, with a cool and stable tone, that enhances natural cool undertones when colouring grey hair and effectively neutralises unwanted yellow tones.

Part of the Essential range, the Natural Cool 4/00 tone has been formulated for maximum performance on stubborn grey hair. Its high pigment concentration ensures optimal coverage of resistant grey hair, providing a homogeneous finish even in the most critical areas. Due to this enhanced grey coverage, the final result may appear half a shade darker - a technical effect that is expected, controlled, and valued in a professional setting.

The Emulsion system boosts oil deposition, improves pigment penetration, and reinforces the formula's conditioning properties. Hair remains disciplined, with professional shine and a well-cared-for texture, even in ammonia-based colour applications.

The formula is enriched with Argan Oil, rich in fatty acids and vitamin E, helping to preserve hair hydration and scalp comfort. An essential care when aiming for high intensity and coverage.

During application, comfort is maintained. AromaGuard technology reduces the perception of odour by up to 70%, replacing it with a soft and pleasant fragrance.

Colour precision. Maximum coverage. An intense medium brown designed for professionals who demand reliable results… every day.
