Achieve powerful, long-lasting color with Kera Color® No.4 Brown, a permanent ammonia hair color designed for high-performance results. By effectively opening the hair cuticle, it enables deep pigment penetration for intense, durable color and excellent grey coverage. This formula delivers a natural, balanced brown shade that lasts, while its smooth texture ensures even, controlled application for a professional-quality finish.

Beyond performance, Kera Color® delivers advanced care. Enriched with a double conditioning system featuring wheat protein and quaternised honey, it helps strengthen the hair fiber while maintaining softness and shine. The post coloration conditioner is formulated with color retention and UV protection, helping preserve the intensity of the shade while shielding hair from external damage. Hair feels stronger, smoother, and looks vibrant long after coloring.
