Matrix Socolor Pre-Bonded Permanent Pre-Mixed 90ml

When comparing the Matrix Socolor Permanent Pre-Mixed dye and the ColourB4 Hair Colour Remover, the most significant distinction lies in their intended purpose. The Matrix Socolor product is designed to deposit permanent color onto the hair, providing a lasting shade change. Conversely, the ColourB4 is specifically formulated to strip existing color through a decolorization process. Both options share the beneficial feature of being ammonia-free, which is often preferred for gentler chemical treatments. While the Matrix product aims for color creation, the ColourB4 product focuses on color correction or removal. Therefore, your choice hinges entirely on whether you wish to add permanent color or remove what is already there.
