Matrix Color Sync Acidic Toners Brunette Matte is a professional hair coloring product designed to refine and tone brunette shades with a matte finish. This toner works within the slightly acidic pH range to gently deposit color, minimizing cuticle damage while depositing rich tones. It is formulated to blend seamlessly with natural or color-treated hair, offering brilliant results without ammonia, making it an excellent choice for enhancing depth and neutralizing unwanted undertones. Ideal for post-color refinement or refreshing existing color, this product allows stylists to achieve precise, consistent brunette shades with a sophisticated, non-reflective matte effect.
