Often, when women dye their hair, the result obtained is very different from what they expected - it can turn out darker or lighter, with cooler or warmer tones, or it may show unwanted yellowing and brassiness that deviates drastically from the intended color. To correct this issue, specialists from the German brand Wella Professionals recommend the use of ReNew Activator Liquid. This product is simple and convenient to use at home. The liquid reduces the intensity of the artificial tone, decreasing the depth and saturation of the color. Its interaction with the struttura of the hair ensures the preservation of natural melanin - your natural color does not lighten. The absence of aggressive components guarantees a gentle interaction with both the hair and the scalp. The product does not trigger allergic reactions or irritations.|| Use in combination with Color Renew Crystal Powder.
