Kamaleão Color Colored Toning Mask 150ml (Hair Dye) Images are for illustrative purposes only! Results may vary depending on the base color and application method. We recommend always performing a strand test before applying the product to the entire head of hair. Pigmenting masks can, in some cases, cover up to 80% of gray hairs. Remember that this is not the rule, it's an exception. Therefore, it's always important to perform a strand test beforehand to ensure you achieve the desired result. In most cases where the Pigmenting Mask is applied to gray hair, it does not pigment. And if it does take to the hair, it may wash out in the first few washes.
