Before coloring the entire hair, it is recommended to perform a color test on a hidden hair strand. Choose the lightest hair strand or an area with the most gray hairs. Wear gloves. Mixing ratio 1:3 (1 part powder + 3 parts boiling water, green or black tea, coffee, or a dairy product). Apply the color generously and as hot as possible, on clean and dry hair, using a brush or hands. Start at the ends and work upwards. Wrap the hair in film (plastic bag) and a towel to keep it warm and moist. Coloring time is 25-90 minutes depending on the desired color intensity. Rinse hair thoroughly and wash with shampoo. For best results, rinse with ZENZ Hair & Scalp Rinse no. 87 after washing and before conditioner. Store in a cool, dry, and dark place.
