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