After shampooing, towel-dry thoroughly. Protect the hairline and surrounding skin with a protective cream. Wear gloves and apply an appropriate amount to the hair with a comb or similar tool, avoiding contact with the scalp. Cover the hair with a cap and allow the color to process at room temperature, applying heat if needed. Check the color, rinse thoroughly with water, shampoo twice, and finish with a hair treatment. Dry thoroughly.
Avoid contact with skin and clothing, as stains can be difficult to remove. Do not use on an irritated or damaged scalp. If the product gets into your eyes, rinse immediately. Stop use if irritation or other unusual reactions occur during or after use, and consult a dermatologist. Close the cap tightly after use. Keep out of reach of infants and young children. Do not store in extremely hot or cold places or in direct sunlight. Keep away from flames.
