Suggested amount of Agent 1: 40–50g for short hair, 50–60g for medium-length hair, and 70g or more for long hair. Generally, mix Agent 1 and Agent 2 in a 1:1 ratio. Leave to process for 30 minutes without added heat.
Choose 6% Agent 2 for hard-to-color hair, such as coarse or oily hair, through to normal hair. Choose 3.7% Agent 2 for hair that colors easily, such as fine or dry hair. If new growth is 3cm or longer, application in two stages is recommended, using different application times for new growth and previously colored lengths, or different combinations of Agent 1 and Agent 2.
Always wear gloves during application. Avoid contact with the scalp, skin, and clothing. If the product gets on the scalp or skin, immediately wipe it off with water or remover and rinse thoroughly. Stop use if the scalp is irritated or any unusual reaction occurs, and consult a dermatologist.
Keep the product and rinse water out of the eyes. If contact occurs, do not rub; immediately rinse thoroughly with water or lukewarm water and seek care from an eye specialist. Do not use on eyebrows, eyelashes, or areas other than scalp hair.
Keep out of reach of infants and young children. Do not store in very hot or cold places or in direct sunlight. Color may transfer to clothing, hats, or pillowcases when hair is wet from sweat, rain, or washing, or after using hair tonics or styling products.
