Suggested amount of Agent 1: 40–50g for short hair, 50–60g for medium-length hair, and 70g or more for long hair.
As a general rule, mix Agent 1 and Agent 2 at a 1:1 ratio.
Allow to process naturally for 30 minutes.
Select 6% Agent 2 for hard-to-color hair, such as coarse or oily hair, through to normal hair. Select 3.7% Agent 2 for hair that colors easily, such as soft or dry hair.
If new growth is 3cm or longer, application in two stages is recommended. Apply to new growth and previously colored areas at different times, or adjust the combination 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. Do not use if the scalp has any abnormalities; discontinue use if abnormalities occur and consult a dermatologist.
Keep the product and rinse water out of the eyes. If either enters the eyes, 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. Store away from high or low temperatures and direct sunlight. Color may transfer to clothing, hats, or pillowcases when hair is wet from perspiration, rain, or washing, or after using hair tonics or styling products.
