If you press too lightly, the 1st and 2nd agents will not come out evenly, so it will not be dyed. Apply evenly to the entire dry hair while combing, and spread it on the comb side. After applying, leave it on for about 15 minutes. Rinse well and finish with shampoo and conditioner. Be especially careful not to get the cream and rinse water in your eyes. Be sure to clean the nozzle before use.
