After washing your hair with clear water, dry the water with a towel, squeeze the "one-wash color" I and II dye paste into your hand at the ratio of 1: 1, and gently stir. The amount of long hair can be increased appropriately, and the amount of short hair can be reduced (the shampoo used for the first time is twice as much as usual, and the amount of trial package is only suitable for local use).
Rub it on your hair repeatedly. You must let the "one-wash color" touch the roots of every hair, especially the temples. Stick to the basic dry foam for 5- 10 minutes, and then rinse it clean.
First-time users, once a week for 3 weeks, then once every 2 weeks for 2 times, and once in the last month, the effect is the best!
