How to use
Use on wet hair after towel drying. (1) After towel drying, take a 500 yen coin-sized amount in your hand and work it into your entire hair (from roots to ends). We recommend applying it in layers several times. For semi-long hair, 3-4 500 yen coin-sized amounts are appropriate. (2) Dry thoroughly with a hair dryer.
