How to use
Step 1: Pre-wash with lukewarm water before applying shampoo. Lightly remove dirt, dust, and styling products from your hair and scalp. Thoroughly wetting your hair will prevent friction between strands. Step 2: Take an amount about the size of a 500 yen coin* and spread it in your palm. Lightly lather and spread it over your entire hair. Use the pads of your fingers to incorporate air into the lather, then gently wrap your hair in the lather to cleanse. It is important to lather generously to prevent friction, which can cause damage to your hair. With a focus on the lifting effect, shampoo while massaging your scalp in zigzag motions, lifting it. Use circular and zigzag movements with your fingers. *Adjust the amount of shampoo depending on the level of dirt and the length and volume of your hair. Residual shampoo can cause dandruff and itching, so rinse thoroughly for approximately 2 to 3 times the time you shampooed.
