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 wash your hair with the lather. It is important to lather generously to prevent friction, which can cause damage to your hair. To achieve a lifting effect, massage your scalp in zigzag motions as you shampoo. Use circular and zigzag movements with your fingers. *Adjust the amount depending on the level of dirt and the length and volume of your hair. Residual shampoo can cause dandruff and itching, so rinse thoroughly, approximately 2 to 3 times the time you spent shampooing. [Treatment] Step 1: After shampooing, thoroughly remove excess water from your hair. Step 2: Apply to your entire hair, blending it in. Massage the product thoroughly into your hair, especially from the middle to the ends, which tend to lack moisture. Step 3: Leave it on for 2-3 minutes, then rinse thoroughly to ensure no residue remains. For those concerned about hair damage, comb your hair using a head spa bath time brush and then leave it on for 3-5 minutes. This will allow the hair mask to adhere to each strand of hair, enhancing the treatment's effects. Then rinse thoroughly. [Out-of-bath treatment] Step 1: After washing, towel dry your hair. Step 2: Apply the mask to your entire hair, blending it in. Step 3: Dry your hair with a hair dryer. Finally, using cool air will tighten the cuticles and increase hair shine. Apply the mask by massaging it into your hair, starting from the ends, where damage has accumulated.
