Wash your head with soda. Feels like going into an onsen and feeling comfortable. Helps clean the pores.  Also make more hair volume. After that, continue with shampoo&treatment.  I feel soft and smooth when I touch my hair. The scalp and hair are not oily.  Feeling scent of aroma shampoo Hair Style stayed for a week.  Without having to style it yourself. Shampooing by myself or Shampoo Blow dry at a hair salon probably won’t do this.  Never tried anything like this before.
