Kyogoku W Treatment I looked for the same product on Mercari, and this is currently the lowest price!! The industry's first W-function treatment that can be used whether you rinse it off or not. You can easily recreate the formula chosen by professionals at home. Damages are repaired from within the hair with plant-derived oils & amino acid-based repair ingredients. Automatically adjusts the balance of moisture and oil, keeping the hair optimally moisturized and shiny. Coating function protects hair from dryer heat and UV rays. It doesn't feel sticky, yet it has a manageable texture, leading to beautiful hair with every use. Can be used flexibly to suit your lifestyle, such as in the busy mornings or after taking a bath.
