This is a new, two-layer water treatment that you shake before use. The beauty layer, which provides inner care, contains CMC components essential for hair flexibility, while the oil layer, which provides outer care, contains oil keratin to repair damage and improve hair strength. This two-layer formula leads to shiny, smooth hair. *This is a refill pouch. Please note that the main bottle is not included. You can use a container from Muji, a 100-yen shop, or similar. For those who want to try it but don't need a lot, or for those who find the initial purchase restrictions troublesome, please feel free to try it. Please check the official website for usage instructions. Thank you for viewing.
