This is a single-use ceramide treatment from the Korean brand Farmstay. I used two of these. This is an 8-piece set, and individual sales are not possible (。-人-。) How to use: After shampooing, dissolve a small amount in a separate container with water to create a creamy treatment. Apply to the ends of your hair, and then rinse. You can also apply it directly as a liquid. Ships the same day.
