1. Shake the product up and down and open the cover.
2. Turn the top half counterclockwise until there is a "click" sound.
3. Turn the product upside down and press the scalp so that the nutrient solution is evenly applied to apply the nutrient solution.
(If the nutrient solution does not come out, turn it over open and shake it 10 to 20 times before using it.)
4. When it is sufficiently applied to the scalp, lock the top clockwise and scrub it.
5. Rinse thoroughly with lukewarm water.
