Spray product directly at roots. Do not brush through or rub in.
Leave on overnight for maximum oil absorption.
In the morning, massage or brush any remaining product through hair.
For optimal results and maximum odor and oil absorption, leave powders near your roots for at least 4 hours. By using the overnight dry shampoo before bed, it allows enough time for the product to absorb odor and oil so you wake up with fresh hair (and a beautiful smelling pillow).
