Sometimes you don’t have time for a shower but your hair is greasy. Other times, your hair smells like smoke from riding in your friends car. How do you escape the grease or smell if you don’t have time? Dry Shampoo is your answer. It is a waterless way to freshen hair by just some simple sprays. It works by absorbing excess dirt and oil. It shouldn’t act as a replacement for normal washes but is definitely good when you are “on the go.” One of our favorites is Batiste Tropical Dry Shampoo.
