What is dry shampoo?
Dry shampoo is essentially a powder that you spray onto your roots to absorb excess oil, helping to refresh your hair so it doesn’t look greasy or oily. It can also add volume and texture, making your hair smell nicer. There are different forms of dry shampoo, including spray, mousse, foam and powder, but the most common type comes in a spray can, which is easy to apply and yields the best results.
