Dry shampoo is used to make hair look clean and fresh, and it is beneficial for people who go to work or perform other activities where they want their hair to look great but do not have time to wash it.

But how does dry shampoo work? It is made from powder and is sprayed onto hair, appearing shinier. This article will learn how it works and examine its pros and cons.

How Does Dry Shampoo Work?

Hair follicles cover your scalp. These follicles do more than produce hairs. They also produce sebum, natural oil that softens the hair and gives it its texture.

Sebum serves an essential function. Sebum softens hair and protects the skin beneath it. Oils and sweat can build up on your hair when you work up a sweat or spend time outdoors.
