Consider the diffuser

When shopping for a hair diffuser, you should consider its airflow, prong length, and diffuser size. "The size or diameter of the diffuser determines how much surface area of the head will be covered," hairstylist Leigh Hardges has told Cosmo. "The cup size of the diffuser is an indicator of how much hair it can hold while drying." To sum it up: If your hair is long, you need a diffuser that has a bowl that is bigger, wider, and deeper.

"The airflow is determined by the placement and number of holes on the diffuser, which determines how quickly your hair dries," Hardges told Cosmo. If you have thick hair that takes a while to dry, a diffuser with lots of holes should be your go-to. Thinner, quicker drying hair? Fewer holes will be just fine.

Make sure it has ionic technology

Quick little chemistry lesson for you: There are little ions, which can be both negative and positive—i.e., invisible particles—floating all around us. Positive ions don't love our hair and can cause static, flyaways, and frizz. A hair dryer with ionic technology emits negative ions to cancel out the positive ions. The result? Hair dries quicker because these negative ions break up water molecules, and they even smooth your hair cuticle so you have less frizz and flyaways. In short, if you have curly hair, get a hair dryer with ionic technology.
