Separate your hair into two-inch sections and spray at the root of each section, says Townsend.

If you don't section off your hair, product can get concentrated in one area, warns Potempa. Too much dry shampoo will leave a light-reflecting residue (that will be especially apparent if you're going to be photographed).

You're not going to get better results the closer you hold the can to your head -- in fact, the opposite is true (Potempa says this is the most common dry shampoo mistake).

Townsend recommends holding the can 6 to 8 inches away from the root of each section.

Potempa adds that you should start at your ear, and spray the dry shampoo from underneath your hair. If you don't start at the base of your hair, you won't reap the volumizing benefits of dry shampoo, and your hair can fall flat as the day wears on.

"Dry shampoos take a minute or two to absorb," says Markham. So, let the product sit for a couple of minutes before you touch your hair.

If you're pressed for time, use heat from a blow dryer to speed up the process, says Markham. "Heat helps the oils absorb and the force of the air from the blow dryer helps to distribute the product from roots through ends," he explains.

Use your fingers to gently rub the dry shampoo into your scalp, so excess product is absorbed, says Townsend. Then run a brush through your hair to comb out any tangles and distribute the product evenly.

Markham says that curling the ends of your hair post-dry shampoo is a great style refresher.

However, applying dry shampoo before using hot styling tools can dry out your hair, so Potempa advises to proceed with caution.
