The way you dry your hair and the tools you use matter when it comes to your overall style. So when you're looking for a new hair dryer, there are a few things to consider. First, start with your own hair. Is it damaged? If so, it'll take less time to dry and may benefit from a lower-wattage blow dryer or one with variable temperatures. Thicker hair needs a higher wattage to get the job done quickly. But for the most part, a hair dryer with 1,800 watts is suitable for most everyone. It's helpful to have multiple speed and temperature settings on the dryer so that you're able to adjust for your hair's wetness and individual texture. Medium heat will pull the wetness out of hair, and high heat sets the style, as a general rule. Hairstylists tend to agree that the materials - whether it's ceramic, tourmaline or something else - may not matter as much as the products you use.
