Why Use a Cool Air Hair Dryer?

Hair drying is a part of many morning routines. Using a cool air hair dryer will minimize the damaging effects of heat on your hair while still allowing you freedom of style.

Heat Damage

Cool air dryers are an alternative to hot air hair dryers. Continuous exposure to heat can cause damage since heat removes both surface moisture and your hair's natural moisture, causing harm to multiple layers of the hair cuticle.

Hair Types

Celebrity stylist David Evangelista advocates cool air drying as particularly important if you have hair that is already brittle or curly. These types of hair are more susceptible to heat damage.

Setting Styles

Use the cool air to set hair that is already warm from another hair styling tool or from hot air. Cooling the hair quickly will maintain the style.

Power

Cool shots on hair dryers are just as powerful as the hot air settings, according to research done by Stan Eisenstein and Jeff Simpson for a physics journal.

Other Technology

Ionic and tourmaline hair dryers add negative ions, locking in the moisture. These can be used on both hot and cool air hair dryers.
