You may have noticed that cool button on your dryer. You know, the one your hand slides over when choosing a heat setting to blow dry. It's there for a reason, so let's tackle a few of them:

• Ice-cold relief. If you think things are heating up too much – i.e., your scalp feels like it's on fire – a blast of cold can relieve that burning feeling on your head and cool down the motor of the dryer in the process. (P.S., Beauty shouldn't be that painful, so consider a lower heat setting. Less heat, less breakage.)
• Is it done yet?! Because hair gets so hot under the dryer, it may feel warm to the touch, but not actually be totally dry. Next time, blast your head with a shot of cold to see if any hair feels damp and refocus your heating efforts in that spot.
• Lock and load. Similar to rinsing with cold water, the cool setting causes hair cuticles to close and seals in moisture. It's a great step to add in after heating and before rinsing out a leave-in conditioner. Plus, this helps set and lock a long-lasting style once you've finished.

Now go forth and shoot the breeze!
