A hair dryer is one of the most essential beauty tools in any home. Whether you’re trying to maintain your natural texture, boost volume or create a dramatic up-do, a good hair dryer can make all the difference. But not all hair dryers are created equal and some offer more benefits than others.
In fact, even if your hair is healthy and thick, it may still take some time to dry completely without the use of a blow dryer. When you use a hair dryer, hot air speeds up the evaporation of water from your hair’s surface. It’s the same principle that makes it easier for drops of water to evaporate from a lake or ocean.
To keep you safe, manufacturers include several safety features in hair dryers. The first is a polarized electrical plug that’s designed to prevent accidental shocks when the appliance is plugged into an outlet or wall. In addition, the heating element is typically made from a bare, coiled nichrome wire wrapped around insulating mica boards. Nichrome is a good choice because it’s a poor conductor of electricity and doesn’t oxidize at the high temperatures that are used in hair dryers.
Most hair dryers also have a front grill that covers the end of the barrel. This is a great way to deter children (or anyone with inquisitive minds) from sticking their fingers or other objects down the barrel of the hair dryer where they could be burned by the heat. a hair dryer
