Blow Dryer

Most everyone, particularly women, are familiar with the concept of a blow dryer and how it works. You shower and wash your hair, needing to dry it quickly for any number of reasons. So, you reach for your handy and trusted blow dryer and dry and style your hair, which can typically be done in any number of ways due to the attachable gadgets that now come with most dryers. Several decades ago, things were much different. Women would wash their hair and then have to wait for it to air dry. This could take hours depending on the length and thickness of the hair. Today’s gadgets however, have given women a much better and faster way to achieve great style.

Blow dryers first hit the consumer market in the 1920s. The first models proved to be a bit dangerous as hundreds of women were electrocuted after they dropped the devices into bathtubs and sinks filled with water. Today’s models however are much safer to use and contain warnings against submerging them in water. All portable hair dryers (blow dryers) are required by the United States government to protect against electrocution by containing a GFCI or Ground Fault Circuit Interrupter. If you do drop the dryer in water while plugged in, this circuit will trigger and trip or turn off the electrical current running to the device. Of course, dropping it in water can damage the blow dryer even if it is not plugged in at the time.

Blow dryers, because of their intense heat, also need other safety factors in order to keep them from burning the skin or your hair. Manufacturers of these devices have the burden of determining different ways that their dryers may be misused by the public and providing safety measurements for these uses. The barrel for instance, must be designed so that it does not become too hot when in use. The barrel, or the end of the blow dryer where the air comes out, contains a heat shield that prevents it from burning users when touched. It is important to understand that you can burn your scalp if the temperature of your blow dryer gets too hot. In fact, temperatures higher than 140 degrees Fahrenheit can burn the scalp. For safety measures, hair dryers have heat sensors that trip the circuits if the air coming out of the barrel ever gets close to 140 degrees Fahrenheit.

You have likely noticed the protective screen that covers the fan on your blow dryer. All dryers have them and they are designed to keep lint and other particles from building up on the fan or entering the dryer’s motor. It is important to routinely check this screen on your blow dryer and remove any lint or other materials that may build up. If there is too much lint building up on the screen, the airflow to the dryer will be blocked and the dryer will overheat. Newer models from certain manufacturers actually contain removable lint screens much like those on traditional clothes dryers. These are much easier to clean.

In addition to the screen covering the fan, there is typically a screen covering the end of the barrel. This screen is made from materials that are heat resistant and makes it much more difficult for small children to get their fingers or hands stuck in the barrel. In addition, it protects anyone who may be so included from sticking things in the barrel which could cause burns from the heating element.

Blow dryers have been around for the better part of the century and during that time, they have changed dramatically. Today’s portable hair dryers come in a wide variety of styles, sizes and shapes and give women and men alike the ability to dry and style their hair with ease and convenience.
