There are a variety of options on the market, so it is important to choose one that will suit your specific needs. For example, you may want a compact and portable one that can be moved from room to room and easily stored when not in use. You may also want a wall-mounted drying rack that can be used in small spaces, or a folding rack that is easy to fold up and store when not in use.
Safety Features
Most hair dryers feature a safety cut-off switch, a bimetallic strip or thermal fuse that cuts off power when it detects high temperatures. This is to prevent your scalp from being burned by hot air from the heater.
The heating element inside most hair dryers is a bare, coiled nichrome wire wrapped around insulating mica boards. This type of metal is much more resistant to rust than copper or iron, which would oxidize in the presence of the high temperatures of hair dryers.
Ceramic-coated heating elements are becoming more popular these days, as they tend to heat up quicker and evenly. They also have the added benefit of reducing drying time.
A concentration nozzle or diffuser will usually come packaged with most hair dryers, which helps to direct the flow of air into a single section of the hair and reduces frizz and curling. A diffuser is especially helpful for curly hair types, which can be difficult to dry by blowing directly into the hair.
