Hair Dryer

Also known as a blowdryer. A blowdryer is electromechanical device designed to blow cool or hot air over wet or damp hair, in order to accelerate the evaporation of water particles and dry the hair. The usage of blowdryers also allows to better control the shape of the hair in the process of styling, by accelerating and controlling the formation of temporary hydrogen bonds inside the hair. These hydrogen bonds are very powerful (allowing for stronger hair shaping than even the sulfur bonds formed by permanent waving products), but are temporary and extremely vulnerable to humidity, so that they entirely disappear with a single washing of the hair.
