[4] Armenian American inventor Gabriel Kazanjian was the first to patent a hair dryer in the United States, in 1911.

This was due to innovations by National Stamping and Electricworks under the white cross brand,[6] and later U.S. Racine Universal Motor Company and the Hamilton Beach Co., which allowed the dryer to be small enough to be held by hand.

This type worked by having the dryer, usually in a small portable box, connected to a tube that went into a bonnet with holes in it that could be placed on top of a person's head.

[8] In the 1970s, the U.S. Consumer Product Safety Commission set up guidelines that hair dryers had to meet to be considered safe to manufacture.

[10] By 2000, deaths by blowdryers had dropped to fewer than four people a year, a stark difference to the hundreds of cases of electrocution accidents during the mid-20th century.

Most hair dryers consist of electric heating coils and a fan that blows the air (usually powered by a universal motor).

[citation needed] Hair dryers are available with attachments, such as diffusers, airflow concentrators, and comb nozzles.
