beautician (n.)

first recorded 1924, American English (Mencken found it in the Cleveland, Ohio, telephone directory), from beauty + ending as in technician. Beauty salon is from 1912, a substitution for prosaic beauty shop (1898). Beauty parlor is from 1894.

The sudden death of a young woman a little over a week ago in a down-town "beauty parlor" has served to direct public attention to those institutions and their methods. In this case, it seems, the operator painted on or injected into the patron's facial blemish a 4-per-cent cocaine solution and then applied an electrode, the sponge of which was saturated with carbolized water. [The Western Druggist, October 1894]
Back in 1917, according to Frances Fisher Dubuc, only two persons in the beauty culture business had paid an income tax; by 1927 there were 18,000 firms and individuals in this field listed as income-tax payers. The "beautician" had arrived. [Frederick Lewis Allen, "Only Yesterday," 1931]
