Parisian hairdressers continued to develop influential styles during the early 19th century. Wealthy French women would have their favorite hairdressers style their hair from within their own homes, a trend seen in wealthy international communities. Hairdressing was primarily a service affordable only to those wealthy enough to hire professionals or to pay for servants to care for their hair. In the United States, Marie Laveau was one of the most famous hairdressers of the period. Laveau, located in New Orleans, began working as a hairdresser in the early 1820s, maintaining the hair of wealthy women of the city. She was a voodoo practitioner, called the "Voodoo Queen of New Orleans," and she used her connections to wealthy women to support her religious practice. She provided "help" to women who needed it for money, gifts and other favors.
French hairdresser Marcel Grateau developed the "Marcel wave" in the late part of the century. His wave required the use of a special hot hair ironand needed to be done by an experienced hairdresser. Fashionable women asked to have their hair "marceled." During this period, hairdressers began opening salons in cities and towns, led by Martha Matilda Harper, who developed one of the first retail chains of hair salons, the Harper Method.
