While at least a working knowledge of the English language is generally required to be successful at job hunting in the U.S., having a bilingual cosmetology education might actually make you a more attractive potential employee for some salons, especially ones that have a largely Spanish-speaking customer base. In 10 years, some experts predict that over 50 percent of the country will be speaking Spanish. Being able to translate between the English and Spanish languages is beneficial in a salon that takes on clients who speak either Spanish or English. Areas like Los Angeles , New York , Miami and Houston will be experiencing a high demand for professionals who can speak Spanish.
