DALLAS , Texas - Guy Mascolo, co-founder of the international hair salon Toni & Guy, died Wednesday. He was 65.

Mascolo suffered a fatal heart attack and died at his Dallas home, his family said.

Guy Mascolo founded the renowned hairdressing company with his brother, Toni Mascolo, in London in 1963 when they were both teens.

With skills learned from their hairdresser father, they created a global company known for its cutting-edge salons, commitment to training stylists and popular hair care products such as Bed Head, S-factor and Catwalk.

Guy Mascolo was chairman of Dallas-based Toni & Guy USA, which has 56 salons and 11 cosmetology schools.

Born Gaetano Mascolo in Southern Italy, Guy Mascolo was the second oldest of Francesco and Maria Mascolo's five sons. The Mascolos immigrated to the United Kingdom in the mid-1950s.

In 1983, Guy Mascolo and younger brother, Bruno, sought to expand the business in the United States. They moved to Dallas where they opened salons in shopping malls and began growing TIGI, their professional product line. Guy, Bruno and another brother sold TIGI for $415 million in April, Bruno Mascolo said.

Guy Mascolo also was an artist who sold his paintings to raise money for charities.
