To support his family, he sold Christmas cards and newspapers to help support his family. He was eventually sent to live in a foster home and even spent some time in a gang before joining the military. In 1980, he formed John Paul Mitchell Systems with hairdresser Paul Mitchell with a $700 loan and sold the shampoo door-to-door while living in his car. DeJoria also owns 70 per cent of The Patron Spirits Company. The company is an ultra-premium tequila brand, and in 2011 they sold approximately 2,450,000 cases.
