Advertising art director Jackie De Jesu started out this year with a simple mission: bring the smelly, plastic, disposable showercap into the 21st century. Her stylish SHHHOWERCAPs are reusable, washable, and made out of high-performance, waterproof material–perfect for a large population of women who don’t wash their hair everyday.
