Beyoncé Knowles used to press her hair with an iron. The pop superstar — whose luscious locks are rarely out of place — admits she and her Destiny’s Child bandmates grew into the habit of putting their hair on the ironing board and ironing it! “I remember when I started doing my hair myself — I cut bangs, and I started curling my hair and pressing it, literally, with an iron,” Knowles, who’s married to rapper Jay-Z, told Allure magazine. “The girls from Destiny’s Child, we would put our hair on the ironing board, and iron it, which is so crazy! “My mom [who used to own a hair salon] was like, ‘We have to get you out of your own hair, because you are destroying it!’”
