Los Angeles: Bradley Cooper's ex-girlfriend Suki Waterhouse has revealed rinsing her hair with aerated drink Coca-Cola is the secret behind her illustrious locks.
The 23-year-old British supermodel said she relies on the sweet soda to give her hair a boost, reported Us magazine.
"I rinse my hair with Coca-Cola sometimes. I don't like my hair when it's washed it's fine and limp but Coca-Cola makes it tousled, like I've gone through the Amazon or something," she said.
Waterhouse split from Cooper after two years of dating.
