When we spotted Lupita Nyong'o in twists back in March, her hairstylist Vernon François said that the protective style was also a way to give her hair a rest. And even though she recently served us with four insanely fierce looks over at Cannes, those hairstyles still protected the health of her real curls. "I’m a big believer that if we don’t need to use heat, combs or hairspray, then I will do my best not to," says François. "If I design a hairstyle that can last a couple of days, we definitely try to embrace the look. It’s important to know that styling kinky hair every day can lead to hair loss and long-term damage."
