The 18-year-old singer-and-actress - who is the daughter of Will Smith and Jada Pinkett- Smith - rose to fame at the age of 10 with her song 'Whip My Hair' and later made the drastic choice to lose her locks during her tour of the same name.
The 'I Am Legend' star confessed she made the change because she was "just over it" and thought the track was a symbol for "doing whatever you want" and had nothing to do with hair anyway.
In an interview with InStyle, she said: "I was just over it; the truth of the song is 'Do want you want;' it doesn't actually have to do with hair. 'Whip your hair' is just a symbol for doing whatever you want.
"So in a way, I feel like it wasn't even a rebellion because the song was saying that, and I was doing whatever I wanted and just being wild -- but obviously, it was a rebellion to people who thought it meant something different.
"I was just over it; I was literally so done and said, 'I'm going to show people that I'm not attached to this.' "
Willow has now grown her hair back and admitted that she feels her look is a "rebellion" in itself as "just being a young black woman with natural hair" does not adhere to conventional beauty standards.
She explained: "I look different than most girls who are featured in editorial magazines and fashion and all of that. So I feel all of that, just being a young black woman with natural hair. Those things are a rebellion in themselves."
