Hilary Duff Explained Why She Dyed Hair Green

The TV star had a reason for changing up her look.

Turns out, she had a personal reason for changing things up.

"Here's the thing: Luca is very particular about how he likes my hair. There are absolutely no buns on my head, no ponytails. I'll have a ponytail and he's like, 'Um, hair down, Mom. Hair down, please,'" she explained. "Now he likes to go through his roster of colors that he knows. He's like, 'Your hair's purple,' and I'm like, 'No, it's green.' He's like, 'Nah.' I'm like, 'Yeah.' He's like, 'It's blue.' 'No.' 'It's purple.' 'No.'"

"He's very, very funny," Duff added, smiling.
