I started coloring my hair when I was 14 and have tried everything. I've gone light to dark to light again. I've dyed it gray for Coachella; I've chalked it pink for a music-video shoot—and if I had it my way, it'd be baby pink every day.
It's all taken a toll on my hair. Right before I began modeling, at 17, it was the longest it had ever been without extensions. It basically hit my waist! But I wanted a more fashion-forward cut to start my career, so I chopped it off to my shoulders.
The aesthetic I'm going for now? Healthy. But it's hard to keep it that way because I put my hair through so much for my work with the extensions, styling, hot tools, and blowouts. It gets so thinned out. I can tell it's time for a salon visit when I brush through it and there are damaged little blonde wisps that break off on the brush. I get the L'Oréal Professionnel Pro Fiber Re-Create ($40; lpsalons.com) treatment. Then I use the Re-Charge at home for a boost. Other than that, I use a lot of coconut oil to keep it hydrated—and, to be honest, I use that from head to toe.
My mom has really thick Brazilian hair. But nope, I got mine from my dad. We jokingly call it "chicken feathers."
My mom has really thick Brazilian hair. But nope, I got mine from my dad. We jokingly call it "chicken feathers." Still, my mom has influ- enced how I treat my hair: She likes to use only natural or not-too-processed products. For the L'Oréal Professionnel campaign, designer Vanessa Bruno created these soft, beautiful tones for the INOA It Looks collaboration. It's ammonia-free and has an oil-delivery system, so even though we dyed my hair three different times for the shoot, it was so gentle, and my hair didn't feel damaged after.
"If I could switch hair with one of my friends, it'd be Kendall. It's really thick and beautiful. All of those Kardashian and Jenner girls have really full hair.'
Being in the spotlight, I think it's important to look put together and maintain a nice persona. My look is something that I definitely think about. Sure, there are times when I'm out in sweats, but I never want to look sloppy. My inspiration comes from models like Claudia Schiffer and Christy Turlington Burns; they always look amazing. I want to be like that in my career. I've had a lot of "pinch me, is this really happening?" moments, like shooting with Karl Lagerfeld or, last year, when a campaign I was in was all over the billboards. But there's still so much more I want to accomplish.
