The one natural ingredient that keeps your bleached hair healthy, according to Zoe Kravitz

With every drastic beauty transformation, adjustments must be made so you can care for your new look, whether it’s totally different hairstyle, a (healthy) gel manicure, or anything else in between.

That’s especially the case for bleached hair, as Zoe Kravitz knows. The rockstar spawn and actress on HBO’s Big Little Lies recently dyed her black mane a white-hot blonde, which seems to be trending nowadays (just look at Allison Williams and Cara Delevigne).

Though the new ‘do certainly isn’t done in a natural way—it’s called bleached for a reason—Kravitz has proven that you can still care for dramatically lightened look while staying on the non-toxic side of things.

What’s the actress/musician/general badass using to keep her locks on lock? Coconut oil (of course), according to Vogue.

“My hair breaks really easily, and I think I leave a trail of blonde hair everywhere I go right now,” Kravitz says. But she has found that the MVP of natural beauty has helped her care for her tresses, which have certainly gone through a lot in terms of her dye job.

It’s something other stars have been hip to, as well—Eva Mendes, Nicole Richie, and Priyanka Chopra all use the tropical oil for lust-worthy, healthy hair. Hey, sometimes the best answer is the simplest one.

Coconut oil’s not the only natural wonder out there—you’re probably using jojoba without knowing it. And  have you tried tea tree? It’s another multitasker—here are 5 brilliant ways to use it.
