5 Weird And Wonderful Hair Hacks Celebrities Swear By

We love when our favorite stars dish about the beauty products they can't live without, but sometimes the products they swear by are a tad unconventional or just downright weird.

Case in point -- Suki Waterhouse recently told Us Weekly that she occasionally rinses her hair with Coca-Cola.

The model-turned-actress said that she doesn't like the look of her fine hair when it's first washed, "but Coca-Cola makes it tousled, like [she's] gone through the Amazon or something."

Noted. Since you're likely thirsty for more unconventional beauty hacks, we rounded up four more wacky products celebrities love to put in their hair. Check them out below.

“I've also had pink hair - when trying to dye it red - and green hair, when trying to dye it brown. That was awful actually, I used henna, thinking I was being all organic and clever, and it was totally impenetrable - I just couldn't get it back to normal. The only thing that made any difference was ketchup, so for about a year-and-a-half I had to put tomato ketchup on my hair under heat until it went back to normal.” -- Sienna Miller, Vogue UK

"On tour, we would have to put it up in a ponytail super fast, and snatch it up from being down in extensions [in between songs on stage], so the best thing we used was olive oil. It’s crazy. Because it was cheap, we would just pour it on, slick grease it back, and then stick the whole long extension and all the rubber bands in, and so a lot of times we’d get right on the tour bus, and I would just wrap it up in a bun, throw a scarf on or a shower cap when I got in my bunk, and sleep in it—wash your hair the next day, and it’s like silk." -- Fergie, Byrdie

“She gave us a book she bought at a garage sale about natural beauty remedies and we used to look up everything, like how to make masks out of oatmeal or give our hair highlights using henna tea or even rum. Once a year, we all still get together and put mayonnaise in our hair for old times sake.” -- Zoe Saldana, talking about her mother, Allure

“And seeing photos of my mother from the ’60s and ’70s, she was a total rebel with her style. She had extremely fine hair and washed it with detergent to coarsen it up and had this amazing Afro.” -- Solange Knowles, New York Times
