Shailene Woodley, the star of "Divergent" and "The Fault In Our Stars," has made a name for herself in Hollywood, but it's not just her leading roles that have garnered her so much attention.

The 22-year-old actress — who eats clay, bottles her own spring water and recently gave away her house — has developed a reputation as a sort of a new-age hippie.

Like many young stars, Woodley is often asked for beauty tips, but instead of gushing about expensive cosmetics or detailing an extensive skincare routine, she dolls out beauty advice of a different type.

Some of her tips may sound a bit wacky, but in today's beauty-obsessed culture there's no doubt they're refreshing. Here's a roundup of some Woodley's most memorable health and beauty recommendations.

Skincare

The secret to great skin? Woodley says to laugh often and go easy on the soap.

"All of my friends in their mid-thirties and early forties laugh a lot and have no wrinkles. That is the secret to good skin. I swear. Everybody has this big thing about chemicals and facials but it is just laughter."

"Use soap sparingly. Try a dry brush instead and in moments you're feeling really dirty, use natural, simple ingredient soap. Nothing artificial."

Makeup

Woodley is very vocal about this topic. While she lets herself be made up for roles and interviews, she typically avoids wearing makeup when she's not on set.

"I realized that, growing up and looking at magazines, I was comparing myself to images like that — and most of it isn't real. I don't really wear makeup that much anyway, so part of it is just a selfish, lazy thing. I want to be me."

She also makes some of her own cosmetics. Check out a few of her recipes below.

To make lipstick: "Beets are my go-to for lip color," she told InStyle. "Roast one for 30 to 50 minutes at 350 degrees, depending on the size of the beet. When cool, rub it on your lips. I eat them after.”

To make eye makeup: "To add color on the eyes, try a greens powder such as spirulina [algae]. I source mine from Longevity Warehouse. When wet, it works as a liner."

Dental care

Oil pulling, a traditional Indian practice of swishing oil in the mouth, is a staple of Woodley's beauty routine.

"It's amazing! It really makes your teeth whiter, because the plaque on your teeth is not water soluble — it's fat-soluble. So the lipids have to dissolve in fats, which is why oil works in your mouth."
And when it comes to toothpaste, she prefers to make her own.

She mixes bentonite or zeolite with coconut water and 1 to 2 drops of essential oils such as peppermint or cinnamon. When she's finished brushing, she swallows the toothpaste "to get a dose of minerals."

Hair care

Woodley says she shampoos her hair only once a month — "the oilier, the better"— and claims not to even own a hairbrush.

However, she does have a DIY conditioning treatment she uses: coconut oil or olive oil.

"I'll put one tablespoon on my thick hair for a few minutes before bed and rinse out. It will leave your hair oily if you use too much, so start with small quantities to find out how much works best for your hair type."

Eat some clay

Woodley first heard about ingesting clay from a taxi driver, and she had to try it for herself.

"I’ve discovered that clay is great for you because your body doesn’t absorb it, and it apparently provides a negative charge, so it bonds to negative isotopes. And this is crazy: It also helps clean heavy metals out of your body."

The practice of eating clay is known as geophagy and occurs in numerous cultures across worldwide.

"You should obviously be careful about your source," Woodley said. "Bentonite clay is good, but Mountain Rose Herbs has a great clay source."

The importance of vitamin D

Getting a little sun helps Woodley both "internally and externally," she says — and she means everywhere.

"... If you're feeling depleted [of vitamin D], go in the sun for an hour and see how much energy you get. Or, if you live in a place that has heavy winters, when the sun finally comes out, spread your legs and get some sunshine."

Woodley's top beauty tips

"Get in a bath and look at your body and be like, 'Wow, thank you so much for hosting my mind and my heart,' like as women you know, and also be pregnant with the world," she told People. "I think that's really beautiful beauty advice."

"Don't compare. Leave it all behind. Compare leads to despair. Love yourself. All of your ticks, quirks and bizarre smirks. Love it all. Embrace it. The moment we allow our minds to forget about ourselves physically, self-love can rule. And with self-love comes a glow that no product on Earth can create!"
