'Divergent' Lead Shailene Woodley Reveals Her (Unusual) Beauty Secrets

Shailene Woodley, the natural beauty appearing in the upcoming "Divergent," has spilled the secrets of her youthful glow to Into The Gloss.

And some are admittedly a little odd.

The 22-year-old "Descendants" actress raves that eating clay is a great way to stay lovely.

"Clay is one of the best things you can put in your body," she says. "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 with negative isotopes. And, this is crazy; it also helps clean heavy metals out of your body."

Woodley has also embraced trendy oil-pulling, an ancient manuever for oral and overall health.

"It's amazing! It really makes your teeth whiter, because the plaque on your teeth is not water soluable, it's fat-soluable."

How about that shiny hair?

"I basically have horse hair," Woodley jokes. "It's so low-maintenance. The less I put in it, the better... I only shampoo it like once a month."

But wait, there's more.

"Another thing I like to do is give my vagina a little vitamin D. I was reading an article written by a herbalist I studied about yeast infections and other genital issues. She said there's nothing better than vitamin D. If you're feeling depleted, 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."

So, who's ready to jump on board with these tips? I'll grab my beach towel and meet you on the deck.
