Shailene Woodley in The Secret Life of the American Teenager
For those who have read the book or want to know about the film, we've gotten our first tidbit of production news. Shailene Woodley, who will be playing the lead character of Hazel, has decided to chop of all her hair. As we know, Hazel has cancer and has gone through chemo, and she doesn't have a whole lot of hair. While Hollywood movie magic could have actually been used to make Shailene look like she didn't have her normal long hair, she seems to want to stay as authentic as possible to honor the character and the film.
Considering the massive amounts of fans for the novel [written by John Green] and how powerful of an impact it's made, I'd say it's a good choice. John Green wrote a blog post about Shailene's decision to donate all her hair to an organization called 'Children With Hair Loss', encouraging others to do the same. He wrote, "When Shailene told me about this, I immediately thought there might be people in nerdfighteria who want to join her. (We already have one convert joining in: Shailene’s mom!) So if you have eight or more inches of spare hair, consider donating it to Children with Hair Loss. And if you do, let me know via the tags #hairforhazel or #itsjusthair, so I can put together some pictures/reblog your beautiful faces. I want to be clear that this was entirely Shai’s idea. (I don’t even think the studio knows about it.) I hope if you’re able, you’ll consider joining Shai in donating. Thanks!"

The Fault In Our Stars also stars Ansel Elgort opposite Shailene Woodley, and is actually based on the book of the same name. For those who haven't read the book or know the synopsis, it's a beautiful love story set between two cancer patients, but it has none of the cliches that may have been present in other cancer-related stories.
