She has had gorgeous long locks since the beginning of her time on "The Secret Life of the American Teenager," but Shailene Woodley will soon be switching up her 'do!

This weekend, the 21-year-old actress will be chopping off her hair for her upcoming role in the new film, "The Fault in Our Stars."

However, unlike many stars, whose hair gets swept up like all the rest, Shailene will be donating hers to an organization called, Children With Hair Loss.

The Michigan-based nonprofit takes cuts of hair that are eight inches or longer and makes them into wigs for children who have lost their hair.
