17-year-old Andrea Salazar doesn't let cancer stop her from being a princess. 

Salazar lost her hair to chemotherapy, and felt her self esteem suffering. A model, she hesitated to be photographed without her hair, but together with photographer Gerardo Garmendia, decided to do a photoshoot with the theme: "a princess without a wig."

She says, "I’ve learned that the hair on someone’s head doesn’t define who they are as a person, but their actions and the way they treat others do."
