It was the actress's mom who instilled in her at a young age what beauty is all about. "Growing up she always encouraged my sisters and I to be as natural as possible," Saldana told Allure. "She gave us a book about natural beauty remedies and we used to look up everything, like how to make masks out of oatmeal. Once a year, we all still get together and put mayonnaise in our hair for old times' sake."
