Olivia has alopecia(秃头症)．“Most people think I have cancer，” she says，“which is totally fine.But I'm not sick or anything.” She decided early in her childhood—months after losing most of her hair—not to cover up her condition. “When I was 8 years old，I got a custom wig(假发)，” she says.“No one knew I was bald.It looked completely natural.But one day I woke up and said，‘Mom，I'm not wearing my wig to school.I want people to know the real me.’”
