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.’”
