Alicia's head wrap tonight, November 29, Professor Quirrell!
I have defended Alicia's head wraps during the knockouts, battles and blinds because she has naturally curly hair and those pieces are filmed altogether and then mixed up so her hair has to be identical each episode so she had to wear a head wrap because of her curly hair.
Tonight was a live episode though, she could have let the curls fly. And she looked like Professor Quirrell from Harry Potter and the Sorcerer's Stone in tonight's head wrap. As evidenced here:
