Ashley Benson
Famous mostly for her part in Pretty Little Liars, she was always thought of as the blonde member of the group, but during one of the show’s seasons she surprisingly decided to dye her hair brown.
She said that she didn’t want to be blonde anymore since it’s tiring, but the character she played in the series was blonde, so she decided to wear a wig for the entire season of the show. A lot of fans didn’t know this because it was difficult noticing it’s a wig and not her natural hair.
