Constant styling, coloring, and heat can damage hair. Wigs provide a way for actresses to change looks without compromising hair health. Wigs allow for quick transformations between scenes or episodes, which is especially helpful in shows with multiple time jumps or alternate realities. In long-running series, maintaining the same hairstyle can be difficult. Wigs ensure consistency across scenes and shooting schedules.
Lucy Liu in Ally McBeal often used wigs for different looks in various episodes. Sarah Jessica Parker in Sex and the City used wigs to switch between stylish, elaborate hairstyles. Claire Danes in Homeland sometimes wore wigs to portray her character during undercover operations. Many actresses, including Emilia Clarke (Daenerys Targaryen) and Sophie Turner (Sansa Stark), wore wigs for historical/fantasy authenticity.
