Sophie Turner has revealed a dirty little secret from Game of Thrones.
The actress, who plays Sansa Stark in the hit HBO show, has revealed that for several seasons she wasn't allowed to wash her hair.
Stark told InStyle the rule came into place in recent seasons to portray the character's growth.
"For the first few seasons I was allowed to wash my hair because I was an aristocratic young girl," she said.
"Towards season five, they started asking me to not wash my hair and it was really disgusting ... for a couple of years I was living with pretty greasy hair."
