14. Francesca Curran (Skinhead Helen)

She made a splash in the fifth season and is popular for terrorizing the inmates with her bald and tattooed look. It is a big transformation for Curran who went bald for the role and she had to re shave it every morning so that the tattoos could be applied on her face and neck. The eyebrows are painted white, teeth are missing, under eye make up is dark. In reality she is very feminine and flaunts differently styled wigs.
