A hair clip assembly for protecting pretreated hair from damaging effects of a treatment chemical applied to new hair growth. The hair clip assembly comprises two spring-biased jaw members, each having a substantially flat, rectangular hair shield extending therefrom. After selective attachment of the hair clip assembly to a section of hair, in proximity to the junction between the pretreated hair and the new hair growth, the hair shields protect the pretreated hair from needless exposure to the treatment chemical.
