"She's a queen!" is the vibe you get when an African American woman wears her hair wrapped. Head wraps aren't reserved for the orthodox Rastafarian, or the women with an Afro-centric style. Protecting hair from the, wind, rain & snow, and retaining moisture is just some benefits of keeping your hair wrapped.

The African American headwrap holds a distinctive position in the history of American dress both for its longevity and for its potent signification's. It endured the travail of slavery and never passed out of fashion. The headwrap represents far more than a piece of fabric wound around the head.
This distinct cloth head covering has been called variously "head rag," "head-
tie," "head handkerchief," "turban," or "headwrap." I use the latter term here. The headwrap usually completely covers the hair, being held in place by tying the ends into knots close to the skull. As a form of apparel in the United States, the headwrap has been exclusive to women of African descent.
The headwrap originated in sub-Saharan Africa, and serves similar functions for both African and African American women. In style, the African American woman's headwrap exhibits the features of sub-Saharan aesthetics and worldview.
