This Prom Queen's Henna Tattoo Turned Into A Total Nightmare

    Beware of black henna.

    This is Mary Bates, a 16-year-old from St Albans, Hertfordshire, U.K.

    On a recent vacation to Turkey, Mary got a black henna tattoo of a dreamcatcher on her left ankle.

    You can see it here.

    But a few days after she got the tattoo, it began to scab up and burn.

    Where traditional henna is made from a flowering plant common in Asia and Africa, black henna is synthetic.

    According to the FDA, black henna is sometimes traditional henna mixed with other ingredients, or it may simply just be coal tar hair dye.

    For Mary, the black henna tattoo resulted in a horrible burn.

    The aspiring model and makeup artist says she's hoping one day to be good enough at theatrical makeup to be able to cover up her scar.
