'Temporary' henna tattoo becomes permanent in viral scarring disaster.

Henna tattoos are usually a great way to get some temporary body art, but Twitter user James Colley found out the hard way that he didn't have to go under the needle to end up with something that might be permanent.

Colley received a €10 (a little over 11 bucks) facial tattoo inspired by Mike Tyson's famous ink while on vacation in Zante, Greece. The tattoo was made of "black henna," which is actually just black hair dye and does not resemble the natural, plant-based brown henna professionals commonly use. "Black Henna" contains synthetics including paraphenylenediamine, which was outlawed by the European Union because it can cause severe burns to skin.
