Temporary henna or "mehendi" tattoos that are applied on the skin can lead to some nasty allergic reactions, the U.S. Food and Drug Administration warned Monday.

According to the agency, though the tattoos aren't permanent, they still carry risk from certain chemicals that are used in the product. These temporary tattoo shops can be seen on tattoo kiosks at beaches, boardwalks and some specialty shops.

"...Just because a tattoo is temporary it doesn't mean that it is risk free," says Linda Katz, M.D., director of FDA's Office of Cosmetics and Colors, in a statement.

Henna has been used since the Bronze Age in parts of Asia and Africa to dye skin, hair and leather. The decoration is still used during many cultural ceremonies.

However, the "black henna" used today in the place of traditional plant-based henna can cause an allergic reaction in some people as it contains p-phenylenediamine (PPD) - a chemical associated with allergy.

The agency fears that with spring break around the corner, many people might want to try the "risk-free" temporary tattoo. But for some people, this harmless fun can turn into a serious condition.

"What we thought would be a little harmless fun ended up becoming more like a nightmare for us. My hope is that by telling people about our experience, I can help prevent this from happening to some other unsuspecting kids and parents," said the father of a 5-year old girl who got an allergic reaction from a temporary tattoo.

People who'd want to place a complaint regarding the tattoo can visit MedWatch or call 1-800-FDA-1088.
