ARE HENNA TATTO SAFE?

FDA has received reports of adverse reactions to some “henna”  and “black henna” temporary tattoos. Here is information about the safety of these products and how they are regulated.

Henna, a coloring made from a plant, is approved only for use as a hair dye. It is not approved for direct application to the skin, as in the body-decorating process known as mehndi. This unapproved use of a color additive makes these products adulterated. It is unlawful, for example, to introduce an adulterated cosmetic into interstate commerce. 

Because henna typically produces a brown, orange-brown, or reddish-brown tint, other ingredients must be added to produce other colors, such as those marketed as "black henna" and "blue henna." Even brown shades of products marketed as henna may contain other ingredients intended to make them darker or make the stain last longer on the skin.

The extra ingredient used to blacken henna is often a coal-tar hair dye containing p-phenylenediamine (PPD), an ingredient that can cause dangerous skin reactions in some people. That's the reason hair dyes have a caution statement and instructions to do a "patch test" on a small area of the skin before using them. Sometimes, the artist may use a PPD-containing hair dye alone. Either way, there's no telling who will be affected. By law, PPD is not permitted in cosmetics intended to be applied to the skin.

If you have a reaction to or concern about a temporary tattoo or any other cosmetic, in addition to recommending that you contact your health care professional, FDA asks you to contact MedWatch, the agency's problem-reporting program. You can also call 1-800-FDA-1088 to report by telephone, or contact the nearest FDA consumer complaint coordinator in your area.
