THE DANGERS OF BLACK HENNA

Black henna is very popular and easy to obtain on the Internet and even in some import stores. However, did you know that this product is illegal in Canada? Black henna contains a chemical molecule called paraphenylenediamine (PPD), which is normally used in hair dyes. PPD is therefore legal in hair dye products, but not in cosmetics applied directly to the skin. The import and use of black henna is therefore prohibited in Canada.

Initial contact with black henna does not always result in an allergic reaction, which can even occur up to 14 days after application. The allergic reaction may cause redness, rash, itching and inflammation. More severe reactions can include dizziness, fainting, cramps, abdominal pain and even anaphylaxis. So it's important to take the reaction seriously and consult a health professional.

If you develop an allergy to PPD, you may also be allergic to hair dyes, certain chemicals from the rubber family, certain inks and medicines. For more detailed information, please consult the Government of Canada website.

Fortunately, Adhenna Tattoo offers natural alternatives to black henna including hennagua and the jagua which are made from a Peruvian fruit, guenipa, and produce a dark brown and dark blue tint on the skin. It is therefore important to differentiate between skin reactions associated with jagua versus black henna, as they will not be treated in the same way. For more information on jagua-related rashes, please see my publication on the subject.
