WHAT IS BLACK HENNA?
The "black henna" or "neutral henna" tattoos, these patterns painted onto your skin are readily available everywhere. They may also be available at festivals and fairs, and to buy online.
It is mix of various chemicals, specifically, PPD (Paraphenylenediamine). PPD is a chemical substance that is widely used as a permanent hair dye.
​
The hair dye is permitted in many countries but when use is strictly controlled and by professional. When it is applied in hair, colourist wear gloves and it does not touch the scalp.
People who manufacture and sell the black henna are mostly undocumented. There is no control on how much PPD is being added. It may show immediate allergic reaction or may show up after weeks or months or even years in some cases. You may be happy to get black colored design in the short term but ultimate results may be devastating.
CHEMICAL BURNS FROM PPD (Paraphenylenediamine)
Not everyone has a reaction to black henna, but it can be painful if you do.
"The signs range from discomfort, such as burning or tingling, too painful stinging, swelling, redness and blistering of the skin," says Dr Flower.
"This can become very severe and lead to permanent scarring of the skin in the outline of the tattoo."
If you get a reaction like this, contact a doctor immediately and tell them what has happened."You will probably be treated for chemical burns and possibly allergic reactions."
If the reaction persists or gets worse, go back to the doctor, as the painted area can also become infected.
