Safety: Black Henna and PPD

Now that you know what natural henna looks like, let's discuss "black henna." Products called "black henna" typically contain paraphenylenediamine (PPD), also known as coal tar or henna stone. PPD is a highly hazardous chemical and should never be applied to the skin. It's the same chemical found in hair dye, notorious for causing allergies and labeled with warnings on hair dye boxes.

In the USA, PPD is legally allowed in hair dye in quantities of 6% or less. However, in black henna, it's often found in concentrations of 20-70%. This means prolonged exposure to high levels of PPD directly on the skin, unlike hair dye which is typically applied only to hair, not touching much skin, and for a short duration of time.

PPD not only poses carcinogenic risks but also enters the bloodstream and organs, particularly affecting the liver and kidneys causing permanent damage. Each exposure increases the risk of sensitization to PPD, potentially leading to severe allergic reactions and the need for lifelong precautions, like carrying an EpiPen.

Moreover, once sensitized to PPD, individuals may also react to similar additives found in various products like food coloring, medications, sunscreen containing PABA, black clothing dye, rubber, and pen ink.

After becoming sensitized to PPD, something as simple as dying your hair can land you in the hospital like Pauley Perrette.

Prioritize safety by opting for well-sourced natural henna to avoid the dangers associated with PPD exposure.
