PPD Black Henna, P-phenylenediamine Black Hair Dye added to Henna In recent years, PPD black hair dye has been added to henna or used instead of henna to create jet-black stains. This is dangerous and unnecessary. Though people of color may feel that a jet-black stain is the only thing that will show on their skin, natural henna colors are beautiful on dark skin, and are safe. P- phenylenediamine can cause skin blistering and lesions, often leading to permanent scarring and sensitization to many products.
