Cheating in Henna products can be done by adding chemicals and other synthetic compounds in order to strengthen the dye and accelerate the speed of the stain absorption by the skin. The most common way to cheat Henna powder goes by adding PPD (Para-phenylenediamine). PPD is a chemical substance used in hair dyes, textiles, and other industrial products. It has the chemical formula C6H4(NH2)2. PPD is an aromatic amine that is recognized a strong allergen and can cause skin sensitization, itching, redness, and in severe cases, blistering and permanent scarring. For these reasons, it is recommended to avoid using hair dyes or products that contain PPD, especially for people with a history of skin allergies or sensitivities.
Also, some black Henna products contain Lead Acetate!
Lead acetate is a chemical compound with the formula Pb(C2H302)2. It is a white crystalline substance that is soluble in water and has a sweet taste. Lead acetate is sometimes used as a sweetener in food and tobacco products, but its use is largely discontinued due to concerns about lead toxicity. Lead is a toxic metal that can cause health problems such as anemia, abdominal pain, joint and muscle pain, memory loss, and decreased IQ of children. In addition, lead exposure can increase the risk of high blood pressure, heart disease, and reproductive problems.
Lead acetate is sometimes added to Henna products for the same reason PPD is added, which is to increase the darkness and speed of the stain absorption by the skin. However, as mentioned above it is a toxic substance that can cause serious health problems if absorbed into the body. These two chemicals are the most famous when it comes to cheating in Henna, and their side effects were the main and direct reason for black Henna products to be prohibited by the authorities of several countries.
