Stop calling that henna. It's PPD and there's no henna in it. Henna is a greenish powder that won't penetrate your skin and then travel through your blood stream and cause damage like PPD does. Some people are born sensitive to PPD, while others become sensitive to it through repeated contact. www.hennapage.com/henna/ppd/
Real henna is way better for you. black henna's made from hair-dye, and the chemical levels in it are so high that it can permanently scar your skin, plus leave you with a sensitivity to hair dye that could possibly land you in the hospital.
