The study investigates the presence of heavy metals and para-phenylenediamine (PPD) in Black Henna samples marketed in Egypt. Results showed that PPD was found in all samples at concentrations exceeding safe limits, and several heavy metals were detected above permissible levels for cosmetics. The findings highlight potential health risks associated with the use of Black Henna, particularly for children, and suggest the need for further research.
