To estimate the presence of para-phenylenediamine in various commercial hair colors, a straightforward, speedy, precise investigation used High-Performance Liquid Chromatography to find PPD in henna and determine its presence. In order to do the chromatography, stationary phase Phenomenox C18 100 mm x 4.6 mm, 5µm column system was used for UV detection with a242 nm wavelength. The mobile phase Methanol with water (HPLC grade) (70:30) was used as the mobile phase for the technique, which was created and validated for the detection of PPD in samples of commercial hair color. With a run time of 7 minutes, a retention time of 2.088 seconds, and a flow rate of 0.55 ml/min, the method was validated over a broad linear range of 5-28 g/ml. The PPD content of hair colors may not exceed 6%. The procedures were approved in line with ICH guidelines.
