Comparison of Wiping Methods for the Removal of Cleaning Agent Residue from Hair Follicles

The study, involving 18 healthy male volunteers aged 21-22, investigated whether different wiping methods would leave varying amounts of cleaning agent residue in hair follicles compared to a standard washing method. The participants were divided into three groups, each using a different wiping method, to remove a cleaning agent marked with fluorescein sodium salt from their hair. Fluorescence intensity was used to measure the residue. The findings indicated that there were no significant differences in the amount of residue left behind by the different methods (P = 0.67 for hair root, P = 0.62 for hair bulb). Thus, the study concluded that wiping methods are as effective as washing in removing cleaning agent residue from hair follicles.
