EFFECTS OF SURFACTANTS ON HAIR FRICTION 199 was definitely easier. In Table XIX, friction is rising at the highest dilution, suggesting that soap solutions and shampoos containing soap require further dilution to better simulate rinsing conditions used for tresses. Additional study is needed but the procedure for measuring single fiber friction at shampoo dilutions appears attractive for critically examining shampoo compositions and predicting wet hair performance.
