This research aimed to investigate coloring power of coating permanent agents which included kaoliang pigment depending on contents, PH respectively. We were forwarded to develop a natural coating permanent agent by including kao liang pigment, and to save time and practice economy cost. Furthermore we desired to operate hair dyeing and permanent wave simultaneously. Method we to ok to inquire was comparing coloring power of each sample which could be identified by applied natural dry and heat treatment. In consequence, it was revealed that the higher kaoliang pigment contents was the higher K/S value was, which had led to improvement of coloring power. Carrying out heat treatment than leaving as it was gave rise to improvement of coloring power. Besides, the longer the neglected time, the better the dyeing power.
