PURPOSE:A cold wave first solution that is prepared by adding a yeast-separated solution from a saccharide fermentation mixture to a usual cold wave first solution mainly containing ammonium thioglycolate and an alkali, thus removing the unpleasant odor characteristic in permanent wave setting. CONSTITUTION:Yeasts are removed from saccharide fermentation mixture and the resultant solution is added to a usual cold wave setting first solution mainly containing ammonium thioglycolate and an alkali in an amount of over 0.5%, preferably 1% to give the objective cold wave first solution which can remove irritating and unpleasant odor of mercaptans, when permanent waves are set. Moreover, the use of yeast-separated solution can reduce the amount enough to completely remove the bad smell in comparison with the fermentation solution according to a known method and can greatly reduce the ammonia odor, as well, while good waves are set on hair without damaging the hair.
