THE METHOD OF COLD WAVING HAIR WHICH COMPRISES TREATING THE SAME WITH A WATER-SOLUBLE BISULFATE AND A WATER-SOLUBLE CATIONIC THERMOSETTING RESIN OBTAINED BY REACTING A POLYALKYLEENE PLYAMINE HAVING TWO PRIMARY AMINE GROUPS AND AT LEAST ONE SECONDARY AMINE GROUP WITH A DICARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF DIGLYCOLIC ACID AND C3-C8 SATURATED ALIPHATIC DICARBOXYLIC ACIDS TO FORM A WATER-SOLUBLE, LONG-CHAIN POLYAMIDE CONTAINING SECONDARY AMINE GROUPS, THE MOLE RATIO OF POLYALKYLENE POLAMINE TO DICARBOXYLIC ACID BEING FROM ABOUT 0.8:1 TO ABOUT 1.4:1, AND THEN REACTING THE POLYAMIDE IN AQUEOUS SOLUTION WITH EPICHLOROHYDRIN IN A MOLE RATIO OF EPICHLOROHYDRIN TO SECONDARY AMINE GROUPS OF SAID POLYAMIDE OF FROM ABOUT 0.5:1 TO ABOUT 1.8:1.
