A composition and method for grooming the hair are disclosed. The composition is soluble in water and mixtures of alcohol and water, and comprises a linear polyester derived from (A) at least one dicarboxylic acid, (B) at least one diol, at least 20 mole percent of said diol component being a poly(ethylene glycol) having the formula H--OCH.sub.2 CH.sub.2 --nOH wherein n is an integer of from two to about ten, and (C) a difunctional monomer containing a -SO.sub.3 M group attached to an aromatic nucleus, wherein M is hydrogen or a metal ion. A preferred polyester is prepared from isophthalic acid, the sodium salt of 5-sulfoisophthalic acid, and a glycol component, at least a substantial portion of which is diethylene glycol. The composition may be used in solution, or blended with other compositions for use as a mixture therewith. Conventional additives, such as plasticizers, stabilizers, etc., may also be used. Hair is groomed by applying an effective amount of the composition thereto and allowing the solvent to evaporate from the polyester while maintaining the hair in place.
