A composition that protects the hair from thermal damage and doubles as an excellent hair styling aid, in the form of a hair spray, mousse foam or gel composition, and method of applying the composition to hair prior to substantial configuring of the hair in its final configuration. After application of the composition to wet or dry hair, prior to styling, the applied composition, including a polymer having a Tg less than about 120°C, is heated to the glass transition temperature of the polymer, while the hair is in the desired configuration, and thereafter the heat is removed from the polymer to cool it to a temperature below its glass transition temperature to harden the polymer in a shape complimentary to that of the desired final hair configuration. The thermoplastic polymer fixative may include a plurality of sulfonated dicarboxylic acid moieties and/or neutralized sulfonate moietie. The composition includes a water and/or alcohol carrier, and a water-soluble or alcohol-soluble thermoplastic fixative polymer or resin in an amount of at least about 0.1% up to about 20% by weight of the composition, but below a level at which adjacent hair shafts are adhered together, and preferably, in an amount in the range of about 0.5% to about 4% of the composition, particularly about 0.5% to about 3% by weight of the composition.
一种可保护头发免受热损伤并可作为极佳的头发定型辅助工具的组合物,其形式为头发喷雾、摩丝泡沫或凝胶组合物,以及在头发最终定型前将该组合物涂抹在头发上的方法。将组合物涂抹在湿发或干发上后,在定型之前,将涂抹的组合物(包括 Tg 小于约 120°C 的聚合物)加热到聚合物的玻璃化转变温度,此时头发处于所需的形状,然后从聚合物上移除热量,将其冷却到低于其玻璃化转变温度的温度,使聚合物硬化成所需的最终头发形状。热塑性聚合物固定剂可包括多个磺化二羧酸分子和/或中和磺酸盐分子。组合物包括水和/或醇载体,以及水溶性或醇溶性热塑性固定聚合物或树脂,其用量至少为组合物重量的约 0.1%至约 20%,但低于相邻发轴粘在一起的水平,优选用量为组合物重量的约 0.5%至约 4%,特别是约 0.5%至约 3%。
