Abstract
By incorporating cationic guar gums in combination with nonionic guar gums in a single gel composition, a highly effective, hair straightening/smoothing composition is realized which achieves the temporary straightening and/or smoothing of hair fibers, without chemically interacting with the hair fiber itself. By employing the present invention, a temporary hair straightening effect is realized which enables a wide variety of hair styles or fashions to be attained, while still enabling the hair change effect to be easily reversed by merely washing the hair to remove the chemical formulation. In addition, the physical properties of the hair fibers, such as feel, shine, luster, softness and manageability are retained without adverse effect. In the preferred embodiment, in addition to employing a cationic guar gum, in combination with a nonionic guar gum, the present invention also incorporates additives such as humidity protectors, fragrances, preservatives, pH controllers, and water.
