Abstract: Compositions including polycarbodiimide and derivatives thereof together with one of water soluble polyacid and poly carboxylic acid compounds and derivatives thereof to enhance the quality of the keratinous substrates. The present invention relates to a cosmetic treatment and process for treating keratinous materials, in particular for hair-care and hair-styling, where, according to the process, the polycarbodiimide and water soluble polyacid and poly carboxylic acid actives may be applied in a treatment that is a single step emulsion. The composition can include from about 0.2 to about 5.0%, by weight, of the composition of a combined amount of the polycarbodiimide and the polycarboxylic acid in amounts sufficient to impart hydrophobicity to keratinous substrates, including hair fibers, upon application thereto. It is in particular a hair treatment composition and process for enhancing durable non-permanent shaping and curling of the hair, particularly under conditions of one or more of high heat and high humidity by enhancing crosslinking in the hair, thereby maintaining the style properties of the hair, and retaining or enhancing the feel and the ability to comb the hair.
