Hair conditioning compositions have been long known and are very popular among users, particularly female consumers. The hair conditioning compositions are usually applied after hair cleansing, dyeing or waving processes. Above all, the hair conditions compositions are used to restore hair structure, improve lustre and touch thereof, ease combability of wet and dry hair, and provide a lasting hair style.
The number of active substances suggested for this purpose is immense; reference is, e.g., made to the monography of K. Schrader, "Grundlagen und Rezepturen der Kosmetika", 2nd Edition (1989, Huthig Buchverlag, Heidelberg), pp. 722 to 781.
Known hair conditioning compositions still require improvement, despite of the multitude of known and suggested formulations, especially with regard to their ability to penetrate into the hair.
