Abstract

The hair treatment compositions are in a variety of forms including permanent shaping compositions, oxidative after-treatment compositions, hair fixing compositions, hair bleaching compositions, hair cleansing compositions, hair care compositions or hair dye compositions containing direct-dyeing dye compounds and/or a combination of at least one developer and coupler and are characterized by 0.1 to 35 percent by weight of at least one dendrimer, preferably a poly(iminopropane-1,3-diyl)-dendrimer with nitrile and/or amino end groups. Methods of hair treatment based on these hair treatment compositions are described.
