Abstract

The present invention relates to a process for improved and milder permanent shaping of hair, especially human hair. It has been found that when commonly used permanent shaping compositions are mixed with another composition comprising predominantly carboxylic acids, the permanent shaping effect of the composition is improved, homogeneous permanent shaping of hair fibers is achieved and natural cosmetic properties of hair are maintained.
