Abstract
A hair treatment composition including a non naturally-occurring keratin protein in combination with a hair treatment formula is described. The protein is preferably of human origin and has not been previously cross-linked. The protein is most preferably selected from the group of soluble keratin proteins found in human hair. Preferably, the composition contains one, preferably at least two allelic variants of the protein, most preferably in substantially the same ratio at which they are found in hair of a selected individual. The individual may be selected, for example, on the basis of having appealing hair, of being the future user of the hair treatment composition of other reasons.
