Abstract: The present invention is in the field of hair treatment compositions; in particular relates to hair treatment compositions for hair volume reduction. Despite the prior art, there still exists the opportunity to increase the conditioning benefits delivered through hair treatment compositions. It is therefore an object of the present invention to provide a hair treatment composition that retains shape and reduces frizz even after exposure to humidity and washing the hair. It has been found that reduced hair frizz and hair shape retention even after exposure to moisture can be obtained by using N-formyl amino acids.

Abstract: A method of repairing oxidatively-treated hair, the methods comprising the sequential steps of: (i) soaking hair in an aqueous treatment composition, (ii) rinsing the hair of step (i); characterised in that the aqueous treatment composition comprises 0.1 to 6 wt % N-acetyl amino acid, based on the total weight of the composition, wherein the N-acetyl amino acid is selected from the group consisting of N-acetyl glycine, N-acetyl alanine, N-acetyl proline, N-acetyl leucine, N-acetyl isoleucine, N-acetyl valine, N-acetyl tyrosine, N-acetyl phenylalanine, N-acetyl tryptophan, N-acetyl serine, N-acetyl glutamine, N-acetyl threonine, N-acetyl asparagine, N-acetyl methionine, N-acetyl lysine, N-acetyl histidine and mixtures thereof, gives damage repair benefits.

Abstract: The invention provides a method of strengthening the fibres of hair, the method comprising the sequential steps of: (i) washing the hair; (ii) soaking the washed hair in an aqueous treatment composition, and (iii) drying the soaked hair; characterised in that the aqueous treatment composition comprises at least 1% N-acetyl lysine (by weight based on the total weight of the composition). The invention also provides the use of an aqueous treatment composition comprising at least 1% N-acetyl lysine (by weight based on the total weight of the composition), for the strengthening of hair fibres.

Abstract: The invention provides a hair shaping composition suitably for topical application to hair, the composition having a pH of 4 or less and comprising, in an aqueous continuous phase: (i) at least 0.5% by weight based on the total weight of the composition of a first component selected from D-glucono-?-lactone, D-glucono-?-lactone, D-gluconic acid and mixtures thereof; (ii) at least 0.1% by weight based on the total weight of the composition of a second component selected from glyoxylic acid, glyoxylic acid hydrate, salts thereof and mixtures thereof; in which the weight ratio of first component (i) to second component (ii) in the hair shaping composition ranges from 10:1 to 1:10.
