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.

Method for hair volume reduction

The invention provides a method of shaping hair comprising the following sequential steps: (i) treating the hair by topical application of a hair treatment composition comprising from 2 to 25 wt % of one or more Cmonoaldehydes, and (ii) mechanically shaping the treated hair.

Method of shaping hair

The invention provides a hair shaping composition suitable for topical application to hair, the composition comprising from 1 to 25 wt % of one or more Cmonoaldehydes and from 1 to 25 wt % of one or more urea compounds; dissolved or dispersed in an aqueous carrier.

Hair shaping composition

The present invention is directed to a method for straightening hair, wherein the method of straightening hair comprises the step of: (1) applying to the hair a hair treatment composition comprising: i) gluconolactone, in which the level of gluconolactone is from 1.5 to 5 wt % of the total hair treatment composition; and ii) citric acid, in which the level of citric acid is from 1 to 5 wt % of the total hair treatment composition; and (2) applying heat to the hair at a temperature of greater than 120&#xb0; C. for at least 10 seconds after the hair treatment composition is applied to the hair, wherein the hair treatment composition is applied to dry hair.

Method of treating hair

A method of straightening the hair comprising the step of applying to the hair a hair treatment composition comprising: i) at least 0.4 wt % of the total composition of a sugar alcohol; and ii) at least 0.4 wt % of the total composition of a bi or tridentate carboxylic acid in which the ratio of sugar alcohol to acid is 1:5 to 5:1; and iii) heating the resulting composition to a temperature of greater than 120&#xb0; C. for at least 10 seconds.

A method of styling hair comprising the step of applying to the hair a composition comprising an oligosaccharide comprising mannitol.

A hair non-permanent styling composition comprising: i) an oligosaccharide comprising 3 to 7 sugar units in which the linkage group between the sugar units is an &#x3b1;1-4 link; and ii) at least one further ingredient selected from the group consisting of a suitable carrier, a styling polymer or a surfactant.
