[0236] The compositions A to C according to the invention are in the form of a gel and are used as styling gel at room temperature (25 C.). They are applied to dry or towel-dried clean hair in an amount of 5 g of composition per head.

[0237] The compositions A to C according to the invention have a texture that results in improved usage qualities that enable good use of the gel, in particular with easier uptake and distribution. This enables good spreading of the gel over the hair.

[0238] Furthermore, these compositions make it possible to obtain high styling performance, i.e. good fixing and a long-lasting hold of the hairstyle.

[0239] The composition D according to the invention and the comparative composition E that follow were also prepared, from the ingredients indicated in the table below:

[0240] The concentrations are expressed as weight percentages of active material in the final composition.

TABLE-US-00002 Ingredients D E Acrylates/hydroxyacrylates copolymer.sup.(2) 3.8 3.8 Acrylates Copolymer.sup.(1) 1.5 Acrylates/Steareth-20 methacrylate 2.0 3.5 crosslinked copolymer .sup.(3) Triethanolamine 2.5 2.5 2-Amino-2-methyl-1-propanol 0.5 0.5 Deionized water qs for 100 g qs for 100 g pH 7.3 7.4 .sup.(1)Aquastyle SH 100 sold by the company Ashland .sup.(2)Acudyne 180 sold by the company Rhm & Haas .sup.(3) Aculyn 88 sold by the company Rhm & Haas

[0241] With the composition D according to the invention, a gel is obtained which has a texture that enables good grasping and an easy application of the product to the hair. With the comparative composition E, an excessively thick gel is obtained which is difficult to apply to the hair.

[0242] The two compositions were applied to a malleable head, the composition D having been applied to one half of the head and the composition E having been applied to the other half.

[0243] After 12 passes of a hand on each side, a persistence of the film formed by the composition D of the invention is observed whereas the film formed by the composition E disintegrated. The hair treated with the composition D is still coated whereas the hair treated with the composition E is individualized.

[0244] A better form retention of the hairstyle is obtained with the composition D than with the composition E.

[0245] The composition D of the invention therefore makes it possible to obtain a styling gel that has an improved resistance to mechanical friction.
