[0146] For each composition 1 to 14, a comparative composition not comprising any polymer was also prepared.

[0147] The aerosol compositions 3, 4 and 10 to 14 prepared above and also their respective comparative compositions were introduced into an aerosol dispensing device which has the following characteristics:

a valve equipped with a nozzle with an orifice 0.41 mm in size and an internal orifice 2.03 mm in size,
a diffuser equipped with a turbulent-channel nozzle whose orifice is 0.38 mm in diameter.

[0148] 1.5 g of these aerosol compositions were sprayed onto 5.4 g locks of dry hair laid out in a fan shape (spraying on both sides).

[0149] A level of fixing with the compositions according to the invention greater than or equal to that obtained with the comparative compositions is obtained. The fixing is also longer-lasting, or equivalent, with the compositions according to the invention than with the comparative compositions. The fixing persistence in wet medium is also improved with the compositions according to the invention relative to the comparative compositions.

[0150] Moreover, a much smoother feel of the hair is obtained from the start of drying of the compositions according to the invention, and even more so after drying.
