(3) The compositions prepared above 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.

(4) 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).

(5) A level of fixing with composition A according to the invention equivalent to that obtained with composition B is obtained. The fixing is also longer-lasting with composition A according to the invention than with composition B. The fixing hold in wet medium is also improved with composition A according to the invention relative to composition B.

(6) Moreover, a much smoother feel of the hair is obtained from the start of drying of composition A, and even more so after drying.
