1. An aerosol device comprising:
(a) a container comprising:
at least one propellant; and
a composition comprising:
at least one fixing polymer, and/or
at least one styling powder comprising at least one water-insoluble inorganic compound,
wherein the at least one propellant is present in the container mixed with the composition or is present in the container separate from the composition; and
(b) a diffuser disposed on the container and comprising:
at least three spraying apertures for spraying a mixture of the at least one propellant and the composition in a spraying direction (Y), wherein axes of the at least three spraying apertures are parallel to each other and parallel to the spraying direction (Y);
a delivery channel configured to receive the mixture from the container; and
feed channels that are inclined obliquely relative to the spraying direction (Y) and the delivery channel, the feed channels being configured to respectively provide the mixture to the spraying apertures from the delivery channel.
