A product release system to atomize cosmetic compositions is described, which has (a) pressure-resistant packaging, (b) a capillary-containing spray head, and (c) a propellant-containing cosmetic composition. The atomization is done using the capillary and the composition is non-fluid at 77° F. (25° C.) or has a viscosity greater than 0.0007 lb/in2 s (5,000 mPa s). The capillary preferably has a diameter of 0.004-0.04 in (0.1 to 1 mm) and a length of 0.2-4 in (5 to 100 mm). The spray rate is preferably 0.0004-0.2 oz/s (0.01 to 5 g/s). The composition can be, in particular, gel-like, waxy, or emulsion-like and used for the treatment of hair or skin.
