Described herein is an aerosol hairspray product including a container including a container wall which encloses a reservoir. The reservoir includes from about 40% to about 70% of a hairstyling formulation and from about 30% to about 60% of a dimethyl ether propellant. The hairstyling formulation includes water, one or more hairstyling polymers, and from about 0.05% to about 2% alcohol. A spraying device is attached to the container. The spraying devices includes a valve including a valve housing including a vapor tap including a vapor tap area. A dip tube is connected to the valve. The dip tube includes a dip tube orifice including a dip tube orifice area. The ratio of the vapor tap area to the dip tube orifice area is from about 0.005 to about 0.15.
