Abstract
Hair spray compositions containing a carboxylated polyurethane resin, and having a low volatile organic content, are disclosed. The compositions have a low viscosity, and can be applied as a pump spray or as an aerosol, to hold the hair and impart excellent hair set retention properties. The hair spray compositions can be used with a curling iron or a blow dryer to style the hair.
