Abstract
A hair conditioning and styling pad is provided which comprises a shaped body of a resilient, open-celled, hydrophilic polyurethane foam matrix integrally incorporating an aqueous phase incorporating about 70-90% water, about 5-25% of a hair conditioning agent, and a nonionic surfactant. The pad is preferably affixed to the tines of a styling brush or comb to yield a composite brush or comb which is effective to condition and style hair.
