Abstract: A hair spray assembly is provided to substantially limit and confine the divergence and radial projection of spray emanating from a shower head into a generally cylindrical spray zone and to substantially prevent splashing and dripping of the water spray outside of that spray zone. This invention is particularly useful for professional hair care and treatment, such as permanent waving, frosting of the hair and shampooing and structurally includes a portable nozzle having a body with a diverging mouth that defines an outlet and a tubular inlet that telescopes into a flexible hose. A shower head having an annular flange is secured to the body of the nozzle and includes an apertured disc that covers the mouth of the nozzle and a rigid rim portion that extends axially forwardly of the apertured disc. A waterproof annular skirt engages the shower head and includes a lip portion that extends axially forwardly of the rigid rim portion.
