Refresh your look with JUST FOR MEN color and an easy, no-mix routine. Simply attach the comb applicator to the pre-mixed tube, comb color where you want it, wait 10 minutes, then rinse. The patented Autostop formula stops coloring after 10 minutes, while the comb helps target gray or cover all over. The ammonia- and peroxide-free formula provides coverage from roots to ends, with color that lasts up to 8 weeks as hair grows back. Follow package directions and complete a skin allergy test 48 hours before use.
