Scruples MENZ 5 Minute Haircolor Activator utilizes new technology which completely oxidizes the haircolor molecule in 5 to 10 minutes. This fully stabilized developer is recommended for use only with Scruples MENZ Natural Haircolor Gel. When mixed with MENZ Color Gel, a rich, gelatinous mixture is formed and stays moist, allowing for precise color application with a bottle or a brush.
