HOW TO USE: Shampoo and towel dry. Wear plastic gloves. Shake can well before use. Point applicator nozzle down and dispense an egg-size amount of foam into the palm of the hand. Apply through the hair from the roots to ends evenly. Repeat until the hair is adequately covered. Comb through, leave for between 5-20 minutes. A deeper, lasting result will be achieved with longer development times. Rinse thoroughly and style as normal.
