Brush in. 5 minutes. Shampoo out. Always remember to do the 48-hour skin allergy test before use. Shade Selection Tip: Can't decide between 2 shades? Try the lighter one first. You can always go darker later. Only have a little bit of gray? Go with a lighter shade first for the most natural look. Getting some gray head hair, too? Try just for men autostop or original formula in the same shade.
