Wet your hair thoroughly, then apply a small amount of shampoo to the scalp, adjusting the amount based on hair length. Gently massage for 1 to 2 minutes to help cleanse the scalp and stimulate circulation. Leave the lather on for another 1 to 2 minutes before rinsing thoroughly with water. Use it 2 to 3 times per week or as advised by your doctor, depending on your scalp type and hair condition. Avoid contact with the eyes and rinse immediately with water if accidental contact occurs.
