For best results, use at least twice a week, or as directed by a doctor. Shake well before use. Rub a liberal amount of product between palms and distribute throughout hair and scalp. Work product through hair & massage scalp with fingertips as you would a conventional shampoo. For easy detangling carefully comb through hair with a wide-tooth comb before rinsing co-wash from hair. Rinse and repeat if needed. Follow with conditioning.
