Grayban is an easy-to-use spray that helps you lose your gray naturally. It doesn't dye your hair. Instead it combines with your scalp's natural proteins to bolster melanin pigment, restoring your original youthful hair color. Simply apply 2-4 pumps to dry hair once a day and when desired results are achieved, reduce treatment to 2 times per week. Great for root touch ups or a full head of hair. Safe and chemical free. 8 oz. bottle.
