The conditioner bars are 2 oz. They work great and last a long time. So convenient when traveling! Just rub the bar directly on the hair, especially in the ends, comb your hair, leave it on for a minute, then rinse. You may also reapply a tiny bit after you are done rinsing and leave it on. Important to keep it dry between uses.
