Apply directly to scalp. Use on wet or dry hair. Massage in for one to two minutes. Do not rinse. For best results, use daily. When applying to dry hair, make sure to detangle first in order to create clean sections to work with. Apply only as much as needed. Using the included massager on application helps stimulate the scalp, enhancing performance and experience. Massage for as long as you'd like; there are not limitations here, but the minimum would be one to two minutes.
