On unoiled hair, shampoo once. On hair with oil or nutrimask, shampoo twice. Safe for everyday use. But we recommend to NOT shampoo more than 2-3 times a week. After rinsing out shampoo, apply the conditioner on hair strands and keep for a minute. Avoid using on scalp. Rinse off with plain water. Patch test on a small area of scalp prior to first use." "
