Are there any animal products in any of the Selsun Blue shampoos?
Although most of our ingredients are synthetic or plant derived, we cannot guarantee that none used in our Selsun products are derived from animal by-products.
How long should I leave the product on my hair?
For our Selenium Sulfide products, it is recommended that you let the shampoo stay on your head for approximately two (2) minutes. This allows the suspension system to break and the active to fall onto the scalp. For Selsun Blue Daily Care and Naturals there is not a specific time that you have to leave the product in your hair.
