I agree with bombscience; however, you could still apply the conditioner to the ends of the hair provided you're careful not to let it touch the scalp. Rinse immediately after applying and your hair won't feel stripped.
Shampoo...rinse...condition...rinse...repeat as necessary. Nizoral isn't a wonder drug...just a shampoo. Let it sit for 3-5 minutes while washing and you're good to go. Don't gotta be all hyped bout it.
