6 experts · Strong agreementWhat the gurus are saying
Selsun Blue's selenium sulfide is the ingredient these experts keep returning to, because it works on the yeast behind flaky, itchy scalp. Several reviewers find it a little drying, so those with a dry scalp rather than dandruff may want to watch how their skin feels. The scent has been called a touch strong, but the product does not irritate everybody. Leave it on for about five minutes before rinsing.
