Sebulex Dandruff shampoo helps control dandruff, gives fast relief of itching and leaves your hair manageable. It also doesn’t smell bad. Some dandruff shampoos have an overpowering unpleasant scent. Sebulex smells sort of like dishwashing soap. This makes it a fairly nice alternative. The active ingredients in sebulex include 2% Sulfur and 2% Salicylic Acid. Eventually, you will only need to use Sebulex 1 to 2 times per week. At first, if you are switching shampoos or are having some problems with itching and scaling you might want to use Sebulex every day. Sebulex often clears up your initial problem in 2 to 3 treatments.
