Denorex Medicated Dandruff Shampoos & Solutions

For over 40 years, Denorex shampoo has been used for treating and preventing itching, flaking and scaling of the scalp caused by dandruff and seborrhea. Our dandruff shampoo is an anti-seborrheic that works by slowing the production of skin cells, which helps to reduce flakiness.  

Denorex controls dandruff, psoriasis and seborrheic dermatitis and is effective in relieving dryness, itching and flaking; while added conditioners leave hair healthy, shiny and manageable.

  • What is an anti-seborrheic?+

    Anti-seborrheics are ingredients that are effective in preventing or relieving excessive secretions of sebum (an oily secretion of the sebaceous glands). Selenium sulfide, zinc pyrithione, corticosteroids, imidazole antifungals, coal tar and salicylic acid are common anti-seborrheics.

  • What is the active ingredient in Extra Strength Denorex and what does it do?+

    3% Salicylic acid is the active ingredient in Extra Strength Denorex. Salicylic acid controls the symptoms of dandruff, seborrheic dermatitis and psoriasis.

  • What is the active ingredient in the Therapeutic Denorex Shampoo?+

    There are two active ingredients in the Therapeutic Denorex Shampoo. One is a 9% Coal Tar Solution (equivalent to 1.8% w/w coal tar) that controls the symptoms of dandruff, seborrheic dermatitis and psoriasis. The other is 1.5% Menthol that helps controls scalp itch.

  • Can Denorex be used on permed hair?+

    All Denorex products are safe to use on permed hair.

  • Is Denorex Safe and Effective?+

    Coal tar/Menthol and Salicylic acid formulas are approved by the Food and Drug Administration as safe and effective for over-the-counter use.

  • Can Denorex Be Used On Colored Hair? +

    Formulas using coal tar or salicylic acid may discolor hair. Salicylic acid will strip hair dye from the porous tips of damaged hair and will most likely remain this way until the hair is re-colored.

  • Can Denorex Be Used for Continued Use? +

    Denorex can be used daily. However, if symptoms are not reduced, a physician should be consulted. Continuing long-term use of products does not cause tolerance to the ingredients. One does not build up immunity.

  • Does Denorex Cure Dandruff?+

    There is no known permanent cure for dandruff and the condition may require treatment for many years. Dandruff and psoriasis can manifest itself with symptoms that may be affected by factors such as humidity, dryness, stress, diet and other conditions. Symptoms may even be seasonal.

  • What is the tingling sensation?+

    The tingling sensation is associated with the menthol, and indicates that the product is beginning to work.

  • Can I use Denorex for open sores?+

    Denorex is not indicated for treatment of open sores. You should consult a healthcare professional before using Denorex or any over-the-counter drug other than as directed on the label.

  • Why is there a warning about cancer from the state of California?+

    The State of California established (through Proposition 65) a list of ingredients that are known to be potential carcinogens, and requires that any product distributed in California containing such ingredients show this warning. Coal tar has been found to be a possible cancer causing substance although a very large amount would have to be used for it to be a problem. The Attorney General of California has clarified the fact that inclusion in the list does not imply that the product is unsafe as used. The U.S. Food & Drug Administration (FDA) has declared that Coal Tar is one of only 2 active ingredients (salicylic acid is the other) that are safe and effective for over-the-counter use to control itchy, flaky scalp caused by dandruff, psoriasis and seborrheic dermatitis. FDA is the legal authority for all drugs (Denorex is considered an over- the-counter drug) sold in the U.S.
