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, leaving only the dye taken deep into the capillary fiber. Our guess is that this situation is not a temporary reaction but that the hair color has been stripped and will remain as is until the hair is re-colored.

Can Denorex Be Used for Continued Use?

Denorex can be used daily but 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.

Why is there a warning about cancer?

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.

Why have we reduced the amount of coal tar in Therapeutic Denorex?

Therapeutic Denorex is now a dual-active-ingredient formula which is approved to both control the symptoms of dandruff and provide additional relief of scalp itch.
