What is Dandruff?

Contrary to what many people think, dandruff is not caused by a dry scalp. It appears when the rate at which dead skin cells are shed and replaced begins to speed up. The normal rate at which all of the skin over the scalp is generally replaced is at a rate of once per month. However, with dandruff, this rate is accelerated to once every 10 to 15 days. For people with severe dandruff known as seborrheic dermatitis (seborrhea), this rate is accelerated even further.  The result is white flakes that can accumulate on the hair, shoulders and clothing accompanied by an itchy scalp.

The fungus Pityrosporum ovale (P. ovale) is often implicated in dandruff. P. ovale is a common and naturally occurring yeast-like organism found on the scalp and other parts of human skin. In small numbers, the fungus causes no harmful effects. But, certain triggers including changes in climate, hormonal or stress levels, can cause an accumulation of the P.ovale fungus on the scalp. The scalp contains the largest concentration of sebaceous (oil) glands.

Dandruff tends to be limited to the scalp , but severe dandruff, or seborrheic dermatitis (seborrhea), can spread beyond the scalp to areas around the eyebrows, cheeks, behind ears or on the chest. Seborrhea usually appears as  oily yellow flakes and moist red patches on the scalp.

Nizoral 2% Shampoo Is Effective Treatment

A number of topical creams, lotions and shampoos are used to manage the symptoms of dandruff. These include ingredients such as salicylic acid, coal tar, zinc pyrithione, selenium sulfide and sulfur. They all work in different ways but only Nizoral shampoo contains ketoconozole, an anti-fungal agent tha can kill the P. ovale fungus that contributes to dandruff.

The first step in using Nizoral shampoo is to reduce the amount of P. ovale on your scalp to normal levels. Start by using Nizoral twice a week for the first two to four weeks. On non Nizoral days, use your regular shampoo and conditioner. Apply one to two teaspoonsful of Nizoral to wet hair and work it into a lather. For best results, leave Nizoral in contact with your scalp for three to five minutes. Then, rinse thoroughly.

The second step is to prevent dandruff from returning. Use Nizoral shampoo once weekly to keep dandruff away. Follow the same instructions as above and keep using your regular shampoo and conditioner between uses.


Precautions With Nizoral

Nizoral shampoo is not designed to be used with other medicated shampoos or creams. Combining multiple medicated treatments may increase scalp irritation potentially cause interactions between the different medications. Check with your physician or pharmacist if you wish to combine two or more medications at one time.

Nizoral shampoo may cause discoloration of chemically coloured hair but this is very unusual and not typically associated with its use. However, as a precaution, test it on a small patch of hair at  the back of the head before treating the entire scalp.

Nizoral shampoo’s safety and effectiveness has not been determined in children under 12 so it isn’t recommended that children use Nizoral.
Although the topical application Nizoral shampoo doesn’t cause detectable levels of ketoconazole in the blood, as with any medicated product, pregnant or nursing women should NOT use Nizoral shampoo unless recommended by their doctor.
