You’re not alone if you are struggling with hair loss and dandruff. Dandruff is a common scalp problem wherein the dry skin flakes off in small whitish/oily pieces.According to the American Academy of Dermatology 80 million Americans suffer from hair loss and thinning*. Similar numbers exist worldwide. 

Understanding the cause of dandruff

Dandruff can be due to dry scalp or seborrheic dermatitis. Seborrheic dermatitis is a troublesome condition wherein the scalp is infected with fungal colonies by a fungus called Malassezia. Excess skin oil (sebum) contributes to dandruff too. Men who are post-pubertal age with poor hygiene are susceptible.

Men are more prone to dandruff and seborrheic dermatitis than women due to the larger size of the oil glands on the scalp that produce more sebum*. The male hormone (androgen) is responsible for these oil glands that become overactive during puberty.  Overactive oil glands along with poor hygiene and fungal colonization result in dandruff.

Other factors contributing to dandruff can be nutritional deficiencies, genetics, stress, immunity and environmental factors.Other skin conditions like psoriasis can also mimic dandruff and it is, therefore, necessary to consult a specialist. Fortunately, products containing ketoconazole help in dealing with these important issues. 

What is ketoconazole?

Ketoconazole is an antifungal agent which came into medical use in 1981. It is an imidazole compound and like other antifungals of this group, has a wide spectrum of use. It not only comes in the form of the oral medicine but is also available in creams, gels and shampoo formulations.

How does ketoconazole work?

Ketoconazole acts by inhibiting fungal cell growth. Other agents like salicylic acid, coal tar, and zinc pyrithione are also used for the treatment of dandruff, alone or in combination forms. Also, a small study (conducted on 15 subjects) suggested that ketoconazole promotes hair growth or reduced hair loss. For better understanding of the mode of action of ketoconazole, refer to the image below. This image summarises the causes of flaky, itchy and oily scalp. Ketoconazole not only targets the fungal colonization, but also works on the oil buildup on the scalp.

While 2% is prescription strength, 1% is available in the market and pharmacies. Fortunately, 1% ketoconazole shampoos help in dealing with not only dandruff but other important issues like hair loss.
