Dandruff is a common condition that affects millions of people worldwide. It is characterized by white or grey flakes of dead skin cells that fall off the scalp and onto clothes.

While it is normally not serious, the condition can cause irritation and sometimes lead to temporary hair loss. There are several possible causes of dandruff, but one that is often overlooked is seborrheic dermatitis. In this article, we will explain what seborrheic dermatitis is and how it can lead to dandruff.

What is Seborrheic Dermatitis?

Seborrheic dermatitis is a chronic inflammatory skin condition that affects areas of the body with high sebum production, such as the scalp, face, and upper chest. It can cause red, scaly patches of skin that are often itchy and uncomfortable.

The exact cause of seborrheic dermatitis is not known, but it is thought to be related to an overgrowth of yeast on the skin, an abnormal immune response, or a combination of both.

How Does Seborrheic Dermatitis Cause Dandruff?

The overgrowth of yeast on the skin that is thought to be a key factor in seborrheic dermatitis can also lead to the development of dandruff. The yeast responsible for causing seborrheic dermatitis is known as Malassezia.

This yeast feeds on the oils produced by the skin, causing an irritation that can lead to inflammation, flaking, and itching. If the inflammation and flaking are severe enough, they can result in dandruff.

What Are the Symptoms of Seborrheic Dermatitis?

The symptoms of seborrheic dermatitis vary depending on the severity of the condition and the area of the body affected. However, some common symptoms include:.

Red, scaly patches of skin
Dandruff
Itching or burning sensation on the affected area
Oily or greasy skin
Crusting or scaling

How Is Seborrheic Dermatitis Diagnosed?

A dermatologist can usually diagnose seborrheic dermatitis by examining the skin and reviewing the patient’s medical history. In some cases, a skin biopsy may be necessary to confirm the diagnosis.

How Is Seborrheic Dermatitis Treated?

Treatment for seborrheic dermatitis typically involves using medicated shampoos or creams that contain antifungal or anti-inflammatory agents. Some common treatments include:.

Ketoconazole shampoo
Salicylic acid shampoo
Coal tar shampoo
Topical corticosteroid creams

In addition to medication, it is also important to practice good hygiene and avoid triggers that can exacerbate the condition. These triggers can include stress, cold weather, and exposure to harsh chemicals or irritants.

Can Seborrheic Dermatitis Be Prevented?

While there is no guaranteed way to prevent seborrheic dermatitis, there are several steps that people can take to reduce their risk of developing the condition:.

Wash the scalp and skin regularly with a gentle cleanser
Avoid using hot water when showering or bathing
Avoid using harsh soaps or shampoos
Avoid excessive sweating or heat exposure
Manage stress levels effectively
