Dandruff / Seborrheic Dermatitis – What is dandruff ?

The cells of the skin shed continuously to form new skin (but invisibly), including the skin on the scalp. This is discerned as scales on the scalp. However, excessive skin shedding can lead to dry, white flakes, commonly known as dandruff. 

Seborrheic dermatitis is a more severe form of dandruff, often accompanied by itching,  redness and inflammation.

How does Dandruff occur ?

One can have mild asymptomatic scaling of scalp to severe redness and thick greasy itchy scales. Besides the scalp, other common sites include face (eyebrows, corners of nose, beard), ears, eyelids,chest, upper back, armpits, groin, under the breasts.

Why does Dandruff occur ?

There are multiple factors which can cause dandruff :

• It is caused by an overgrowth of a fungus Called Malassezia, which lives on the skin.
• Excessive oil secretion from the glands or a change in oil composition can contribute. This can also favor the growth of the fungus. 
• Dehydration causing flakes – which happens in cold weather. 
• Lack of certain micronutrients like zinc , vitamin D, omega acids can lead to excessive scaling. 
• Stress, Sleeplessness, hormonal imbalance and a lack of healthy diet are major aggravating factors.
• Associated with certain skin and neurological diseases. 

Who can be affected by Dandruff ?

Dandruff can affect people of any age – from infants to old people. But, hormonally active ones (reproductive age group) are the most affected. The reason as to why it occurs differs in each of the age groups.
