Dandruff is the excessive flaking of dead skin that forms on the scalp, often accompanied by itching, redness and irritation. As it is normal for skin cells to die and flake off, a small amount of flaking is normal and quite common. Some people, however, either chronically or as a result of certain triggers, experience an unusually large amount of flaking. Dandruff can also be a symptom of seborrheic dermatitis, psoriasis or a fungal infection. Dandruff is a common, chronic scalp condition and can have several causes.


1. Fungal Dandruff

The most common cause of dandruff. The yeast-like fungus ‘Malassezie furfur’ is found naturally on the skin surface, however it can occasionally grow too rapidly and feed on the oils in the hair follicle, which then irritates the skin and disturbs the natural renewal of cells, resulting in dandruff to appears with itching.

2. Dry Skin

Especially common in winter when the air is cold and rooms are overheated or showers are hot. Flakes are generally smaller and less oily than other causes of dandruff.

3. Seborrheic dermatitis

A frequent cause of dandruff and characterized by red, greasy skin covered with flaky white or yellow scales.

4. Contact dermatitis

Sensitivities to certain haircare products or hair dyes can cause a red, itchy, scaling scalp. Shampooing too often or using too many styling products may also irritate your scalp, causing dandruff.

5. Infrequent shampooing

If you don't regularly wash your hair, oils and skin cells from your scalp can build up, causing dandruff.

6. Overactive sebaceous glands

Mild dandruff may be caused by overactive sebaceous glands, which are triggered by hormonal imbalance or stress.
