Causes of Dandruff

The cause of dandruff is usually due to the overworking of the sebaceous glands. These glands produce oil and help shed dead skin. In the case of a dandruff sufferer, the sebaceous glands are overactive, shedding more skin than usual.


Hormonal imbalance.

Poor health.

Poor hygiene.

Allergic hypersensitive.

Lack of rest.

Emotional stress.

Nutritional deficiencies, for example, a lack of vitamin B or essential fatty acids.

A diet high in sugar refined carbohydrates, fat and starch.

Heredity predisposition.

Excessive use of hair sprays and gels.

Improper use of hair-colouring products or excessive use of hot hair curlers or curling irons.

Cold weather and dry indoor heating.

Stress and anxiety.

Infrequent shampooing of the hair or inadequate rinsing of the scalp and hair.

Many people think that flaking occurs because their scalp is too dry, and stop using shampoo because they believe it makes the condition worse. This is not true. The flaking occurs due to the increased turnover of skin cells.

An overgrowth of yeast fungus (pityrosporum ovale) can lead to dandruff. The condition may improve in the summer and get worse in winter, because UVA light from the sun counteracts pityrosporum ovale.

Not brushing the hair regularly to allow for normal shedding of dead skin cells can also result in dandruff.

The rate of shedding is increased if the scalp is already inflamed or itchy
