Causes of Dandruff
The skin of the scalp (and also of the whole body) is constantly renews itself by shedding the outer layer of skin cells. Most of the time this shedding is unnoticeable. But when this shedding becomes noticeable on the scalp, it is called dandruff.
Mild dandruff occurs not due to dryness of the scalp but usually is a result of too much oiliness of the skin. If you have large size flakes together with symptoms around your nose, eyebrows, ears, around your navel or genitals, it may be due to seborrheic dermatitis or seborrhea. Severe dandruff may be the result of psoriasis of the scalp. Seborrheic dermatitis may be caused by an increased number of a yeast-like organism (pityrosporum ovale) found on healthy scalp in low numbers. Dandruff can occur to anybody at any age. It should not be left untreated.
Zinc and essential fatty acids (pumpkin seeds, nuts, vegetable oils) prevent dandruff.
