The case of dandruff is not know, but medicine has a few theories on why some people develop dandruff:
Increased oil production and skin secretions
One theory proposed is that increased oil production on the scalp especially can trigger shedding of dead skin cells, which produces the white flakes known as dandruff. Oily skin which is a result of an overactive sebaceous gland may be another factor.
Increased numbers of normal skin yeasts
Some people have a genetic disposition to have increased levels of the pityrosporum ovale yeast on their scalp, which can cause dandruff symptoms.

Hormonal changes
Studies show that some women who are menopausal may have dandruff due to the changes in their hormones, that normally protect the scalp from this condition.
Lack of sunlight
Dandruff may get worse in winter than in summer because the ultraviolet light kills the pityrosporum ovale yeast that can cause dandruff.
