It can also affect the ears, eyebrows and forehead. If this is the case check with your dermatologist because the treatments will be different than for the traditional dandruff discussed here. Causes The primary cause of dandruff is thought to be a yeast called Pityrosporum ovale . Over activity of oil glands is another possible cause. A high sugar intake may be another major cause.
Sugar requires B vitamins in order to metabolize and can cause a deficiency.
To compensate take a high potency B-complex to relieve the dandruff. Related to the sugar problem is the fact that diabetes may be the cause of your dandruff. If you have diabetes the high sugar levels result in dehydration of the tissues as the body flushes out fluids in an attempt to rid itself of the sugar. One of the end results is dry skin. Shampooing in hot water may strip out the natural oils and dry out your scalp.
