What Causes Excessive Oil Production on the Scalp?

What causes excessive scalp oiliness? The main causes of excessive scalp oiliness include the following:

1. Genetic factors: Some patients have a family history of this condition, particularly among males.

2. Excessive androgen secretion: After puberty, increased androgen production enhances sebaceous gland activity, leading to greater sebum secretion.

3. Vitamin B deficiency: Some patients experience reduced sebum secretion after taking oral vitamin B complex supplements; thus, excessive sebum production may be associated with vitamin B deficiency.

4. Underlying medical conditions: For example, hyperthyroidism or Parkinson’s disease.

5. Other contributing factors: Such as frequent late-night sleeping, regular consumption of fried or greasy foods, and spicy foods.
