Citrus Fruits. Citrus fruits, particularly lemons, which contain vitamins A, B and C as well as calcium, phosphorus, potassium and fiber, are blood-cleansing foods.
Another great way to reduce oil production in the scalp is by breaking up the grease before it gets into your body. To do this, every morning drink 1 pint of warm water with the juice of 1 lemon squeezed in. Add to this 1 pinch of himalayan salt, and half a teaspoon of cayenne pepper.
The pads of your fingertips massage and stimulate blood flow to your scalp. If you are using oil, then dip your fingertips into the warmed oil before placing them on your scalp. Then, massage the oil into your scalp in small circles. Use only a minimum amount of oil to avoid making your hair too greasy.
