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.
When the skin on your scalp is flaky and dry, it's tough to get through the day without itching and having flakes of dead skin fall on your shoulders. If your doctor approves, use olive oil as a natural home remedy to moisturize the scalp and prevent the flaking skin associated with dandruff and cradle cap.
