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.
Process. 1  In a bowl, dilute the lemon juice with a quarter cup of coconut water. 2  Massage this mixture into your scalp for about 5 minutes. 3  Once your scalp is fully covered, work it through the length of your hair.  Leave it in for about 15 1  minutes. Wash off with a mild sulfate-free shampoo and cool/lukewarm water.
