While drinking Papaya leaf juice is one way to achieve many health benefits, you can also apply papaya leaf paste to your scalp. All you need to do is crush fresh papaya leaves in a mortar and pestle or blitz it in the mixer. Once it has a paste like consistency, apply it on your scalp. By doing this you can easily remove the excess oil, dirt, and grime at the roots. It also nourishes and moisturises the scalp and prevents the formation of dandruff.
