Tea tree oil works wonders when it comes to reducing itchiness, scaliness, and greasiness in the scalp. And all of these, in turn, can help prevent split ends. You'll need 4 drops of tea tree oil, 4 drops of almond oil, 4 drops of coconut oil and 1 teaspoon aloe vera gel. Mix these ingredients well, apply to your hair and scalp, leave it on for 1-2 hours and then rinse afterwards.
