Watch the Temperature of the Water
Hot water is going to get rid of your natural hair oils (sebum) and by getting rid of that protective barrier, you really are getting rid of the oils that contribute to shine. Don’t worry, you don’t need to stand there shivering in a cold shower. Just use luke warm water to wash your hair. While you wash your hair always use those fingers to massage and stimulate your scalp circulation.
Use Essential Oils
Mix an essential oil into your shampoo or conditioner: add jojoba or almond oil. All you need is about 1 tbsp of each into an 80z bottle.
