Dull Hair: Dairy
Some styling products rid your hair of moisture or shine, but dairy products actually will help rejuvenate the shine and moisture! Try sour cream or yogurt for best results. Both are cheap and easy to use! Massage a 1/2 cup of sour cream or plain yogurt in your hair and let it sit for 20 minutes. After, rinse with warm water then cool water. Then, shampoo your hair like you usually do. These dairy products will give you that moisture and shine back in no time.
