Use hair serums, they add shine and add oil to hair. Also you can use olive oil, and coconut oil is great. I recommend to do regular hot oil treatments, like 3 or 4 times a week. You can buy hot oil treatments (like V05 hot oil treatment) or you can use some olive oil or coconut oil. Just put some oil in a mug, heat it in the microwave for 25 sec or so, put it all over your hair while messaging your scalp. Wrap saran wrap around your head, then put a warm towel over top and let sit 15min-a couple of hours. If you dont have time for all of this blow dry your hair on a low setting to add heat and let sit in a bun. Make sure you wash your hair twice after to get all the oil out. Also you can do deep conditioning treatments. I do both of these and they really make my hair shiny and healthy looking. Hope this helps.
