Unfortunately, fine, thin hair is the most prone to looking oily. If you have this problem, wash your hair daily with a mild shampoo that does not contain conditioners -- usually labeled "for oily hair" or "clarifying"; these will leave the least amount of residue. Then use a very light creme rinse or conditioner only on the ends of your hair, if needed, and be sure to rinse thoroughly. Avoid all products containing silicone, oils or lanolin, as well as two-in-one products. During the day, a quick combing can help redistribute oils and reduce that stringy appearance. Or, for more a more serious case, spritz a little water on your hair and blow-dry it using a comb to remove and redistribute oils -- the heat of the dryer will make the oils more liquid and easier to manipulate.
