White skin patches caused by vitiligo?

For the past 3 years I have noticed white patches of skin appearing on my torso. I have slightly tanned skin but usually tan quite dark in the sun which makes the patches more obvious. I've tried various reccomendations such as selsun shampoo but have noticed no change. Does anybody else have or had this problem and knows a way of helping the skin pigments grow back during this case of vitiligo? By researching the condition I have discovered it can be quite difficult to completely return to normal but I am open to any options with regards to evening out my skin to make it a bit more subtle.....
