I'm not sure how to help, but a friend of mine has hair as thin as yours, maybe thinner, and she has had it strategically colored with lots of color variations to make it look a bit thicker. That helped her some, and she also began using a powdered shampoo (aka dry shampoo, aka hair powder) to thicken up the roots. Lastly she recently cut it short into a cute pixie cut. You have such a pretty facial structure, you could totally rock a pixie cut!
