Ok, well if you've had it checked by a doctor and have even tried meds, then a hair system is the best choice for now. Who knows, maybe in a couple of years it will start growing again, and in that case you can just grow it out and see what happens.

You are lucky to be starting so young - I think the younger you are, the easier it is to adopt a new routine and just accept wearing as a part of life. And not to worry about it, and enjoy your new hair!
