There is always hope. I'm sure you know you've left it pretty late to start meds, although that doesn't mean you won't see some success.
Stick with it you never know what lies ahead. If you have plenty of minituarized hairs about or revivable folicles then they can potetially all regrow strong n long.
You could thicken up that middle scalp area and your crown somewhat, no idea by how much and could possibly close the gap on your hairline island area.
It all depends on you as a person and your responsiveness to meds.
