How many grafts do you think I need? (PIC)

From this picure, how many grafts do you think I need to fill in all the thinning areas? (Crown, mid and front). I am not going to lower my hairline, just want to fill in the thinning/bald areas.

Ask the doc, but I wouldn't say a lot. Looks good still. I'd also recommend propecia if you're not on it yet.
