Hey man, try not to be too hung on up the grafts numbers. 3500 grafts could well be 7000 hairs with the right extraction. 4500 grafts could also be 7000 hairs depending on which hair types are extracted. Really depends on the skill of the extractor and what they’re aiming for. I’d definitely look into medication - you’d probably be surprised what could grow back after 6-12 months!
