If you have a decent hairline intact (nw2 and below) but you're diffuse thinning, I think you should get on meds to stabilize, and even if your donor area is not great you should get 2-3k grafts to reinforce the top
you won't have amazing hair but there's a huge difference between being able to rock a decent head of hair and only have it look like shit while wet like here:
