FUE Hair Transplant

I had 800 grafts to my hairline, roughly 16 cm long and longer cm deep. It's supposed to be 50 FU per cm^2. I was about NW2.5 before surgery, my aim was to be restored the an NW2 with decent density. I'm not sure what to expect at this stage, but the hair density looks very low and see through. I don't think thickening alone will make this look good, I'm hoping the hair density will double as well as thickening. Can I expect much new hairs to sprout? Or at this stage are most of them up and just going to thicken? Pictures taken directly under a light and away from the light for contrast.
