Hair looks gappy 4 months after FUE. Will hair grow and thicken? (Photo)

I had my hair transplant four months ago in Turkey. I had around 4000 grafts. I have seen hair growth on my front hairline and other parts of the Transplanted area. I know the hair is thin at first but will thicken up over time but it looks very Gappy in places. I can’t see any new hair poking out the skin in the Gappy parts could the new hair still be in the rest phase and come out at a later date. I have attached photos from before after and now. I also use minoxidil for last 3 months
