DHI 6th month post operation result? (Photo)

Hello, I had a DHI hair transplant exactly 6 months ago. A total of 4,000 grafts were transplanted: 2,000 in the temples and 2,000 in the crown area. My question is: As seen in the pictures, even though it has been exactly 6 months, the growth in the frontal area is very weak, and in the crown area, only the hair that was present before the transplant has grown. It is generally said to wait at least 8 months for hair transplant results, but do you think this situation is normal? Thank you.
