Will my donor area after my hair transplant improve? It still looks terrible after 4,5 months (Photo)

I had a hair transplant approximately 4,5 months ago, and I'm seriously starting to get worried about my donor area. 3 weeks post operation there was a whole pattern on the back of my head. After 4,5 months the pattern is still somewhat visible after shaving it down. I still have many bald patches on the back of my head, and even many red spots in the lower area. I guess the area is still somewhat irritated. Is there anything I can do to improve the situation?
