Hey there! I had a similar concern when I had my hair transplant a few years ago. My donor area also looked patchy for a while, but it did eventually recover. It took about 6-8 months for the hair to fully grow back in that area.
I was worried at first, but my surgeon reassured me that it's a common part of the healing process. Just make sure to follow your post-op care instructions and be patient. If you're still concerned, it's always a good idea to follow up with your surgeon to get their professional opinion. Good luck!
