I had 4400 grafts 7 months ago (photo)

It doesn’t look like much of it has grown. What should I do now. Should I get PRP and ACell treatments offered by some doctors on the internet?

At seven months, you are seeing less that 50 percent of growth of what you can expect from your transplanted grafts. I would not expect the areas in the center to grow much more. I always tell my patients to go back and speak with their doctor as most reputable doctor will make things right financially.  A-Cell and PRP is a waste of your money at this stage.
