I am now one year since my transplant (photo)

Although the front looks good, the back does not look as good as I expected. What do you recommend?

What you got now is about what you will get and no more. Usually all of the grafts have grown out in a year? If you want more density, you will probably have to meet with your surgeon again and ask for a second surgery for the crown or consider Scalp Micropigmentation (https://scalpmicropigmentation.com/gallery/thinning-hair/#!https://scalpmicropigmentation.com/wp-content/uploads/2016/04/scalp_micropigmentation-new_hair_institute-042-thinning_hair.jpg).
