I would like a second opinion, why didn't they put grafts in the middle even though I am thin there? Will PRP work? (Photos)

Hello ;

First of all, thank you for your questions and photos.
I don't think there's any error in your hair transplant, because they planned to fill the anterior region for a start. my opinion is that you need a 2nd session. If there are donors in your nape region that can be handed to the second session (I couldn't see the photo of the nape region), you can perform a densification study in the second operation.
Kind Regards

You do have hair follicles present on the top of your head, so PRP could help. PRP with stem cells would be even more helpful but it may not work for everyone. HT is much more reliable and more permanent. I would have waited on the transplant until I saw how you responded to the PRP and then performed the transplant, that way you could have had the top treated as well if needed. It looks like you may need a second procedure to treat the top so that it matches the front. 

First of all, what was the surgery plan initially? What did you speak with your surgeon? Did they deliver something different than discussed? Or was the crown never mentioned?
You still have a lot of native hairs, but they look weak. A penetration to scalp at this stage could have caused a permanent loss on some of your native hairs and you may have not looked different than how you are now. This can be one reason why they didn't want to do work.

Hello,
Both DHI and FUE methods are good, the difference is that with DHI grafts applied directly to the receipent area with Choi Pens without shaving the hairs. Both DHI and FUE have successful result.

Hello and thank you for your question. You have a good question, I’m not sure why your crown wasn’t done. You might look for a second opinion in person consultation. Best wishes. Dr. T

When I examine and look carefully to your photos I have to say that you would have  benefit with HT for top area, because there is  enough hair thinning to restore. If you decide to have a hair restoration surgery, density of the area will  increase resembling natural hair, and you  have no risk of permanent hair follicles damage. PRP sessions would not reverse the thinning, and does not work  for  AGA.

It seems like the focus was to build the anterior hairline. If your goals were to also have coverage then that should have been taken into consideration with the surgical plan and enough grafts should have been taken to also transplant the front/mid scalp. It is not uncommon for patients with significant hair loss to require multiple procedures to achieve their goal.

As per the pictures the transplant is done well. When a person still have some good amount of existing hair then the priority is always to make them better and denser that's because we have limited donor which should be use wisely and hair transplant is just a camouflage of fullness and not a hair to hair replacement.  Also I would like to add that transplant at this stage could have caused a permanent loss on some of your native hairs. So surgeons needs to wait to see how you are responding to Medical treatment first if medicines are off your table then the hair transplant should be planned. 

You should ask your surgeon why they did not transplant the top of your head. PRP will not grow hair, see below
