8 months after hair transplant, disappointed with results. Will this improve? (photo)

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor.

You should continue to use Rogaine & Propecia if possible. After one more month, consult with your surgeon. If you wish a second opinion, I recommend a member of ISHRS ( ISHRS.org).

It's not possible to discern your results without knowing where you started, the procedure done, and your aftercare routine. This is exactly the time that you should be seeing your surgeon in person to help clarify all of this and more. Don't underestimate limitations to surgery and the high percentage of patients who really need 2 or more surgeries to accomplish the results they're looking for. Call your surgeon for an appointment. 

Thank you for sharing your pictures, I think you should discuss your concerns with your plastic surgeon. Let him do the assessment and advice you what best can be done. 

I always tell patients that their recourse is to speak with their surgeon if they are every disappointed in their hair transplant results. Good surgeons care about patient results and their satisfaction and it is their surgeons that set the expectations that are needed. The discussion with your surgeon is not and should not be confrontational. It should be a cordial meeting where you can discuss what you are seeing on your head and what expectations you had going into the surgery. Sometime, the results fall short and if is the case, try to find out why that happened and if you both communicated properly on the expectation issue.
