Hi Carl, It looks like you are a good candidate and SMP could really help you hide the scars and thicken all up.
If it was FUE you had back in Feb there is no need to wait longer, FUE scars are usually ok after 3 months and while the implanted area will of course grow much hair its certainly possible to help you by filling in and creating a more even look, as long as all is done carefully there should be no issue.
