Darkly, you have pretty nice hair now. Have you considered just keeping a great regimine, perhaps scalp excercises and hair-related nutrition (soy and flax) and waiting for gene therapy and cloning? 5 more years and we may all be able to have headfulls of hair on command, who knows.
I had transplants behind my hairline ten years ago. Wish I hadnt. Have lost about an inch at the temples since and have visible plugs now, so I have to comb hair forward. Knowing what I know now, I proboably could have kept that hair from receeding in the first place (I was only using propecia for years) and not propecia, nizoral, soy, flaxseeds daily, big vitamin intake, staying away from saturated animal fats, scalp excercises, electromagnetic therapy, gentle shampoos, green tea. I didnt know squat then.
The thing about surgery man is this,,,,,,,,,,,,,,,,,,,youre always wondering if youre receeding behind it. Your wondering if youre one of those guys who will have a small hippocratic wreath at 55 years of age and end up looking silly with a see through connected combover. Getting a buzz cut will be a non-option with the scar also unless you opt for an expensive FUE. If guys just stopped getting transplants period, I bet the industry would double down their efforts to genetically solve male pattern baldness or find a cloning method that really works also.
I also feel the need to say that you have a great face. Hell, youre a good looking chap even at NW2. Im sure youre not struggling with the ladies. Anyhoo........I hope whatever you decide turns out well and best wishes.
