Thank you for posting an example pic Pan, that is awesome, yes my diffuse thinning is starting to become like yours on my frontal third, none of the meds seem to be working anymore, I am also considering H&W for their strong results, keep us updated and I hope when you do go for it you get a stellar result mate!
Edit: Oh and you should seriously consider the FUT route if you keep your hair that long at the sides, it will hide the scar, you'll get stronger results, have more donor hair for the future and less chance of transection, something to consider.
