I've had this discussion several times before and gone in to those details.
But they're irrelevant really because no surgeon will guarantee you results and there is no way to gauge and quantify someone's expectations.
So its all subjective and therefore pointless to debate.
I can only speak from my personal experience and from having seen recent results first hand.
I don't want to dissuade anyone from looking into it or ultimately having surgery, if thats what they want.
But I am suggesting caution and FULL research before having a procedure, because good results are not dependant upon having enough finances and its not the miracle cure many people think it can be.
I speak for myself when I say that I know a hair piece gives me a more natural, less detectable result than any surgeon could give me.
If that wasn't the case, I'd be under that knife quicker than you can say toupee!
