To answer your question, I do understand that restoring hair is an ongoing adventure and is practically impossible to predict when, if ever, it will stop.
This is why I am considering the FUE approach rather than FUSS. As it is my understanding that the FUE does not leave such a noticable scar (or any?). Which would enable me to shave my head completely at a later stage in life should I continue to loose more hair. I don't mind the option of shaving my head when I'm 30 something, but not now at 22. Because of my age it's difficult to be the "bald" guy in the group, I'm a confident person but hairloss has always been a sore spot, so I want to find out my options for now and at a later stage in life.
I have been researching for atleast a year and am not just going to wake up one morning make a call and have it done. It's a big decision and one that could haunt me for the rest of my life, or one that could change my life, so I want to be as educated about HT's as possible before making a decision. Not to mention it's not every day someone spends this kind of money.
