OK Here is my 2 Cents
I am a 28 year old guy - with all of my hair intact. I have a very thick head of nice hair. So did my dad at my age...... but now.... he's balding - started in the back and worked it's way all around - but he still have a nice part - and my Dad would NEVER be the type to do anything like a comb over, or medication.
So - having the same hair type that my Dad does - I know baldness is in my future. I know I didn't get my Mom's family's hair type because they all start balding around 22-25 years old (my middle brother got that gene)
Anyway - I have decided that when it does happen I'll just take it with a grain of salt - and if I don't like how it looks - I'll just shave my head!
I saw a guy at WDW a few years ago that at some point tried plugs, but he must have lost a good deal of hair in the following years, because not only did he have the scars from plugs in the FRONT - but he also had the lines of scars in the back from where they TAKE the hair from.
If anyone has ever read the childrens book Hiram's Red Shirt - you know that taking a little from here - to put a little there, only works for so long.
Have him try the shaved look - and if he doesn't like that look go for the chrome! HAHA
Just my opinion and plan for the day my hair decides not to stick around! LOL
