Ha! I think a lot of people of this forum need to watch this:

I'm not trying to be a jerk but even Patrick Stewart had problems with hair loss. Sure, he has played awesome roles now and has lots of $$$ but he had to overcome hair loss first, and the worst part is that the majority of us will never be as fortunate as he is.
So, besides that guy and Jason Statham or Vin Diesel (both with decent facial expressions, enviable body and tons of money), please name one hero/icon/character that is bald and women would desire as much as say Robert Downey Jr.? Correct answer, you can't.
Hollywood distorts the way public perceive the loss of hair. Take a look at Tony Soprano, Voldemort, Walter White, Dr. Evil, etc. A bald character is secondary or just the bad guy, never a charming heroic figure.
