What effect would an affordable baldness cure have on the world?

[Fixed by 35]

Just some questions I thought of today:

1) Will the person who cures baldness become a corporate demi-god of Bill Gates proportions?

2) Will men actually use a baldness cure in statistically significant numbers, or do most men just not care?

3) Will having hair be considered that important once everyone can have as much hair as they want?

4) Will there be enough barbers in the world to deal with the increased demand?

5) Will all the meathead poster boys for baldness suddenly get hair?

6) Will the world move closer to a meritocracy, as pretty boys can no longer rely upon their looks to get them promotions and plaudits in lieu of any talent (and conversely formerly bald talented men are no longer overlooked)?
