Why not just make a "Stop growing hair" product ?
I remember the time when there were razors with just one flat blade. The problem was that you had to change blades pretty often. Then came the two blade disposable ones and then the three blade ones.
That was when I stopped following the number of blades and just went with something that I liked.
As I was sifting thro the news, I read Gillette has come up with a 5 blade razor. Why not just make a "Stop growing hair" product ? Wouldn't that be simpler ?
