no shampoo commercials
There would be no need for hair spray. - Hooray! I hate the smell of hair spray.
I'm already bald. Welcome to my world...world!
There would be lots of hat shops around.
Not that much different. The people who look good with a bald head would get all the praises and attention. While ugly bald headed people would be the worker bees.
Stocks in hats would go up.
