Retromercial Break - Hair Wiz

"When your sideburns get too bushy, just trim them with the 3-zero edge!"

Before the Flowbee had you cutting your hair by using your vacuum cleaner in the 80s, the Hair Wiz had your mom waving a razor blade at your head in the 70s. This minute and a half Hair Wiz commercial from 1974 does a good job of showing the product in use but you can't help but squirm at this small gadget being jabbed at a little kid's head.

Ladies, men, children - everyone gets their turn at the blades of the Hair Wiz. The original Hair Wiz came with a money back guarantee, two replacement blades, an instruction manual and a pocket-sized hairbrush for just $2.98.

More on the Hair Wiz:

There's not much information on the Web about the Hair Wiz. If you're feeling adventurous enough to try it yourself, you can pay five times the 1970's cost (or more) on Ebay but you won't get the free hairbrush.
