>>513925788 (OP)My dad was a complete cheapskate, and used to shave with only soap (regular handwash soap)
So I had to learn WHY all on my own.
You use shaving foam for:
Marking the areas you havent shaved yet
Collecting the shaved hair, and preventing it from sticking to your skin.
Softening the hair, and moisturizing and lubricating your skin.
Some brands help reduce bleeding.
You use aftershave cologne for:
Numbing the skin, kinda like painkillers.
Treating nicks and cuts, and reducing chances of infection.
And it smells nice.
