When you see a person with bobby pins in their hair, they’re usually wavy side up. This is because they probably assume the curves in the pin are there for fashion. The true purpose for the little waves, however, is to grip the pin into place by catching it to the underlying bulk of hair. In other words, wavy side down.
It's correct though, I can remember all the publicity when they were first introduced.
So if I try to save your life, but you see that it will make you uncomfortable, can I assume you will pass on the help?
Yes, had me totally confused .
