Pin ups
I think I gave up using bobby pins when I was about 15. They either fell out immediately, or I found them the morning after and spent an hour trying to untangle them from my bangs. Well, I know I’m not the only one, and it seems that we’ve been using them wrong all of this time.
The double-sided design of the bobby pin is intentional, and the wavy section should be turned toward your scalp. This means that the waves grab onto your flowing locks and hold the pin securely. Perhaps I should give them another go next time I consider an up-do.
