Sweaty bangs morphing into what looks like piano keys. Greasy and separated these piano bangs can be due to sweat and/or oil. Instead of being able to rock your bangs straight across your forehead for that perfect bang look, you now can play Beethoven's 5th on the piano key's perfectly placed up your forehead or even better your fivehead.
I'd love to see some pictures of ladies with long hair who have bangs, not piano bangs sitting on top of foreheads.
