How do you know if your scissors need to be sharpened?
Did you recently drop them and they just don't cut the same or "feel" right?
Do the tips not close completely or cross over?
Do the blades feel loose?
When you cut, is the hair "pushed" down the blade first?
Does hair "bend" in the blade?
Are you considering buying a new pair of scissors?
