Like everyone else has mention, the helmet should be replaced after every fall, what we was taught her 4h. With that said I don't replace mine that often. I'm looking at replacing mine in the future, but haven't decided on it yet, I really should even know it's not even a year old. There is no outside damage done, but I know most likely inside damage was done. I got an concussion but didn't physical hit my head that I remember, it took 2 days for the effects of an concussion to even appear. I realize the risk I take when I don't replace it, but it's better than none.
