Can you get split ends from washing your hair every day?

Yes and also blow-drying it and also the environment (sun, smog) can cause this. There are good products out on the market to make your hair healthier. I use "Frizz-Ease" to stop those frizzies and it works great! Hot oil treatments on your hair is also good and should be done a couple of times a week to keep your hair in shape. Also, get at least 1/4 - 1/2" cut off your hair to help get rid of those split-ends.
