Double checking your work is the main step you need to take to make sure that the cut looks like it was done by the hands of a professional. Grab sections of hair from each side of your head that fall in the same area, and slide your fingers down to make sure that the sides match. If one side is a little longer than the other, feel free to return to step one or five depending on the layer that is mismatching.

And with that, you've just saved anywhere from $30 to $100 on a trim by learning how to cut your hair at home.
