Hello, I've become interested in the idea of learning how to trim my own hair. I like a neatly-trimmed look, but I do not want to spend $25 every two weeks getting a hair cut. Usually I keep my hair short, with a semi-awry look on top. Anyone have any tips for doing this? Any techniques to make it easier? By the way, I do have a trimming kit (electric trimmer, scissors, etc) at my house.
