When I had a blunt bob haircut, I trimmed my own bangs. After that, I shaved my head completely and would just continue shaving my head in my sink with clippers whenever I wanted. This went on for about 3 years. Earlier this year I went to a GreatClips location for a proper haircut because I had a job interview, and they completely ruined it. Very very uneven and embarrassing. Now I am considering growing the bob back out but I am going to manage that awkward "inbetween" stage of hairstyles by trimming it by myself. If I don't like it, I'll just go back to a shaved head!
