Hey Doug and welcome! Just do it buddy, shave that dome. And heck, if you don't like what you see (which I doubt) you can always grow back what you had. I've been shaving my head for about 10 years. I, too, was very reluctant at first. But once I did it, I couldn't understand why I didn't do it sooner. It's very liberating and it actually makes you feel in control of yourself, very empowering.
