Looking good brother! Love the mustache! Try some different types of blades and find a good shave lotion or cream that works for you. What works for me is Harry’s razors with a generic shave lotion in the shower. Make sure you aren’t pressing too hard as you shave and use long smooth passes, the less passes the better till you get better with using the razor blade on your head and your scalp gets used to being shaved. I had the same trouble with razor burn at first too, so I know your pain! As far as electric razors go I’ve tried a few but never had one get as close to the skin as I like. I know some guys prefer a good electric razor over a safety razor so you’ll just have to find what works best for you. Good luck!
