I have really been enjoying having a nice smooth head. That is, until the back of my head decided to flair up. I'm gonna have to keep it to just WTG on the back of my head and not do the ATG pass. I love the smooth feeling, but these ingrown hairs and bumps are not gonna be fun. Sucks, it's the only part of my head that had a problem. The picture shows the bumps, but doesn't quite capture how bad it is.
