Since I've started using ClearHead, I notice that, on some shaves more than others, I get redness on my head that will go away after 10-15 minutes or so under a fan. No razor bumps, just this post-aftershave redness. I get it worse on some days more than others. I never used to get this redness, I don't think, when I would use Nivea Extreme Comfort Post Shave Balm. That also didn't have a stinging sensation, like the ClearHead does (some days worse than others). I'm pretty sure on these "worse" days, the worse stinging coincides with the worse redness. I keep using ClearHead though because I don't get any bumps or dots or anything, so I put up with the momentary pain/redness.
