Hey guys, about 2 weeks ago I started buzzing my head with no guard. Then on Sunday i shaved it with a razor, and it was a great shave, really smooth and all. Then i went to do it yesterday, and no matter how much i shaved it, it was still stubbly, and my skin was getting very irritated (bumps, redness, nicks). Is this cuz of a dull blade? I just started using that razor on Sunday? They are disposable razors, but they do have 3 blades on them. I also use a shaving lotion, not a foam like everyone says not to use. And i also took a hot shower before hand. So if anyone could help me out with this, it would be greatly appreciated. Thank you!
