ok fbdedicate... Im assuming that you shave straight backward with the headblade, which is not what your need to do. What you need to do is, leave your head alone for a little while to give the razor bumps time to dissipate. After you do that, I suggest that you quit using the headblade for a little while until you know what your doing. Since Im also succeptable to razor bumps I can tell you that what you need to do is shave your head with the grain. That would be forward for the front of your head, backward for the back and straight down for the sides of your head... do not, I repeat do not shave your head against the grain. Once you get a good shave this way if you want your head slicker than you can go over it sideways across the grain. However never shave against the grain if your prone to razor bumps.
