Hi, I have small red bumps along my hairline and on my forehead. Bumps were originally just felt under my skin but are now visible, bigger, and red. I have a small cluster of bumps right below my hairline on my forehead. Bumps usually do not form a white head like pimples. Tried using Demorex shampoo but that didn't help. Earliest appointment I got at dermatologist office in March 2014. Any ideas on what this can be? If so, what can I use to treat it? I ride horses so am always wearing a helmet, but I'm 23 and never had this issue (or any other type of face issue) until now.
