To Prism99, you are most likely allergic to sulfates that are in the shampoos and conditioners. I am also, Get like a boil and busts and then is a sore that takes a while to go away, I used to have a lot on my head til I found out that I was allergic to it and started using some that doesn't have sulfates in it. The only thing I have found that I can use is the Loreal shampoos & conditioners that are sulfate free.
