Suggest Treatment For Irritation On The Scalp

12/2/16 I went to the hairdressers and had my usual hair color dye done. Next morning, I had an irritation on scalp and scratched off a scab that was not flat, somewhat lifted. Sunday morning after a hair wash I noticed red area about the size of two eggs, oval shaped. After a few days it was getting better and was the size of a nickel. The irritation today did get bigger, more patchy, skin came off in thick amounts inched washed and after applied tea tree oil. A couple of reder areas are what looks like hair follicle. The irritation is somewhat painful, just a little bit of itching.
