Allergic To Wig

I just finished 3 months of chemo last month, lost all of my hair in the process and was wearing scarves most of the time during chemo and even afterwards.  Recently I purchased a synthetic wig from a reputable wig salon in my area.  I wore the wig out of the store and it seemed to feel good for ahiele until after two hours I started to break out in rashes all over my face and neck, wherever the hair touched my skin a rash would break out, my eyes began to get red and sore as well and I felt like I was going to pass out.  Could not wait to get home to take the wig off.  I heard that washing the wig in viengar and then shampooing it would help, from what I heard is that I could be allergic to the Alkaline they use in processing the wig.  I did as instructed and I still broke out in a rash.  Is it possible that I am allergic to synthetic fibers?  If so, how much would a human hair wig cost and I am beginning to wonder if I mgiht have the same problem.  There is one website that I found that sells human hair wigs ranging from a hundred dollars and on up.  It is called ewigs.com.   Does this price sound reasonable or am I going to get a cheaply made wig?  I really miss my own hair and do not really want to have to wear scarves and hats for the next several years before my own hair gets to the lenght I use to have it, ti was below shoulder length.  Thanks for listening.
