The Wig Affair sold me a beautiful synthetic Rene of Paris wig back in 2011, and styled it into a lovely shoulder length bob. There is a lady there called Anna (if I remember correctly) who is fantastic. She is a hairstylist so cuts the wig after one has been fitted and selected.
Back in 2011, the synthetic wig I bought was $460, and I received $369 back from the health fund. I believe the human hair wigs start at about $1,000. The synthetic wigs are easy to manage as far as washing and drying go. My wig would dry overnight and a bit of product and a brush and it was back in its style. Less labour intensive than human hair wigs I believe. There is not the constant washing and styling required. A synthetic wig can be worn 7-14 times before requiring a wash. They have been created to look natural in the scalp too. Being treated for bc doesn't leave a lot of time or energy to be constantly washing and styling. Much better to have something that can just go on and look great.
Always remember to makeup your face when wearing the wig, so it all looks right. Doing this does make you feel better too. Well, it did for me anyway. I had to sew my wig in a few places just to get the fit exactly right (I have a very small head) so that it didn't "slide" around my head. And bobby pins are great for extra "stay" too.
