Bad quality hair

I bought my 22inch full lace about 5 months ago and recently started to notice its not full on human hair, there is some other kind or Peruvian in between and one can clearly notice the difference. Sometimes when I wet my hair I see how some look and feel different. It is also shedding alot. I have been using wigs for a few years due to my chemotherapy I can not grow my own anymore. Uwins is a *******, very expensive for not so good quality after a few months! I am very disappointed
