I've only had one wig, for one month and it's synthetic.
It seems to fit the bill. Are human hair wigs a lot better?
I love the look and feel of the natural hair. Plus, you get to style them, that's the one thing that drove me nuts about the sythetic. Be ready though...the good ones don't come too cheap. I wish I wouldl have got one when I started but the synthetic did look really good at the time.
