Washing a Synthetic Before First Wear?

I just bought my first synthetic lf. Bree by Sensationnel. It just came in the mail and now I don't know what to do. Should I wash it before I wear it? Or will washing it cut it's life expectancy?

I had to do this with my Bentley wig. I'm not sure if its cause I got her in a color but when she came she was dry as hell when I brushed the curls the hair frizzed and poofed and lost all definition. The curls were stiff and dry. So I put it on top of my manaquin head and washed in shower with conditioner only and let it sit in shower all night and drip dry. Now the hair is super soft and smells great and when I finger combed the cults hey turned into the tight waves/curls they were originally supposed to be.

Thru trial and error for ME... I don't wash my wigs first.  To me, especially the syn cheaper wigs I'd say no miss.  The cheaper wigs to me... they  just don't bounce back after washing, they tend to look older faster.
