I'm not bald, but, as a couple of gals here can attest, I am not well crowned.
Even HRT hasn't helped much for me in that realm, and I wear wigs pretty much *constantly*.
I wash them weekly, never, ever, ever use tapes or glues, and I sleep in a couple of short hair ones.
Lacefronts are awesome.
I will say that my approach to wigs is one of *enjoying* them, as opposed to feeling like they are my only option.
I don't know enough about them to really give you much in the way of advice, but I have, at present, about 9 of various colors and lengths, and I am known to even swim in the shorter ones.
Wearing one to bed will, ultimately, destroy it. I do not like human hair wigs -- the maintenance on them is horrific, and the lifespan is about a tenth of others.
Kanekalon fibers are pricey, but they tend to be something I actually look for.
THe most important thing, though, is find someone who understands the concept of cut, or get a very expensive, long hair wig and have it actually styled to your face.
I've had, in the last year, well over 40 wigs. My circumstances are such that I could, but they have ranged in price from 30 bucks to 210, and the price never matched the quality.
Not much help, I realize, and I'm sorry I'm not more, but that one woman? Sounds like she is trying to work you.
Just order some online (wigsalon.com is cheap, and
http://www.wilshirewigs.com isn't bad, and I've used
http://www.paulayoung.com on occasion, too) or hit up the tiny shops that carry them as a sideline, if you have such locally.
