Abandoned the bonding idea for now and am working on embracing more changeable and less costly options. Found a nice homey wig boutique in Richmond and purchased two brunette Raquel Welch's there. In front of people I see all the time but am not super close with (which is most people ;-)) I am still clinging for dear life to the self-made helper hair I've been using for four years... which is familiar but pretty crappy right now since I've got next to no hair, particularly at the front, to even "help". But in the evenings I've been "practicing" with my starter wigs, learning to manage their quirks and challenges and make them look as natural (or at least as flattering) as possible. Have wigged out solo at restaurants a couple times and learned that while I still feel very much that something with its own presence is sitting atop my head, it really doesn't look that way from the outside, at least not to untrained eyes. It's an interesting experience.
Still holding out hope that I'll find a synthetic wig to be my everyday Me wig, that I put on and feel giddy about. But that will have to be a combo of brown-black (shade 1B), lower density (prolly 100-110%), and spiral-curly (type 3B?) that looks neither too Afro nor too WASP-who-used-rollers. Going more for Greek goddess curls here :-D Is that just a pipe dream? Le sigh.
