Im going to wade in here, even tho im not exactly sure of the point of this discussion...
Based on my understanding of the question,which is "whats the diff, if any between a long hair wig of real hair and one of a more synthetic nature"...(that is it isnt it?)
I'd have to go out on a limb and say that if for any reason my wife had to lose her long locks (touch wood) i'd be most interested in getting together a wig of her hair for cosmetic (and other) use after the fact.
But a wig of another's hair, or synthetic, wouldnt do it for me, other than cosmetically, or i don't suppose her for that matter.
Whats the diff between real long hair and a wig of real hair? Bout the same as comparing a porsche and a plymouth i suppose, and the diff between a real hair wig and synthetic is that difference again...
All that being said, let's leave the real hair where it belongs, on real heads, dragged lovingly across real chests, real often...
....damn there i go lettin my dick do the talkin again....
Now, for the hell of it, some links...
