Please check out my article, "Headed in the right direction: the head covering as marker of a Jewish woman’s identity Part II," which you can find at http://www.examiner.com/x-12088-Brooklyn-Jewish-Examiner. Here's an excerpt:

"Wigs used to be monochromatic, badly fitting, and made of synthetic materials that gave them a stiff, unnatural appearance. Only in the last 30 years or so wigs have wigs become almost more beautiful then some women’s own hair. This is because they are now available in a variety of human hair textures...and a full spectrum of shades."

Read the whole article and be sure to click on the "All About Wigs" resources section on the right-hand bar of the page. My article also contains useful information on how to control cost and get the most out of your wig. Please feel free to ask me any further questions either here or on my page at http://www.examiner.com/x-12088-Brooklyn-Jewish-Examiner.

Hope to hear from you soon!
