In the Orthodox Jewish world, many women wear sheitels, essentially wigs sourced from human hair.
The entire buying experience is very different from what Ben describes in his blog. The women who sell the sheitels provide the whole experience, from picking out the hair type/color/length, etc, to making sure it fits well and that the customer is satisfied. Granted this is a much smaller and niche market, and the products (sheitels) themselves can easily sell for $1,000-$2,000+.
