It doesn't surprise me that women who might make $2 to $5 a day would be willing to sell their hair for $100. That's one or more months' salary! American women might charge $500-1000 or more, as some do, but they make much more. And that $100 may represent their only chance to save money.

So basically, if you want to exploit someone in a lower salary bracket (or country), you won't find them hard to find, and they might even thank you for it.
