If you're familiar with the Institute for Justice's high-profile cases (i.e., if you look at the back cover of Reason), you know about the silly and restrictive regulation that's been placed on hair braiding. The Chicago Reader's Tasneem Paghdiwala has the longest story you'll ever read (or need) on the subject, chock full of people who wouldn't call themselves libertarians complaining about government intrusion.
Of all the braiders I talked to, from 79th and Ashland to Wilson and Sheridan, not one was interested in learning how to shampoo, cut, or dye hair. "They think we don't do these things because we don't know how," said a woman from Togo, citing the chemicals used in full-service salons and her desire to stay far away from them. "It's because we don't want to do them. Why should I close my salon for one year, when I gotta feed my kids and send them to school, and pay $8,000, $9,000, to learn all these things I'm not gonna use?"
And so on.
