How Disgusting Are The Licensing Laws?
Melissa Quinn writes at The Daily Signal that it takes 300 hours and a bunch of money to become a shampooer in Tennessee:

In Tennessee, not only do natural hair braiders need to attain a license, but those shampooing hair in their shops--known officially as shampoo technicians--do, too.

The Tennessee Board of Cosmetology and Barber Examiners defines a shampoo technician as a "person who brushes, combs, shampoos, rinses and conditions upon the hair and scalp," and the state began requiring shampoo technicians to attain a license in 1996.

To get a license, aspiring technicians must pay a $140 fee to the state, complete at least 300 hours of education in a course on the "practice and theory" of shampooing, and must be at least 16 years old.

A 2015 catalog of coursework from the Franklin Academy lists tuition for the shampoo tech program at $2,700, which doesn't include the $400 required book and kit, or the $100 in application and registration fees. The Franklin Academy is a nonprofit institution based in Cleveland, Tenn., that trains those seeking licenses in cosmetology.

"The curriculum is burdensome, expensive, and totally irrelevant to what they want to do," Boucek said. "The fact they'll specify what kit you must buy and that you have to go to school shows they're concerned about making the individuals spend money that benefits the schools and limits competition, which is what you would expect from a statutory regime that is designed to benefit existing market participants."

Loved this guy's remark from the comments section over there:

300 Hours? That's because the instructions on the bottle say "Lather; Rinse; Repeat." They don't say when to stop.

And check out this steaming wheelbarrow, also from the comments on the Daily Sig piece:

The Hair Experience
Actually, lice and their eggs ARE very hard to see. As a salon owner in Tennessee, 300 hours is not too much to ask for someone to get for a shampoo license. People who do not know about the hair industry think it's easy and for dumb people who can't find a real job. It's not, actually. I have a master's degree in law. And I'm a proud hairdresser and owner. There are MANY scalp conditions and diseases that can spread like wildfire among families if somebody doesn't know what they're doing behind the chair. I had to get 1500 hours of cosmetology education, which took about 10 months. So why would someone complain about getting only 300?

As a salon owner in Tennessee, this person has a vested interest in keeping out the competition.

How about I get the choice as to whether I get shampooed by somebody unlicensed -- and whether I get to eat unpasteurized cheese on the way there? Too much government, too much crony capitalism.
