What is the business case for the general electorate in requiring hairdressers to be licensed?

Question

In the United States (and in many other countries!), there are several professions in which it is illegal to practice without a license. While most states typically handle these schemes, even Congress was afforded the power in Article I, Section 8, under the Commerce Clause, making such schemes even potentially federal.

For obvious reasons, you want quality control in regards to your doctors and lawyers. I can sort of even see the justification for funeral homes - having needed to use two in the last six months, no matter how prepared you are, you are using them in a time of acute need, and there is a case to be made that you want regulation to ensure you are not taken advantage of.

And, most professions have a vested interest in restricting the pool of potential purveyors, in order to bid up prices for the remainder. Indeed, lawyers in particular have sought to "raise the bar" in order to deal with a glut. And again, doctors are paid more when there are fewer of them. But for any one industry with an incentive to restrict professional practice, there is typically a wider electorate that presumably doesn't have the incentive to see prices rise. And, in a democratic system, one would assume that cartel power would, in the long run, be voted out. After all, self-interest amongst consumers (and their sheer numbers) should serve as a check.

But here again, there seems an obvious anomoly. A barber or a haridresser is a licensed profession in many states and countries. The work is not particularly skilled (one can earn a degree in less than a year), nor is the industry particularly prone to horrendous side effect in the event of a bad apple. (Any hairstyle by Lady Gaga, Cher, or Hillary Clinton notwithstanding.)

Why then, do these licensures remain? What is the incentive for the average person to support an artificial monopoly amongst an otherwise low skilled profession? Why not require janitors and sanitation engineers to be equally licensed?

Answer 1

Since comments are being deleted, I'll try and create an answer. However, the actual question:

What is the incentive for the average person to support an artificial monopoly amongst an otherwise low skilled profession?

Is a leading question. It's assuming that the the primary purpose of licensure is to create an artificial monopoly. It's also assuming that licensure is only useful for high skilled professions. I don't see either as being necessarily true.

In general, however, licensure is a way to finance a regulatory and inspection system. Typically this is done in the name of public health and safety. Hairdressers do more than cut hair...they also apply potentially dangerous chemicals, shave faces, physically touch numerous people on a daily basis (potential for spread of communicable ailments such as lice) etc. So I think there's a case for a public safety argument.

Why not require janitors and sanitation engineers to be equally licensed?

I could see a public safety argument for custodial work, but that would be a much harder one to make, given they are in less direct contact with the public. As for sanitation workers, same thing, though it's important to point out the sanitation industry is heavily regulated as a whole, again in the name of public safety.

EDIT:

Per DVK's suggestion, I did a quick search to find some supporting data to back up the statement that licensing is a way to fund the actual department handling the inspections. Alas, most .gov sites are pretty bad, but Colorado's is decent and here's info on their funding:

The Department of Regulatory Agencies (DORA) is primarily cash funded by regulated entities through fees and assessments flowing to cash funds, and DORA is relatively unique among state agencies with regard to the volume, complexity, and autonomy with which it sets industry fees based on appropriations made by the General Assembly

source: http://www.colorado.gov/cs/Satellite?c=Page&childpagename=DORA%2FDORALayout&cid=1251627011148&p=1251627011148&pagename=CBONWrapper

As for purpose of the agency, Colorado's licensing department has this as their mission statement:

DORA is dedicated to preserving the integrity of the marketplace and is committed to promoting a fair and competitive business enivronment to Colorado. Consumer protection is our mission.

source: http://www.colorado.gov/cs/Satellite/DORA/CBON/DORA/1249686120221

So not explicitly 'for the public health' but consumer protection. Interestingly, counter to the original question's assumption, they explicitly state additional objectives that one would argue seem to be specifically promoting commerce (rather than creating an industry monopoly).

Other states seem to take the 'public health' route with their mission statement. From Kentucky:

The Kentucky State Board of Hairdressers & Cosmetologists was created to protect the health and safety of the general public, to protect the public against misrepresentation, deceit, or fraud in the practice or teaching of beauty culture, to set standards for the operation of the schools and salons, and to protect the students under the provisions of this chapters.

Answer 2

"For obvious reasons, you want quality control in regards to your doctors and lawyers."

Once you admit that the state is the means to exercise this control, you admit the validity of the same argument for hairdressers. Bad haircut is, well, bad, so what's wrong with wanting quality control? Maybe for you hairdressing means little, but for somebody bad haircut could change their whole life (e.g. job interview or date gone wrong, bad consequences ensue). As long as you accept the state has to exercise quality control, why hairdressers be exempt? It may be a low priority for you, but put that to a vote and see if it's equally low priority for everybody. If they vote for quality control - then they think quality control needs to be there.

Why not require janitors and sanitation engineers to be equally licensed?

The same applies to janitors, it is only a question of having the right lobby and the right public campaign. If in a particular jurisdiction janitors form a union and conduct successful campaign to require licensing - there's absolutely no reason (provided you accepted the initial premises) why janitors won't be licensed.
