I&#x27;ve looked into it because its been a traditional straw dog for decades.<p>The stereotypical image of an all male barber shop giving men buzz cuts with a clipper is appealingly boring, but the work clusters inseparably with womens beautician type work, and that work can be crazy.<p>They use corrosive dyes and peroxides and bleaches that will damage your skin or destroy your eyes both as a victim or as an employee.  Used correctly its safe as a surgery scalpel.<p>They insist on mixing technologies that are very problematic for the general untrained public to mix, like water and electricity, as either victim or employee.<p>There can be disease issues, not quite of the level of a biohazard lab, but you want at least some minimal standards and of course some of the chemicals used for sterilization are not necessarily safe for the general public to screw around with as either victim or employee.<p>This was a &quot;local news issue&quot; a couple years ago where the big bad state was attacking &quot;retired beauticians cutting hair in their basement part time&quot; but they carefully don&#x27;t mention its more than cutting hair, there are open containers of high strength hydrogen peroxide in a residential house with kids in it, or the hair dryer not plugged into a GFCI outlet next to the running water sink, etc.<p>WRT danger and risk its about one or two steps beneath the truck driver with a CDL and hazmat cert, or the electrician who does the wiring for a public pool, or the welder at the local nuclear plant... and the hoops to jump thru are also, appropriately, about one or two steps lower.  From a high risk down view as opposed to low risk looking up, its not unreasonable.<p>If you propose separation of the harmless hair cutting stuff from dangerous stuff, then the tear jerking starts about problems of scale and unless there is a level playing field of identical training only giant salons will be able to afford the specialized and soon to be rare training to color hair or whatever.<p>It makes a great straw dog, but is a pretty good match compared to other fields.
