Barber: You hold a sharp object to somebody's head wrong, you could take out a chunk of scalp. If you're malicious, you could do more.
Electricians: You do it wrong, you can literally fuse your corpse to the thing you were working on.
All of these are greater consequences than having prod going down. In these fields, things can go very wrong very fast, and all these professions are right to same some form of certification.
Barber: you don't need a two year degree to learn how to use scissors on someone's hair without cutting into their scalp. This is something anyone with basic motor skills can do. And if you're malicious, you can just as easily run out into the street with scissors and start stabbing people. You don't need to get a job as a barber to give yourself that opportunity.

Licensing is not the same as certification. Licensing means you are forbidden from doing something until you meet certain conditions. In any occupation where the parties subjected to risk are consenting to that risk, there's no possible justification for such a restriction that doesn't involve a paternalistic argument that people should have their liberty curtailed by the state for their own good.
