I'm sure that there's some theoretical route to do it, but I'd be really hesitant about trying to induce situations where one's immune system attacks one's own cells. That can do some pretty unpleasant things.

Do not try doing whatever you're planning on doing to yourself

Interesting questions. It would also remove eyebrows and eyelashes, which serve to protect eyes from dust and things like that. Armpit and pubic hair serve to reduce friction in those areas and prevent chafing. Nostril hair, assuming it would also be gone, is part of the filtering system of the air we breathe. Considering all those health implications, being fully informed before doing it would be really important.

But if someone still wants to do that to themselves, and is an adult capable of making their own decisions, I say let them!

Whether it's possible or not (the core of your question), I have no idea but the other comments seem to have some theories about that.

don't do it, dude...

Sounds doable. You need a hair follicle cell culture and to give it a reason to attack it like a vaccine works. Inverse vaccines are a thing now, should not be too hard to do.

But honestly, I would rather you get some mental health help.

Given the knowledge base in inducing hair growth, I would think that developing a treatment like you're describing would be in the realm of possibility.

That being said, a medical treatment to loose all hair likely wouldn't sell given the human aesthetic preference for a head of hair seeming to be almost hard coded in humanity as a sign of virility.

The tech is likely there, but the demand isn't.

Have you heard about chemo? It's really nice! 👍

Wouldn't you seriously fuck up your balance and hearng since part of the inner ear relies on hair in a complex system? This seems like a bad idea.

Nair?

Had too much of this? Perfume
