As someone who has shaved their head and not paid a barber for 20 years, not a penny.

Another one that wants to scan my face...... You couldn't pay me to scan my face. You would have to force it like governments do. Go to a barber shop

I started cutting my own hair decades ago, and tapering is probably the first and easiest thing I learned. Blending different lengths on longer hair is much more of a challenge IME. That and specialised styles I guess, which I never really bothered with.

a what

TBF I'd rather pay a person to do it.

... You know a haircut costs 1.5 cheeseburgers (ish) right? I'll take a human who isn't going to hallucinate and randomly remove my face thanks.

I'm probably just going to go back to shaving my head. I have no trouble growing hair, but can't really be bothered. My wife doesn't care either way which is probably the thing I most care about

If it did a good reliable job, 200€-400€ I'd rather just go to the bathroom, put something on, and wait for a short while, and then have a good haircut. Going to a barber and planning etc is a lot more work

If no face scanning, and it was quick/convenient maybe £5 otherwise I'll stick to humans

Nothing

I'm bald on top anyway I'm just going to keep shaving for free

Zero dollars.

Now if it could give me a perfect shave around my downstairs bits, then I'd be willing to shell out $200 or $300.
