You cannot import a haircut. It’s a service provided to you where you physically are by people who live close by.

You can technically automate hair cuts (badly, but it is technically possible, most wouldn’t want to pay for it yet).

You can buy an electric hair trimmers and give yourself a standard length.

But there are no robots for remote-controlled hair cutting. Until there are, you can’t import them.

This is why haircuts are expensive even outside of the USA, and why they vary in rough accordance with the local cost of living.
