Hairdresser AI

The Hairdresser AI demo salon: a dark barbershop, a barber mid-cut, and the headline "Entra sabiendo", which means walk in knowing.

One question started it: how far can a single person take a real product when the tools write the code? Hairdresser AI is the running answer. I designed it, built it and shipped it end to end with Claude Code and Codex: product, interface, backend, the lot.

The idea is simple and a little personal. Walking into a salon means trusting a stranger with your hair, so the product shows you the cut before the scissors come out. Upload a photo, pick a style, see yourself wearing it, then book the chair.

It works end to end, and what stopped it was never the code.

The real next step was always selling: walking into salons across Barcelona and handing them a site that shows their customers the cut before they commit. Roughly 70% of hairdressers here still have no website of their own, so that is a good business. It is also a full-time one, and between cargo drones and everything else I can’t give it the hours it deserves.

So it sits here, built and waiting. If it moves, this page gets a sequel.
