I think, more specifically, they thrive on high repetition rate, high platform retention, and high commoditization (or, equivalently, low provider retention.)

Hair cutting/styling, AFAICT, has fairly low repetition rate for most users, and low commoditization / high provider retention (and that's even more true among the segment of the population which does have a high repetition rate), and so the utility of the market platform seems pretty low for most users and providers.
