Thanks for this. It's some really good insight for me. I've had a few ideas bouncing around in my head for SaaS products to serve a few different small business niches where the existing software sucks badly. I think all of those markets would have similar difficulties to the ones you found in salons. On the one hand, it's really frustrating to know that I can build a product which would make peoples' lives and businesses better, but that I'm unlikely to be able to make it financially viable. But on the other hand, I'm grateful to realize this before pouring months or years of my life into it.
