People, people, people and more people. Looking happy. And pampered. And probably smiling.

At least one of your daughter smiling and looking friendly and approachable.

These are nice abstract interior shots, but they're too abstract to sell a personal experience.

Suggestions:

I'd cut out some of the abstract shapes so you don't see the whole salon, and collage them into an abstract composition. Add a logo or other page furniture with some curves, and write some copy about how fantastic the experience is, and how many different options there are, how special some of the options are, how experienced your daughter is, maybe a testimonial, etc, etc.

Adding an online booking system could be useful too, so people don't need to call her while she's working.

You could keep the cool slightly abstract look, but I think it has to be personalised.

For example, I can't tell from these whether the clients are expected to be young and modern, with spandex tops and belly-button piercings, or goths with vintage undergarments-worn-as-overgarments, or polite elderly ladies with blue hair, or businessmen...

One might also think about whether the purpose is to actually show the environment of the shop, including, for example, the legs of the chairs, or if it is more of an atmosphere sort of thing that would be effective advertising, where you might crop the pictures (by zooming in, perhaps) much more aggressively. There's always this desire to "get everything in" which sells lots of wide angle lenses, but if you look in magazine adverts, usually you can only see a nose and an eye or a leg and a shoe or something--really close up.

People like to dress up and get their pictures taken; perhaps a grand opening party could be arranged and suitable photos taken as part of the run-up...
