Lately I've been working part-time on StyleSeat, the website for hair stylists and their clients. I've been helping with some Django development and am really excited about the product.
The basic idea is that as a stylist, personal trainer, massage therapist, esthetician etc. you can use StyleSeat as your personal homepage. You can list your services and prices as well as show off photos of your work. For Pro users, StyleSeat provides an appointment calendar and helps you keep in touch with your current clients while also generating new business.
For those of us who aren't stylists but are looking for a good haircut, StyleSeat has recently added an online booking feature (currently in beta). I'm pretty lazy and love the idea of finding and booking hair appointments online!
Up until now StyleSeat has been a bit stealthy... but now that the site is up and running smoothy they're open for business! Check it out: http://styleseat.com/
