Vegan, sulfate-free shampoos. A big emphasis on recycling. And an emphasis on holistic wellness. Those are among the ways in which Spaville Hair Studio in Stephenville, Texas, has focused on green practices. Since the salon opened last fall, said Amy Lusty, one of the owners, the operation has aimed to do more than provide hair services. "We like it to be a spa experience. I think we try to provide a relaxing environment -- for ourselves as well as everyone else," she said.
