Sally is not the best of beauty supply stores but its far from the worst. I think they have a great selection of reasonably priced hot tools. They have really great buy on get one sales so you can really clean up from here at times.
This is not my spot for hair extensions, nail supplies or shampoos because I find I can get what I prefer other places for better prices. But they have good prices on wraps ties and Bobbie pins for styling. I also go here to get Aphogee products because it is the only place I can find them. Aphogee is a really good product if you need to strengthen you hair but make sure to read and follow the directions carefully.
Associate are usually nice and greet me when I come in so I would say service is okay here.
