I have been to plenty of Sally's around town. This location is pretty legitimate. I would not say it is the best one in town, but it is the closest one to me. The staff gets a 6/10.
The one bad experience that I did have here was when I was looking to buy a cuticle nipper. I saw the one I wanted online, but couldn't find it in store. When I asked the male employee to assist me in finding it, he said they had two kinds and began to show me the first one. When I brought up that the one I saw online was cheaper, he immediately said that they didn't have it and didn't even bother to show me the second nipper he mentioned. Rude...
Nonetheless. Sally Beauty is a good company. Don't forget to get a Sally Beauty membership card and to sign up on the website; it is totally worth it.
