I go to the Sallys on Scottsdale road and in Mesa often and have never really had any complaints.
When I came to this location I was with my mother looking for a product to tame my younger brothers wild jewfro. The other Sallys stores suggested multiple products and none of them worked. We were getting kind of desperate and now our bathroom is full of "ethnic-grade" taming product meant for african american hair that didn't work.
The salesgirl here was very helpful and gave us a product that she said worked on her boyfriends jewfro. She explained to us why the african products we bought werent working and then told us that if for any reason the one she suggested didn't work we could bring it back. The other Sallys stores have always told us that there is a no return policy on opened product. We were so thankful!
The best part was that the product DID actually work on his hair!
The store is the same size and carries the same products as any other Sallys but I'll forever hold this one dear in my heart for the return policy and helpfulness of the salespeople.
