IDK if this is a salon issue, but another major issue is so many subscription businesses have made it damn near impossible to end your subscription without sitting in a queue for an hour and having their retention specialist give you 900 offers to stay.
That alone has made me much MUCH more leery to subscribe to anything if it's not something that can easily be canceled (For example, using Google play to subscribe to things since they make it easy to unsubscribe).
The New York Times was most notorious for this.
privacy.com lets you generate credit cards for every vendor so they don't get to take money from you unless you actually allow them to.
