Most of your clients probably juggle quite a bit of stress on a day-to-day basis.  A great way to alleviate them of this as well as elevate your service is to offer a little massage after the service. Keep in mind this does not have to be anything fancy, just a minute or two that will give your client an extra kick of rejuvenation. This above and beyond service will surely earn you some positive reviews, repeat clients and new clients.
