Will going over an unshaved area with laser promote hair growth?

I get laser hair removal done on my neck. There was only one patch that was prominent so i only shaved there but my technician goes over my whole neck. As all of it wasnt shaved, i didnt think any harm could be done. But then i noticed the hair that was light was getting darker abd now have to shave my whole ne k and get that done too. Plus, last session she went above my jaw line and now im seeing stubble come in even though i never shaved here. Is it possible she's trying to get me to keep coming back?
