German Classic with woman being shaved while drugged at dentist (or doctor?)

Note: the video I have included is _not_ the video I am looking for. I cannot find the video I am looking for, but it is a German feature classic where a woman (maybe Denise?) ends up going to a dentist (or doctor) and, while unconscious the dentist/doctor shaves her. She only realizes it after she has left the dentist/doctor.

That ends part 1 and there is a huge "To be Continued" that flashes up on the screen.

The dentist/doctor _may_ be Conny Dachs.
