My friend is a hair dresser and her hair clipper's electrical plug is coming
loose in the wall outlet.

The outlet is about 4 feet off the ground, so the clipper's cord comes out
of the outlet, drops down a few feet and then go up to the clipper without
touching the floor. IOW, it forms an U shape and the constant movement of
the clipper and the weight of the cord eventually loosen the plug.

It would be easy to attach the cord to the wall a few inches away from the
wall outlet, so that movements of the clipper would not reach the plug.
However, she needs to be able to unplug the clipper and move it to another
station/chair easily.

I temporarily bend the prongs on the plug to make it stay more firmly in the
outlet, but this is only a temporary solution. What's a good long term
solution?

Since she moves from station to station, you have a built in
troubleshooting process:

Does the plug fall out of every receptacle that she uses?

If Yes: The plug is worn. Replace the clipper's plug a quality plug.
If No: The receptacle is worn. Replace the receptacle with a quality
receptacle.
