I will say that most people who come in with such an issue need a new cable and housing. There will be a kink, or rust, or etc. if it’s straight just dripping the heavy oil down the housing can help, but I usually start fresh.
The other common step issue is the seal head being dry. If it’s a reasonable person I pack it full of Slickoleum and just tell them to wipe away whatever excess purges over the first 1-2 rides. If there’s a barrier to that level of teamwork (wiping the excess lube) then I’m much less aggressive with the grease.
If both those things don’t fix it then go to carbon paste in the seat tube and as little clamping force as possible. To keep from twisting/slipping.
Finally, not all seat collars are created equally. A taller, thicker one with better tolerances tends to better load the seat tube. Not a guaranteed fix but if you have some dainty clamp that could do it.
