I've tried just about everything - need advice from experts

Hello -
My house is about 50 years old...I've lived here about 10 years.
Throughout my time living here, I have experienced "slow draining"
in the bathroom sinks, and showers. The toilets are never an issue.

Over months / years, I have used all of the plunging techniques that I have been able to find on youtube, and it usually helps the problem temporarily, then it slowly gets worse again. I've removed / cleaned traps in the bathroom sinks multiple times and snaked and snaked and snaked. As far as I can see, clogs (at least clogs in the obvious places) are not the issue.

Over the past few days it has gotten much worse and the bathroom sinks drain ETREMELY slowly. (taking hours to drain).

Any thoughts?!?!
Thank you!

I've said this before but it is worth mentioning once again. I don't like to hire anyone at my house to fix anything, but sometimes the headache these problems cause are not worth the stress and I will opt for a professional to clean the main line and drains correctly. They usually also guarantee their work for quite some time, so that is one less problem to deal with down the road.
