Do enzyme cleaners help a slow bathroom drain?
For a bathroom sink that is starting to drain slowly, how would you decide whether a drain-maintenance product is appropriate or the restriction needs mechanical investigation?
Enzyme or bacteria-based products, chemical clog removers, and the familiar baking-soda-and-vinegar mixture should not be treated as interchangeable. The useful question is what the actual product is intended to do and whether it is compatible with that fixture and plumbing. For example, Drano’s product FAQ and Dual-Force Foamer instructions describe that manufacturer’s products; they are not general instructions for every drain cleaner.
Does the slowdown affect only this sink, or are other fixtures backing up too? I’d establish that before choosing a treatment rather than rely on a regular cleaning routine to explain away a worsening problem.

I would not use the description 'natural' as a safety test around children or pets. Keep any cleaning product secured and follow its actual label. If another cleaner has already been added, do not add vinegar or a different product on top of it; tell the plumber exactly what was used before anyone works on the drain.
For a stubborn clog, I wouldn’t count on either one to clear it. Baking soda and vinegar fizz, but that reaction isn’t a reliable way to remove a blockage. Enzyme cleaners act more slowly on organic residue, so they’re generally used for maintenance rather than clearing an established clog.
