It seem right now most grooming products are either hair oils (of which there has been an explosion), or more classic hair gels. You should go to a store and try different products and see which one you like.
I use Moroccan oil, I put it in my hair after the shower and it keeps them down nicely. But I'm sure hair gels would work too. I don't know which one is a good brand. My cousin likes Aveda.
A couple of observations:
1) these products do make hair a bit shinier, though they don't necessarily look like one has tons of sticky stuff, as old pomades did
2) oils are now formulated so that they get dry and don't stain (unlike old macassar oil). Still, one has to be careful for the first 10 to 15 minutes
3) but hair does feel slightly different to the touch
