some people try hair conditioner simply because that's what the goal is - condition the hair. And actually, although it may seem ghetto, the "shave secret" preshave/shaving oil at walmart is great product to try out. I actually really like the scent, and it's super cheap, i.e. >$3.

If you want to try a shave oil just to see what you think, I'd give the shave secret a try or the olive/castor oil combination Rob mentioned. Either way is cheap.
