Honesty, i find this is true of just about any oil after a while. My hair loves oil, though, and seeing how I'm mod cg, it never ends up being a problem for me.
As for Jojoba - I use it and love it. It makes a good sealer, and is supposed to be the closest thing to Jair's natural sebum.
It does not go rancid like many other oils do (especially cooking oils), and is great mixed with any essential oil.
Just don't use it on your skin.
I can't compare it to argan, in that I've never tried pure argan oil (tho I want to!), but I can say its fairly light, but not as light as say Grapeseed oil.
