No head on my beer, but it is carbed, wtf?

That's the thing though, I've tried over carb-ing it by keeping it on 30 psi for several days. When I bleed the pressure down to get it to serving pressure, it is obvious by the gas released that the keg has been holding the pressure. I'm sure there is no leak because 1) I've used this keg many times and 2) my CO2 tank has not run out even while putzing around with this keg at 30 psi. I don't get it.

The beer tastes OK, but the lack of head makes it look like I'm drinking apple juice.

A few days at 30 PSI wont overcarb it my friend!

As to the oil posts; I doubt it had to do with oils, Ive done fresh hops + bakers chocolate (yes including the cocoa butter, was all I could get) and even that retains a good head when properly carbed.

shake the @#$% out of the keg at 30 PSI for a few mins
then leave it at 30 for a while longer; bet you end up with head
