How do I keep my avitar bald?

I have a constant recurring problem with my hair. I am bald by choice, yet there always seems to be a lump of hair inside my av's head that pops out the back whenever I look down. This is not a purchased skin, it is one created by me in SL. Allthogh all the hair settings are set to zero, it still comes through badly when being active. I would simply not like to see any hair on my head except eyebrows and the goatee.
Anyone have suggestions?

Welcome to the forums, Tensor! You need to wear a "Bald cap", which comes with any prim hair. Look in your inventory for "bald" or "baldie". The icon for it should look like a little brown wig.

I'm going inworld soon, I'll see if I have any with trans permissions. If so I'll drop one on you. Note that your eyebrow position and color are also in the bald cap!!
