Big problem with using hair is that it changes taughtness with the humidity in the air (didn't you do that barometer experiment with your own hair in 2nd grade? :)). On a humid day, your hair-aerial will sag seriously. On a cold day it could conceivably bend the mast.
I use 2# fish line for my aerials. Drill holes, attach with superglue. The trick is you don't HAVE to attach it perfectly tight. After the superglue sets, light a match, blow it out, and pass the hot smoke over the fishline. It shrinks. Pull the match away at the moment it reaches the right taughtness. Paint it. Yer done. :)
