Ha, yeah my hair used to spend half the day tied up in a bun anyway (and it was a straight up health hazard working in a chemistry laboratory with it!) and I've a high forehead (albeit with a still thick-as head of hair), so it wasn't the best look to begin with.
I got rid of the hair for similar reasons - was getting fed up of going to uni lectures dripping. But I did grow it again a few years after uni. But to be honest I was getting a bit thin on top and looked stupid.
Metal is an attitude, not a haircut.
