Haircuts make my head cold

I'm sure this might be something that apply's mostly to guys but whenever I get a haircut my head feels cooler. I go about 4-6 weeks between haricuts so my hair is decently long by the time I actually get it cut. After I do get it cut it feels a bit drafty for a while and it takes some getting used to. On the upside, my hats don't feel so tight anymore when I wear them :)
