Once my son’s white-blonde hair sprouted, I have heard from countless people the expression “towhead”. I had never heard it before, and for some reason I wanted to take offense to it, so I did a bit of research on it.
I thought at first that it was spelled “toehead”, as in his head is so white it looks like a toe. That is completely wrong. Thank God.
It is “towhead” as in, a head of “tow”, which is “An untwisted bundle of fibers such as cellulose acetate, flax, hemp or jute.”
So there you go. It looks like their hair is made of hay. That’s all.
