Not sure if they have one, did you know that brown hair is thicker than fair hair?
I don't think they have a name for them. My hair gets thick too, and fair hair is not as thick and not as much as red heads.
I have brown hair, quite common I guess. Yes, it is below black hair for most common hair color. And what is the least common hair color? Red hair naturally happens in 1 to 2% of the human population although I'm not sure fi it is the least common hair color. I say 1 or 2% probably makes it the least likely. Do you know what makes hair dark like my brown? It has to do with pigment. So high levels of eumelanin makes the hair dark while lower levels of pheomelanin make the hair lighter. Interesting.  And any idea what makes some hair curly? That I do not know. For brown haired people, they typically get called a brunette, do you get called that? I guess so, and how are people with black hair called?
Its strands are thicker than those of fair hair but not as much as those of red hair.
