Brown hair is actually thicker than that of lighter hair but not as think as red hair.
My hair is brown, how about yours? No hair here, but your hair would be the second most common color for human hair, only behind black hair. Neat, do you know why people's browns are different? I thought brown was you know.. just brown. Well there are variations from almost black to light brown. Mine is closer to the darker side I believe.
Its strands are thicker than those of fair hair but not as much as those of red hair.
