Usage notes[]

The word hair is usually used without article in singular number when it refers to all the hairs on one's head in general. But if it refers to a single hair, it takes the indefinite article (a hair), or if it refers to more than one hair, a few hairs, then it takes the plural form without an article, and needs a plural verb.

George has (-) brown hair, but I found a hair on the sofa and suspect he's getting some gray hairs.
George's hair is brown, but one hair I found was grey, so I think there are probably more grey hairs on his head as well.
