Learn English – “Hair” vs “hairs”


When we add s at the end of a word, it refers to more units of the thing. For example, a car vs cars.

Why is it that when we refer to hair, it is kind of the other way around?

1) Your hair looks great (comment on all your hair)

2) You dyed some of your hairs (comment on some of your hair)

Best Answer

Hair can be used as an uncountable noun:

You have too much hair

or a countable noun in which case its plural is hairs:

There are three hairs here.
