In reply to:
Can the word HAIR be classified as it's own plural. You say HAIRS in some circumstances (eg. there were two hairs in my soup) and HAIR in others (he has a full head of hair).
Not really. English, thank goodness, doesn't bother with noun genders much, but the difference between countable nouns and uncountable nouns (aka mass nouns) is crucial. For example pig is countable (1 pig, 2 pigs), pork is uncountable (and so has no plural). Some nouns can be either depending on the exact meaning, e.g. paper (the substance) is uncountable, but paper (= document) is countable (She threw the papers into the air in despair). Similarly hair can mean an (uncountable) collection or mass (I ran my fingers through his hair absentmindedly) or a (countable) item (He found two blond hairs floating in the soup).
