how to differentiate hair types?

[kinki_05]

i would like to know how to differentiate hair types.i m puzzled n confused about what is the difference between dry,normal n oily.how do i know what kind of hair i m having?

my hair tend to fall alot through combing n washing when i m having long hair.i had this problem whenever i keep long hair.i'm using head&shoulders now 'cos it helps with my dandruff.can i still use the shampoo n conditioner(without dandruff) that is available in the market?
my hair tend to start curly everywhere when my hair start to grow long.i would like to know is there any way to stop my hair curly n reduce hair loss?any good hair products to introduce to help me solve my problem?
