Why is my scalp so dry and flakey?

Anonymous
For the past few week my scalp has been sooooooooo dry and even a bit itchy. My hair is naturally kinda dry and straw like but I have never had much of a problem with dandruff ever in my life but recently I dandruff like crazy. Whats wrong with my scalp and how can I fix it? Please help! :(
