Closely followed by Season 6 :)

I love her hair in season 9 just loved it. But season 6 and Eight were also cute. :P

You beat me too it ebathory =) I love season 9 hair very girly and cute (love thta you added pics)

I like season 8, not too girly , it still looks like scullys hair, lol, now days she has blonde, brown, red, everything!

Definitely season 6! She had amazing hair! I als love season 4.=)

I Loveeeeeeeeeed Her Hair In Season Nine :D

I love her hair that length :D

Season 6 and season 9 fo sho!!! I looooove her highlights/streaks in her hair! and the bangs over her eyes! Omigod! its to DIE FOR! If my hair was like hers (eccept brown, instead of red) then i would sooo have my hair like tht! :D But alas, i am sadly a blonde. :'(

or season 8

i think her hair definitely improves it does look dreadful at the start, it starts to improve around season 4-5 and it stays quite good then, i really think that she looks quite good in the last episode 'The Truth' but no offence to her but in season 1-3 it does look pretty awful (sorry Scully/Gillian)
(i too would love her hair, in season 9 'the truth' but i too am sadly blonde D':)
