me to get in touch with my feminine side just for the sake of this

When Buffy the Vampire Slayer
hit the airwaves in 1997 as a television adaptation of an unremarkable
movie, no one ever expected the show to be a success let alone
establish itself as a part of modern philosophy.Books that philosophize the adventures of the Slayer have become the source for understanding the hidden meanings and subtle details in the BTVS universe. While these books appeal to the couch potato philosopher, they miss one crucial bit of analysis: Buffy's hair.
Probably
one of the reasons Buffy's hair has never become the topic of graduate
thesis is that it's really not what the show's about. But if various
minutia of the show can be the focus of a philosophical essays, then
Buffy's hair is fair game. With that being said, here is a
season-by-season analysis of the slayer's locks:

In season one, Buffy predominantly has an LA look. Her blonde hair with
dark roots is sprayed carefully to attain that elusive, rebellious LA
rock look. This style of hair clearly reflects the state of mind she is
in. She is rebellious, a bit edgy and tough. Her hair is statement on
its own it says. "I'm a teenage girl who wants to have a good time but
can't." Buffy is shackled with all these new responsibilities and the
only thing that she has control over is her style.

Throughout most of the season, Buffy has a short, straight look. Gone is the
hairspray and rank teen rebellion and in its place is a more innocent
looking Buffy. This season reflected, among other things, the innocence
of first love and the harsh realities of abusive relationships. Buffy's
hair outwardly reflects her feelings and really brings out the
innocence that she has as a young woman in love.

Throughout most of the third season, Buffy had her front bangs lighter than the
rest of her hair. This was a popular look for women in the late '90s.
Buffy carries this look well but is it a reflection on her character or
a just a fashion statement? Season three is the first season that Faith
the Slayer makes an appearance. Faith has dark hair and ... a darker
personality. Buffy, on the other hand, is fair-haired and this
particular season, almost bleach blonde. It's possible the contrasts in
their hairstyles are supposed to represent their characters'
personalities and opposing values.

straighter style. It's still a lighter blonde similar to the shade of
blonde in a previous season but the color is more even through out her
hair. Buffy's longer hair is a commitment to getting loose and letting
go a little. She's at college to learn and to have fun. While her
slayer duties are still important, she has a life to lead and she is
committed to being a normal college student.

Buffy now has even longer, wavier hair. It's a solid shade of golden blonde.
Hair does not predict the future but ,since this is the Buffy-verse,
anything is possible. Her hair can only be a sign of hard times to
come. The "waves" are going to crash down hard on Buffy. Season five
was a season of changes. It's important to note that Dawn was first
introduced in this season and that this is the season where Buffy's
mother passes away.

Buffy has two main hairstyles in this season. The first being the longer wavier style the second being the off the shoulder cut.

In the episode "Gone",Buffy's hair is used as a plot device to get the story moving. While
it's not the focus of the episode, it is still important because it
establishes the conflicted feelings Buffy has toward Spike. In this
episode, Buffy's hair is a metaphor for her relationship with Spike.
Buffy wishes she could cut the relationship like she could cut her
hair. In this instance Buffy feels the only thing she has control over
is her hair.

Buffy's got "mom" hair. Well, not really, but she worries that she does. She
has come a long way from being a rebellious teen to a semi-responsible
adult and, even though her character is still developing, she has made
considerable progress as an young adult and human being. Her hair in
the seventh season reflects that. It's shorter and often tied back.
It's a bit more manageable than previous seasons. Buffy doesn't have
time to fuss with it.
In short, when the creators of this show
were thinking about the philosophies behind this landmark series
throughout its evolution, they thought of everything. Right down to the
hair.
