Happy Birthday Jennifer Aniston! See Her Most Iconic Hairstyles [PHOTOS]

Happy birthday Jennifer Aniston! The 'Friend' turns 45 today (Feb. 11) and we're celebrating by looking at her best hairstyles over the years. Like it or not, Aniston is revered for her shiny, straight, face-framing locks, which she recently chopped into a bob due to damage.

She has admitted that she prefers her hair long and hanging around her lovely face; and while she is known for stick-straight, glossy, blond highlights, she has gone through lots of changes, styles and looks through the years.

We almost left off "The Rachel," the shaggy, piecey 1994 cut that put her on the map as a hair icon, for two reasons: 1) The oft-copied 'do is one that Aniston herself said she couldn't stand and well, frankly 2) neither could we. It was beloved at the time but didn't stand the test of time; you don't and won't see anyone in 2014 with "The Rachel" since it's not a classic cut. It was just a trend. But we still included it because, whether she liked it or not, it was definitive at the time.

These are some of our faves and the most memorable.

This is classic Aniston hair. Glossy. Golden. Angled. Face-framing. Fancy follicles.

We rarely see Aniston with a ponytail, but when she does go the off-the-face route, it's sleek and chic, like this 2010 'do.

Long layers, a center part and angles around the face are another Aniston strand signature, as evidenced by this 2013 snap.

Golden waves in 2004.

A sorta sideswept bang and a darker honey hue.

You can see the thickness of texture here. Her hair is actually naturally wavy, not pin straight.

Here are two Aniston hair rarities -- hairities? A dark hue and a ponytail. She dressed it up with the deep sweep side part back in '03.

Aniston was ombre, before ombre was a thing, back in 2003. Her stick-straight, glossy texture is evident.

Au naturel with chunky, defined curls in 2002.

In 2000, she was buttery and mega long, just like she likes it!

Damage lead to this -- a shoulder-skimming bob! She chopped back in 2001 due to all the extensions and stress she put her locks through.

A low and loose pony, worn in 2000, was a bit of an optical illusion, like a faux bob. That's what we call "effortless coif chic."

These dark, rich waves are probably the closest thing you'll see to Aniston's natural color and texture.

Her 2004 long and layered look is one she has perfected and revisited time and time again. Only here, the hue was much warmer. She was so pretty here, which was back in the Brad Pitt days.

It was like she stepped right off the beach onto the red carpet with bedhead waves in 2004!

Effortless long layers in 2013. Yes, it's familiar but it's also flawless.

A pony with fringe, worn in 2013. A slight update but still sexy!

Oooh, a sidebraid. She rocked this in 2013.

Shaggy layers and highlights. We love that it looked as though she raked product through her hair and went about her day. Long messy hair, don't care.

Lobbed and bobbed in 2011 -- easily one of her best "shorter" styles.

Jennifer Aniston was a very knotty girl back in 1999. These faux dreads were super edgy. We wish she'd have revisited them at least ONCE in her well-coiffed life.

And 'The Rachel.' While dated, it DID define her at the time. Sorry, Jen, don't hate us for including it.

And here's where Aniston is now... lobbed in November 2013, due to damage. Sometimes you just have to chop it all off and start over.
