According to The Press Association, Jennifer Aniston's "Friends" cut, Twiggy's pixie, Madonna's bleached blonde tresses, and Marlene Dietrich's pin-thin brows are among the top "Beauty Trends That Shook the World."

My list would also have to include Audrey Hepburn's full brows, Veronica Lake's sculpted waves, and Marilyn Monroe's signature pin curls. They're each so iconic.

Which celebrities/hairstyles top your list of most influential?

The stars of the highly anticipated romantic-guide-turned-movie, "He's Just Not That Into You," walked the red carpet last night— each with a surprising new do.

Drew kept with her recent retro-inspired look and pulled everything back into a polished ponytail, Jennifer Aniston wore a ponytail as well (just when we thought she was updo-phobic...), Ginnifer Goodwin looked gorgeous in tousled waves, and Scarlett Johansson went board-straight and brunette for the big event.

Q: What are Sedu hairstyles exactly? I hear about them all the time and have no clue what they are ... –Rhomella L., New York

A: Not a worry! I've had many people ask me what "Sedu" is, and it's actually a brand of flat irons and styling tools that aim to provide smooth, sleek hairstyles (much like the ones that Jennifer Aniston made popular). So "Sedu hairstyles" are simply looks created by using a Sedu brand styling product.

What makes this particular brand so special is/was their use of cutting-edge technology. Sedu flat irons were one of the first to reach their max temperature within seconds (reducing styling time), omit negative ions for protection, and use special plates that could provide frizz-free results without catching or breaking the hair.

From being everyone's Friend to surviving the most awkward Hollywood break-up ever, one thing has always remained constant — Nothing can cause Jennifer Aniston to have a bad hair day. She's simply immune.

Jen's gone big, blonde, short, long, straight, wavy, and even experimented with dread-like twists, managing somehow to start a major hair trend with every snip or style. It must feel like both a blessing and a curse.

Which of Jen's looks do you love the most?
