7 Most Popular Celebrity Hairstyles of All Time

Veronica Lake

In a time when most movie starlets were sporting perfectly coiffed or pin-curled hairdos, Veronica Lake set the standard for Hollywood glamour with her long, flowing hair. This style works best for thick, wavy hair, but it works on all face shapes. The style is usually parted on the side and can be worn falling seductively over one eye, à la Veronica, for extra drama.

Audrey Hepburn

In both Roman Holiday and Sabrina, Audrey Hepburn drastically cut her long hair into a super-short pixie — and made her male co-stars weak in the knees. The pixie cut was perfectly suited to Audrey's dramatic features (like her famous swan-like neck ), but the style will work on anyone who has an oval, square, or heart-shaped face and straight or wavy hair.

Grace Kelly

Of all the "ice blondes" that Alfred Hitchcock worked with, the flawlessly beautiful Grace Kelly was reputed to be his favorite. There was never a golden hair out of place in her many films, and her elegant chignon has come to be identified with her graceful sense of style. She married the Prince of Monaco in 1956 in a fairy tale royal wedding, and both her swept-back up do and her stunning gown have been coveted by brides ever since (in fact, Kate Middleton's gown was said to have been inspired by Princess Grace's).

Far rah Fawcett

The 1970s were known for voluminous hair, and no one popularized the long-layered shag more than Far rah Fawcett. The feathered hairstyle she made famous on the hit '70s show Charlie's Angels remains one of the most iconic of all time. Many of today's celebrities have given this sexy, full-bodied style a modern interpretation, including Beyonce, Madonna, Alicia Keys, and Heidi Klum.

Jennifer Aniston

Though she now wears her hair long and straight, Jennifer Aniston is best known for The Rachel, a medium-length layered look named after the character she played on Friends.

Sarah Jessica Parker

Now that she's a mommy in the city, Sarah Jessica Parker proves that cascading curls don't have to be prim and proper. For this easygoing 'do, scrunch a dab of alcohol-free gel into wet locks, then air-dry.

Victoria Beckham

This former Spice Girl became a hairstyle trendsetter when she debuted this graduated bob in 2006. The popularity of this cut was demonstrated by its nickname, "The Pob," which stands for Posh's Bob. The extreme angular cut accentuates Victoria Beckham's jawline and shows off her amazing cheekbones.

A Flat Iron May Soon Be Able to Color Your Hair

Along with straightening your tresses, your go-to styling tool may soon be doing a whole lot more. According to The Daily Mail, engineers at the University of New Mexico and Los Alamos National Laboratories are testing out flat iron-like devices that can color your mane without harsh chemicals or spending hours at the salon.

Using focused ion beams, researchers were able to change the hue of specific strandsand etch in patterns, too. And after trying the technique on different shades of hair (see the blonde tester above applying bright pink), researchers found that it worked best on brunettes, which is great for brown-haired ladies who want new colors without using bleach.
