Most Popular Celebrity Hairstyles of All Time

Louise Brooks embodied daring flapper style in the 1920s. Her dramatic angled bob with bangs looks as fresh today as it did then. Straight hair works best for a sleek bob like Louise's, but wavy and even curly hair will work for longer, more free-flowing bobs. Plus, a swingy bob will flatter all face shapes.

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.

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.

Marilyn Monroe may not have been Hollywood's first platinum goddess, but few would argue that she was the most memorable. Marilyn's sexy white-blonde curls personified glamour in the 1950s, and have since been imitated by many celebrities including Madonna, Anna Nicole Smith, Gwen Stefani, Christina Aguilera, and Scarlett Johansson.

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 fairytale royal wedding, and both her swept-back updo 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).

First Lady Jackie Kennedy was always the picture of elegance, inspiring a nation with her sense of fashion. Although the big "bouffants" of the 1960s have since been modified, full and voluminous hair has never gone out of style.

Mia Farrow's fresh-faced beauty was the perfect match for the pixie haircut she sported in the 1977, which was softer and fuller than the extreme crop she wore in the 1960s.

The 1970s were known for voluminous hair, and no one popularized the long-layered shag more than Farrah 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.

Always current, Madonna changes her look to suit her musical mood. However, we think that the platinum blonde curly crop she wore during her "Who's That Girl" world tour is one of The Material Girl's most iconic looks.

Stylists agree that Meg Ryan's cuts are among the most requested. The piece-y shag she sported in 1998 is a great option if you have fine or medium-weight hair.
