Bangs have always for the bold and fashion forward. They make a definite statement that takes some serious commitment. They can take forever to grow out, you know! Bangs can also very strongly show a particular period. So here's a survey of bang styles over the years.
Bangs in the 1920's were a bold way to set yourself firmly in the flapper style. Several film stars adopted a severe bob with blunt straight bangs but wispier bangs were not unheard of either.
Bangs in the 1930's moved away from the blunt style and tended towards the wispy look. They were also often curly.
While the U-shaped Bettie Paige bangs first became popular in the 1940s, curly bangs were also popular. These bangs were fuller than looks from the 1930s. Most often, however, the bang area was a rather long fringe that was styled into the rest of the hair to give a peak-a-boo wave. The Middy haircut had this type of bang.
Bettie Paige bangs continued to be popular in the 1950s. Rolled bangs were an option for those who didn't want bangs every day. Softer bangs a la Audrey Hepburn also began to appear.
