bob—short woman’s haircut that was popular (but daring) in the 1920.  

The word “bob” was first used in the sense of “a horse’s tail cut short,” as in a “bobtail nag.”  The word “bob” came to be applied to women’s short hair when there was a drastic change in women’s styles early 1920′s.  Women who came of age in the 1920′s wanted to be modern.  They rejected the styles of dress and styles of thought of their Victorian parents.

Hairdresser were at first violently opposed to the new style.  They were used to curling, combing and brushing the traditional long hair and knew very little about cutting it.  Fashionable Women who wanted to get their hair “bobbed” had to go to men’s barbers because they were the only experienced haircutters around.
