Bombshell hair can mean many things - from the 50s to the 90s big hair has always signified power, money and glamour. There's no one particular style, but all of these hair styles have a few things in common. Firstly, bigger is always better - and that means volume at the roots of the hair. Beautiful waves and curls are another feature, but bombshell hair can also be almost straight with just a flick at the end. Bombshell hair says 'look at me' - it isn't a look for the faint hearted.
