Let's speak about Barbie style hairstyles. This particular hairstyle requires long hair, no short cuts, no complex pillings. As you already know, Barbie girl is romantic and windy, so it is important to have long hair accessorized with beautiful items, like scarves, ribbons, barrettes and bows. If you grew up from wearing bows, then you can always make bow from your hair (like Lady Gaga did some time ago).
Barbie style is youthful and happy one, so it means, women after 30 can't afford pink dress, that's why it's very important to choose clothing, make up and hairstyle very carefully and critically.
To look like a real doll you need blonde hair's color, that's an important point. There are three basic hairstyles.
The first one is quite simple, as it requires long, shiny and sleek hair where hair end length is aligned in one line. Use masks for a shiny effect and iron to make it look plain.
Second haircut requires light curly locks, it's easy to do you only need to use hair spray for fixation and heated curling. The lower hair layer has to be curled along the entire length, while top hair layer should be curled in two-thirds.
The third option of barbie hairstyle is a sport high ponytail, which is very sleek and with no shaggy effect. Gather your hair into tail and fixate it with band and then use hair spray to make it glamour.
