Deep Parts
This style was made famous after the Big Sheep movie featuring Lauren Bacall. This was the time when the world war ended and women had started covering their hair in scarves showing only the deep parts.
No Part
Deep part hairstyle did not go too far and women started styling their hair in a new way. The no part was a beautiful way to showcase the hair which was even seen in the movies like Cass Timberlane. Lana Turner played a role in that movie and it was she who gained a huge appreciation for her style.
