One notices in 1940s hairstyles that the hair just beyond the temples was often smooth or pinned back, making the voluminous curled areas appear ever poofier in contrast. Ever wonder why you don’t see pics of these women with long bangs in their faces (like the umpteen actresses on talk shows who constantly wipe their hair to the side)? There’s no Crystal Gayle or Kim K. hair here. And it wasn’t just fashion.
Able-bodied men were overseas, and women were manning the production lines. Long hair (or even one stray lock) could get caught in machines and not only injure the workers, but put production on hold until she was freed. Even Veronica Lake (of the oft-imitated peekaboo hairstyle) changed her style during the war effort, showing the dangers of untamed, unpinned hair.
This youtube video explains why safety is of the utmost importance during factory work.
The end result is a new and improved, less seductive 4’11” Veronica, donning the updo called the “Victory Roll.” Sleek = Safe. And as you can see in the video, from behind, her hair makes a dazzling V for victory.
Many stars wore them, including Rita Hayworth.
And Betty Grable.
Now you know why your vintage pin-ups often wear their hair in an updo, and why the Allies won the war.
