To get pin curls: dab gel onto the root of a small section of damp hair, then twirl that section of hair around your finger until you get to your scalp. (You can twirl in whatever direction you’d like the curls to flow.) Slide your finger out of the curl and pin the curl to your head. Repeat for your entire head of hair, allow hair to dry, then remove pins, and voila![1]

The classic style of the pin-up originates back from the 1940s. Due to the shortages of materials during WWII, this period of makeup is considered the "natural beauty" look.[20] The US was immersed in war-time economy, which put distribution restrictions on consumer goods.[21] General rationing was supported; women applied mild amounts of products. Despite the rations, "Women were encouraged to keep buying lipstick and to send letters to the front covered in 'lipstick kisses' to boost the morale of the soldiers."
