50's pin curl

We all know that heat is bad for our hair. It breaks it, dries it out and can lead to hair loss. Though heat applying instruments have been used for decades by woman the smarter ones have used non-heat methods to achieve just as beautiful of looks without over processing their delicate hair follicles.
The 1950's women used "rag curls" and "pin curls" to achieve many different, ultra feminine styles. Here are some links to fantastic video's I found.
