In the early 70’s for young women, the look was straight hair, ... like Marsha Brady.
Yes, usually with a part in the middle.
First thing I noticed about my wife to be was her long hair.
Those were the days.
Just google any picture of Karen Ann Quinlan and you’ll see every ‘70s girl’s hairstyle.
In 1971, the shag hairstyle was all the rage. The big decision of the summer was: were you going to get your long straight hair cut before or after your senior pictures? I opted for after. My hairstyle in my senior picture was long and straight... like Julie from Mod Squad (who I was told I looked like). That fall I got my first long shag and I've had it layered to some extent ever since.
Yup—they used to use soup cans for straightening curlers.
