In the mid 60's I was about 20 then, and very much into copying film star hair.My hair was shoulder length and quite thick, and I wanted to achieve the wavy longish glamorous styles. I would usually have to put my hair in rollers of different sizes, and sleep in them, which is not much fun. It was quite a common sight, to see lots of young women, who were going out dancing on a Saturday night, just going to the local shop for something, with all their hair still in rollers, to keep them in longer,for better waves,then to brush it all in style just before going out, after they had done their make up.
I used to have to use loads of hairspray, which always seemed to be very stiff and rigid, and if it got wet in the rain, it would go all gunky and matted looking.
A lot of girls liked wavy or curled hair then, But if you liked rock and roll and jiving like me, a ponytail was the way to go.
