Women of the 60's who wanted a more conservative version of the big bouffant opted for a tamed down puffy hairdo like this one. In the 40's and 50's many gals pulled their locks up in the back and this practice carried over to the 60's for some. Ratting the top portion and then smoothing over the top layer gave height as we see here and then the back was secured into an updo. Lots of Aquanet hairspray was used to keep those strands in place.
