My hair is fine and low porosity. I apply minute amounts of product to soaking wet hair and wrap in a Curlease towel to dress and apply make up without dripping. Then, I scrunch with a CLU towel and diffuse upside down for a few minutes. It helps to set the curls. I don't touch my hair with ANYTHING, including the diffuser, other then to part my hair with a fingernail to part it and clip my side swept bangs out of my eyes (one clip each side.) Not touching or adding more product seriously reduces frizz for me.
