I like to build my lather directly on the face, and while I have yet to master the whipped cream look, I usually have a good lather. I recently went on a trip overseas and no matter what I did I could not get a good lather. I altered the amount of water I used and soap, but it always seemed to dry out way to fast. When I came back home my lather problems were gone. Does anyone know what could have had caused such a drastic change?
