I have proraso sensitive shave cream, which I was getting great lather. Last night I added proraso sensitive pre shave to my shave. I wet my face, rubbed in the pre shave, and let it sit on my face while I created my lather. I applied the lather on my face (with a brush) over the pre shave and it seems the pre shave killed the lather. I didn't get rich thick lather, like I do when I didn't use the pre shave. The pre shave thinned it out, while I was applying. I have read on the boards that people love the pre shave by proraso and some wouldn't shave without it. Is it common that pre shave would diminish lather? Any suggestions? Thanks in advance.
