I noticed that after the first pass and rinse that there's no pre-shave left. I use Castle Forbes pre-shave. Maybe 9 months ago, I experimented with oils versus water soluble and settled on the Caste Forbes. That was my DE shave days and it worked for me then. I now shave with an SR. I'm working through some scentless shave soaps, so that is a variable in my shave.
What role does the pre-shave have and what should I expect?
