DAY 3 - experiment over for me, for now anyway. taking into account the comments regarding water out of the tap i might give this one more go in winter just to see.
Today's shave with room temp tap water, was not comfortable again. this was also with a new blade, a persona platinum. There are no post shave issues at all this time unlike yday, but the actual shave itself feels like i am tugging at the hairs instead of slicing through like a knife in warm butter. I guess my hairs are quite coarse and need to be softened.
I have not enjoyed the shaves without my usual prep, a warm shower. YMMV i guess.
