ok, I am hoping that you guys can help me out. I CANNOT make good lather anymore. I've been shaving with a straight razor for about 4 months now, and for about the first 3 i was fine, But now, every time I try and make lather it dries out super fast and isn't very thick. My soap bar is starting to curl around the inside edges of the cup, so im guessing that it's starting to dry out, could that be a reason?

every time i shave I shower first, soak my brush in my bowl while doing so, and strop before I shower. I condition my beard in the shower, then right after getting out i pour out my bowl and leave about a teaspoon of water in the bowl. I swirl my brush in my soap cup for 5 to 7 seconds, then begin to build lather for 1 to 2 minutes. I apply to my face out of the bowl to find that imy lather is drying within 30 seconds! I have tried more water, but any more and it gets way too runny. Is it possible that there is a large content of hard water coming out of my tap too?

IMPORTANT: I have also just moved approximately a month and a half ago, which is about when my lather started drying fast, which is why im guessing it's hard water content.

Please help... I love this hobby ad would like to continue, but I cannot if I can't find a solution to this problem.
