You can do litmus paper tests to see if there is too much base.
Grating can redistribute salt that some add -- salt burns but at exactly the right amount calms.
Fragrance and stuff... some give me a rash... an old soap will be kinder to my skin.
Just grating allows air into the mix and the first application of water fills a lot of the
internal voids and makes picking up an abundance of soap allowing a richer lather
with more cushion and glide.
A tossable hard soap can thrive with a tiny half pea size bit of a shave cream like Proraso.
It works for Williams....
SUMMARY: who knows what you did that turned the corner, I do not.
ENJOY the shave.
