I looked up my records. I started the journey in February and have had a string of issues.
It has been depressing reading of people who have it down pat in three weeks or so.
But! I have finally got it! Two straight weeks of low irritation, DFS shaves.
A number of factors have been required along with lingering worries when things have been pointed out. I have not had an unhealthy facination with BBS results, i don't need to stop using arko and only shave 2 passes with the grain. Dropping against the grain passes is not a solution to all my problems.
The missing piece fell into place when I realized that despite conventional wisdom, I did not need a with the grain pass. 8 months i did them with little real results and enough extra blade on skin to push my face over the edge for irritation. Probably because I shave every day rather than every second for example. This means i need an agressive razor so that i get through more on a pass.
Current routine: derby or arko soap. Gillette slim on 5. Shark stainless blade (have also tried rapira platinum lux with similar results). 1 pass cross grain (i leave the neck after this). One pass hybrid cross/ against grain. Against grain touchups. DFS face and CCS neck.
I am extatic at these developments.
8 months - don't give up.
