That’s crazy, idk how you can keep it for that long of a time period. After 50-60 days I get so itchy it starts to bother me!
I wash my face with soap in the mornings and I clean it well in evenings during my showers, same way I wash hair.
Except for that I don't use any oils, creams or anything else for beard. Luckily, it's genetically very soft and doesn't itch at all
