I have ever since I got seborrheic dermatitis (was around the period I also started shaving) had problems shaving, which has left me inflamed bruises on my face.

When a friend told me he use to shave in the shower I was in a shock, it is almost impossible for me to do that.

I am wondering if this has something to do with seborrheic dermatitis? I saw a thread on Reddit where a guy said that he had the same problem, until he put white vinegar on his face and after that shaving became easy..

I am not sure I want to put white vinegar on my face though, what do you guys think?
