Keep up with the weak hand work
I did this and it comes in handy as my left can shave certain areas slightly better than the right. I tested myself to see if I could shave left handed if the right was injured and without using the right hand for stretching and it worked. I tried this a few times to get the shaving down with my left hand. Now I can use my left with no hesitation.
With this exercise, I used every facial expression and head positioning to compensate for the loss of my right hand and my technique on shaving jumped a step. The next shave with my right, I incorporated a lot of the facial expressions and head positioning and the shave was such a breeze - BBS!
It was a beneficial learning experience for me and added to my proficiency.
