Well, my electrologist and I worked out some strategies.
First, I make my appointments for Mondays, so for the three days of growth I initially needed, the 'last shave' was Friday morning, and the weekend was in hiding.
My electrologist concentrated on getting the 'muzzle' cleared first, the upper and lower lip and chin. These are the most obvious areas for others to spot hair growth. After a few months these tended to be free of thick and easily seen hairs, and the growth for electrolysis was mostly immature finer hairs, more easily hidden.
I used a hair style that largely covered the cheeks and jawline, hiding some gender cues and hair growth. Rolling on that concealer helped as well. The finer hairs are more easily hidden.
At over 180 hours in, I can finally get away without shaving for many weeks at a time. In Monday's session I actually had some hairs that were 1/2" to 3/4" long, but they were fine, almost invisible, and mostly fairly far back on the cheeks and jawline so they were hidden by the hair. My electrologist is on vacation now, so no chance of a sudden opening occurring for me to grab more hours, and I am keeping the remaining hairs shaved.
