Hair grows in cycles, with different hairs on different cycles. Be patient.
Anecdotally, it seems that many trans women end up taking 150 or so hours to clear their face when using electrology as the chosen method of hair removal. Of course, some are more, some are less, and the range is wide, not narrow.
My electrologist told me the fastest clearing she ever did was about 30 hours total. That's at E3000 where they clear the entire face, even using 2 technicians at a time if you need it. The person in question came in twice, for about 15 hours each time, and when the time for the third appointment came, they canceled, came by anyway, and showed them their face was completely clear.
The longest case I know of took 4 years and over 400 hours to fully clear (about 2 hours a week at a more typical electrologist).
