Just hang in there! I have done more than 100 hours of electro, and I am thoroughly sick of it. But I keep going every week, because there is no alternative.
Fortunately, at 100 hours, I started seeing significant changes. I had to bump up my "grow-out" from three days to four so she'd have enough hair to grab. Now, when I shave, my face feels baby's-butt smooth and stays that way all day. By evening, it is starting to feel a little un-smooth in places, but nothing is visible. In fact, even after four days of growing it out, you'd have to be looking for it to see any hair.
It's a long tunnel, but there is a light at the end of it, and it's not an oncoming train!
