I convinced both my girls to stop plucking their eyebrows a few years ago. They might pull the odd stray one. But in general leave them alone. They are both fair, so I think lighter eyebrows helps. And they just have a great shape to them. I however (and my oldest who is a boy) have the caterpillar crawling across the forehead kind of brows. I have to shape mine.
Mine are very dark and thick, so even with the plucking I have plenty of brow left.
Thanks! Circa 1989/90, I think.
