Oh! Also RevitaLash. It’s more expensive, but I was desperate so I got a few different brands just in case and still alternate. It worked on my eyelashes, too (sadly that’s just bad genes - never had long ones). This morning I just did a little trim with some small scissors, and I’m happy with that. It really was odd to find something that worked as advertised. I wish your wife happy, crazy, out of control eyebrows! :)
