I've never tried brow powder. I like it but it might take a lot of practice to get it right. One thing I noticed is it doesn't stay on all day. I was disappointed in the color selections because I bought the lighter color, but it was too light and just not the right color. This brown is too dark. There is nothing in between. My hair color is silver.
My wife has been using this stuff for over thirty years. She says there's nothing else like it. The only problem is that it dries out after ten or fifteen years. Apparently you should buy only one at a time. She is very happy that they still make it, and hope it will always be available.
