Review (4/5): Not a dye, but still good.
I bought it thinking of it as a dye. It is a huge disappointment in that area, but it gets four stars because it is a really good, easy to apply, brow definer. My eyebrows are very blonde, basically platinum, when fresh my brows are a nice soft brown. When I awake the next morning, they are a much lighter reddish brown. I will definitely buy again because I love the ease of application, but wish they wouldn't claim that it lasts 8 days.
