My hair is brown, so I mixed Mocha Brown (which is darker) with Brown (which is lighter). I only used it to fill in parts of my eyebrows after getting them microbladed. It's convenient and looks natural. After using this, I find eyebrow pencils too intense to use.
There's a lot of excess powder fallout, and using just one shade can be tricky. The brush is also too short, making it difficult to apply.
