Hi! I have dark brows but they are rather sparse and so I like to use products to fill them in.
When first attempting to apply this, I tried warming it with a finger and applying it with an angled brush... Don't even attempt, those brushes don't work with this, haha. You could maybe get away with a spoolie brush...
You will have to rub your finger around for a while, and even then it won't seem like a lot. Apply it against the natural lay of your hair, otherwise, it really won't show up. You may have to attempt this a few times, and even then it may not seem dark enough. If you clean it up with a spoolie brush, it will look pretty natural.
The picture above will confuse you, It is the color of a very light tinted chapstick if chapstick took forever to rub on your lips... But it is a pomade and not a cream so this is expected :)
