My eyebrows are sometimes so thin that I like to use a bit of pencil to make them darker and fuller. For years, I used no make-up at all, but at the moment I like to be very minimalistic and use it only on the eyebrows and eyelashes.
The best eyebrows pencils I have ever used are the ones by Benefit.
I am also thinking of you if you have lost your eyebrows and feel uncomfortable.
The key is to draw a straight line on their side then contouring the bottom of your eyebrows as I show in the video my friend my sister.
