I have never used an eyebrow pencil. My eyebrows are naturally pretty well formed on their own.  But I must admit I've been wanting to make them a tad bit more arched and mainly even them out.  I was worried about having that typical "painted on look". Boy, I had nothing to worry about!  I made little marks to mimic my natural hair and I was amazed at how natural my eyebrows looked!  I couldn't even tell looking up close that I had done anything, but it made all the difference in the world.  Really, just adding in 6 more "hairs" and it totally changed the look of my eyebrows, but it still looks COMPLETELY natural.  Really amazing!
