All you have to do it buy a pencil! I learned this trick at a salon, with an eyebrow specialist. I complained about my eyebrow never being completely filled, since hair is always falling off and I have one part of the eyebrow that is not as thick as I wanted.
So she told me to go to buy a pencil, specifically a Faber Castell 2B pencil. It works for all colors of eyebrows and it looks really natural! I bought it and tried to round the tip, so it would be easier to slide it throught the eyebrows.
All you have to do is pass it slightly on the areas where you want to correct it. After that, I never felt bad about the lack of hair on my eyebrows anymore.
