This morning's post got me thinking that I may have neglected my eyebrows as part of my style.  I have always wanted to get my brows done professionally, either waxing or threading, but I have thin brows and am a little worried about a procedure which only takes away and doesn't add.  Are there any eyebrow people (for lack of a better term) who also show you how to fill in thin areas in addition to pulling strays?  I sometimes try an eyebrow pencil or powder myself but whenever I do it, it looks too heavy.  Does anyone else have a similar concern about getting your brows waxed when they are already thin?  What do you do to keep them looking their best?
