I have always been soooo low-key with my brows. I pluck maybe once a week - I rarely have strays and they have a nice natural arch and shape. So, I don't do my brows every day because I'm lazy.
However, I feel that my brows aren't thick enough. They are a nice width from top to bottom, but there just isn't much in between. Does that make any sense? I feel it makes them harder to see - I mean, there's enough there so they're not skinny, but the depth of them I guess. I guess because I have fine hair, I have fine brows. So, when I do them, I use the Browser kit from NYC. (Used to use Benefit's, but NYC's color is better on me, and about $20 cheaper!) Just to give them more depth.
I did recently go to the salon and have my girl put dye on them. I have red hair but she used a brown dye - my brow color is like an ash blonde, and she said red dye would have looked crazy. I'm glad I trusted her - it was soooo subtle, but I noticed a slight difference - they just popped a little more. I don't even think my bf noticed though. It was pretty funny in the salon though, because the dye turned black and kind of swelled up - I looked like Groucho Marx!
