I have brows!!!
I purchased this product in the blonde color from the Glossier web site.  I have always used either brow pencil or powder and am just stunned by this product!  I love it.  It actually colors and thickens the individual hairs.  Mine are so light, I didn't even realize they were there until I used this product.  For the first time in my life, I have normal and natural looking brows with very little effort.  Since the ends of my brows sort of fade out from the lack of hair there, after this product dries, I can go back and feather in a more elongated brow tail.  I watched a YouTube tutorial before using the first time to get an idea of how to use it.  Women with sparse or very light brows will love this product.
