I wax my eyebrow hairs into an arch shape about once a week or so. My eyebrows are not that dense so when I wax and trim them I need to fill them in with eyebrow powders and colored cream or pencil product. I tried this Birchbox sample product on top of my usual regimen and could not really tell any difference in control. I figure this product is more for the bushy-unruly eyebrow-haired women in the world.
The product also has a strong, glue-like scent that was a bit of a turn off.
