I have recently purchased this in Ash. I have natural ash blonde hair. My eyebrows are plucked to the shape I want them, so this is used to fill in the gaps and keep them in place.
Ash is the lightest colour (as far as I know, please correct me if I am wrong) but I still find this a tiny bit too dark. I usually just use the wax, because if I use the powder my eyebrows get darker. Considering I am blonde, I don't want dark eyebrows.
It keeps my eyebrows in place all day, and the wax colour doesn't smudge.
I find the small brush applicator that comes with this kit is too short to get a defined brow, so I just use one of my angled brushes.
This does give my brows a defined, natural look but they need to bring one out that is another shade lighter.
I have this in medium. Having great eyebrows can change the look of someones entire face, and this defiantly delivers. I Have almost transparent brows, so I cant live with out a good brow product and this is at the top of my kit. Very affordable at $3-$5 and lasts ages. I find the wax side a lot better then the powder but it still does the trick.
Tips: Blend properly with the brush, to make your look flawless
