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.
After seeing all the rave reviews on Youtube, I thought I would give it a go. Super impressed. Works best for well groomed/shaped brows. I like a little more definition so I use a pencil to define the arch then the E.L.F eyebrow kit to fill in and fix the hairs in place. Awesome! My brows stay in place all day and it lasts well in humid weather. Will continue to use and recommend to others. I use the colour ash.
Tips: A better brush makes application even quicker!
