Talika Brow Tintation At-Home Eyebrow Tint - DIY Natural Eyebrow Dye - Semi Permanent Long-Lasting Brow Tint, Non Oxidative Colorants - 4.2 ml

This product does not work. Having tried 30 minutes, I then left it on my eyebrows all night. When I washed in the morning my eyebrows were exactly the same. It you buy it, be prepared to use is every day, as you would a brow pen. It is not cheap and doesn't work.

Great idea and easy to use. Didn’t go quite dark enough for mid to dark brown brows tho In my opinion unfortunately.
