Eyebrow tinting is great for those who are starting to get gray hairs within their eyebrows. It is also great for darkening eyebrows. Caution: There may be some hydrogen peroxide in the ingredients. Those who are PPD allergic or who are sensitive to haircolor- should use caution.
The Godefroy brand pictured says it lasts six weeks. The color options are jet black, light brown, medium brown, and dark brown. This eyebrow color should NOT be used for your eyelashes. I assume it can cause blindness especially since the word "permanent" is listed on the box.
