Doesn't work on dark hair
Obviously, few of these products really do, but there was a picture in the item description of a person with jet black hair applying the chalk, so I chanced it. My son has kind of medium brown hair, not nearly as dark as the photo, but the only thing you could really see was some colored water on his scalp. The reviews are very stacked in this feedback section, definitely some fake profiles giving favorable reviews to give an inaccurate rating.
