There is a difference in color, it does not fully cover but it provides some coverage with a natural result. It was applied to hair with a few gray hairs, mainly on the sides which are the temples. Use a small brush or toothbrush to apply it better, not just your hands. The hold depends on the quantity, it does not create residue, etc. It easily washes off with shampoo, I consider it to be of good quality in terms of materials. It does not have a scent. In hot weather, of course, it becomes noticeable with sweat
