Couldn't ask for a better hair coloring kit. I have natural dark brown hair and it covered it after one dye. I dyed it an intense red and was very pleased with the results. I hate when I have to buy a couple of boxes of hair dye just to get the effect I want. I suggest that if you do use it you will want to lay down painters drop clothes on the floor because the dye has a dramatic effect on any surface that it touches as well. The other thing I love about the kit is the conditioner it comes with. My hair always feels soft and healthy after I use the conditioner. It puts life back into your hair which is usually unheard of when it comes to dying your hair. The gloves that come in the kit are also great. I have used hair kits where vibrant colors leak through the gloves. The gloves keep the color from seeping through and they are very durable. There is nothing worse than getting hair dye on your skin and having to try washing it off. Effectiveness Covered everything Ease of Application It is the same as all hair coloring kits. Except the smell isn't overpowering.
