I have used Revlon hair products for years. To dye my hair, I use Revlon Colorsilk. It is a very inexpensive hair dye, usually about 3 to 5 dollars a box at many different stores. I have found that the color on the box is very true to the color you get when you dye your hair, unlike some dyes where it comes out different. The instructions are clear, precise, the solutions are easy to mix, and the whole process is easy to complete. There are no funny smells, what does smell is very sweet and faint, and the conditioner included in the box works well to mask any odor. You can also calla Revlon hair color expert at any time for any questions or concerns you have, as their number is right on the side of the box. Revlon Colorsilk is a great product, and I will continue to use it for years to come.
