Effective!

After only one use with shampoo and revitalization and I have already seen a difference. Effective for several days. I am chestnut and my hair went more towards chocolate after use.

After using hair dye a few times and having to deal with roots, I wanted an option of lightening my hair without the future issues. This product does not work for everyone but if you have lighter brown hair that isn't too dark, you will see that the product works. It looks like natural lightening and the color looks very natural!

The John Frieda Brilliant Brunette Visibly Brighter In-Shower Lightening Treatment is easy to apply, just get your hair wet and apply evenly concentrating on the roots, wait 5 minutes, rinse and Voila!! natural golden highlights and shinier hair, it is just a subtle change if that's what you are looking for. It does have a strong smell like ammonia, my hair was smelling like it all day, I also combined it with the shampoo version of the kit as recommended.
