Years and years ago, my darling hairdresser told me to use the Clairol Professional Shimmer Lights Shampoo once a week to take the brassiness out of my blonde highlights. If I  had to guess, I would say I have used this shampoo for at least 20 years. I purchase a big bottle of the shampoo about once a year, and I’m so OCD that I have to use it every Monday morning or I will forget if I used it or not that week! 

I think it does a great job not only cleaning my hair but also keeping it blonde  and shiny.

If you have blonde hair that looks more yellow and dull, you need to try this stuff.

From Clairol Professional:

Protein-enriched conditioning formula tones down brassiness on blonde and silver hair, renews and refreshes faded highlights and ash-toned hair, removes the dull yellow in silver hair, and leaves hair shiny without residue.

Clairol Professional Shimmer Lights Shampoo also comes in Brunette and Red, which will enhance gold tones for dull light brown and fading red hair and add radiance to strawberry blonde and red hair.
