price-sensitive reviewer

ColorKick De-Brassing Shampoo

Effectively neutralizes brass and yellow tones on grey and blonde hair, enhancing shine and color blending.

Many reviewers with grey, silver, and blonde hair report the shampoo successfully reduces brassiness and brightens hair color.

Produces spectacular lather with a small amount of product, making it economical and efficient to use.

Reviewers note the shampoo creates rich lather that allows them to use less product per wash.

Can leave hair feeling rough, dry, dull, or straw-like, and may make hair appear yellowed or duller instead of brighter.

Multiple reviewers report the shampoo dried out their hair, made it feel rough or dull, or failed to improve brass appearance.

May not produce noticeable de-brassing results for some users, requiring alternative purple shampoos for effectiveness.

Several reviewers found the shampoo ineffective at neutralizing brassiness and returned to other brands like Amika or Redken.

How this page was made

  • This page is assembled from the same researched records the individual product pages render: identity, each ingredient list as printed, each brand's own claims, dated price observations, and review themes written in our researchers' own words. Nothing on it is written per comparison.
  • We do not rank these against each other. Which of them suits you depends on your hair, and that is what the consultation works out.
  • The formula similarity percentage is a stored, precomputed number: position-weighted overlap of the two ingredient lists blended with agreement on the attributes we derive. It measures how alike two formulas are, not how well either works.
  • The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
  • The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
  • 5 sources were consulted across the products on this page.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice. We do not sell these products and take no placement fees.
  • This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
