The bottom line

The bottom line depends on your hair

Which of these two suits you is a question about your hair, not about them. The consultation answers it — and tells you what your routine needs around it.

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings, and we never balance one product’s themes against another’s by inventing them.

Color Extend Blondage Color-Depositing Mask

Go-to maintenance between salon visits, leaves cool-toned platinum blonde hair soft and vibrant

Walmart reviewer "Amber", 5 stars, Oct 2025

Works as expected for anti-brass toning

Walmart reviewer "Thomas", 5 stars, Jul 2026

Used alongside Blondage shampoo, helps reduce (though not fully eliminate) brassiness

Walmart reviewer "Christine", 5 stars, Jan 2026

Extreme CAT Anti-Damage Protein Reconstructing Rinse-Off Treatment

Many long-time users, including those with bleached, highlighted or over-processed hair, describe the treatment as restoring strength and manageability after years of visible damage.

Several reviewers report noticing no difference at all after use, describing the product as feeling like plain water sprayed into their hair.

A handful of longtime users report the product was reformulated at some point and are unhappy with the new scent or ingredient list compared to the version they had used for years.

Some reviewers caution that overusing the protein treatment without following with a moisturizing conditioner or mask can leave hair feeling hard, brittle or overly tangled.

A recurring complaint is that the spray-pump bottle is awkward to grip and dispense while wet in the shower, forcing some reviewers to spray it into their hands first.

Price check

Cost per ounce, in context

Cost per ounce against every product of this type we have priced, each at the size it is most often sold in. Value labels are computed from that percentile and from how many products that do the same job cost less; they are comparisons, not judgements about a brand.

$4.35/oz vs $5.00/oz — within about the same cost per ounce.

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.
  • 9 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.
