What owners say

What people report

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.

Matrix High Amplify Conditioner draws complaints about the packaging; Matrix So Silver Purple Conditioner draws complaints about hold.

High Amplify Conditioner

Reviewers with fine/thin hair report it adds volume/thickness without weighing hair down

fine hair

Several reviewers praise its detangling performance and pleasant scent

Multiple complaints about the bottle/pump design breaking, unrelated to the formula itself

A reviewer paired it with the High Amplify shampoo but felt the conditioner alone did not restore enough moisture after the shampoo left hair dry

So Silver Purple Conditioner

Reviewers with grey, white, or blonde hair consistently report the conditioner neutralizes yellow/brassy tones while leaving hair soft rather than drying it out.

grey/white/blonde-hair reviewers, several noting daily post-shampoo use

Frequently described as a good value versus salon-brand purple conditioners, with several reviewers calling out the price relative to effectiveness.

value-conscious reviewers, mostly Amazon Verified Purchase

Some reviewers note the purple tint effect is subtle and temporary, with a few reporting the toning does not last between washes and needs frequent reapplication.

reviewers seeking a stronger/longer-lasting toning result

Commonly purchased and used specifically as a pair with the companion So Silver Purple Shampoo rather than standalone.

reviewers describing routine use with the matching shampoo

Several reviewers caution that overuse can leave a purple cast, and describe deliberately limiting use to about once a week to control tint intensity.

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.
  • 10 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.
