general reviewers, several with damaged or colour-treated hair

Reviewers repeatedly describe the pump packaging as easy to dose, saying only a few pumps are needed to cover the whole head.

general reviewers

A handful of reviewers found the product too expensive for the result, saying it made little visible difference to badly damaged or bleached hair.

a smaller group of dissatisfied reviewers, one describing bleached blonde hair

One reviewer specifically objected to the amount of silicone in the formula, saying the smoothness it produced felt like coating rather than genuine repair.

an ingredient-conscious reviewer

Several reviewers say results build gradually, with little visible change after one use but noticeably better softness reported after a few weeks of regular use.

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.
