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.
Both praised for moisture.
REPAIR-ME.WASH
Tropical pineapple/papaya-derived scent is praised as sophisticated rather than artificial.
general usersLightweight, creamy formula is easy to apply and rinses cleanly.
general usersVisible improvement on damaged, bleached hair -- reviewer reported softer, healthier-looking hair after air-drying, with others noticing the change.
bleached/chemically damaged hairThe brand-recommended rotation (using the treatment product in place of a regular wash) did not work for every reviewer; some preferred wash followed by treatment instead.
general users experimenting with routinePremium price (roughly $73 for the wash/rinse duo) is seen as worth it for damaged hair but a barrier for budget-conscious shoppers.

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.

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.
