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.
Kerastase Kerastase Densifique Bain Densite Shampoo draws complaints about dryness and weight.
Kerastase Densifique Bain Densite Shampoo
Reviewers who found it worked describe it as "saving" damaged/thin hair and worth the price despite the cost
repeat buyersReviewers report fuller, "lustrous" hair and improved body after use
5-star Target reviewersMultiple 1-star reviews complain of a strong, unpleasant "heavy perfume" scent and hair feeling dry after use
dissatisfied Target reviewersSeveral complaints are about shipping/packaging (late delivery, cracked/leaking bottles) rather than the formula itself
Target online buyersKerastase Specifique Bain Divalent Shampoo
Frequently professionally recommended - several reviewers say a hairdresser suggested the product, and describe using it as a periodic reset shampoo alternated with their regular one rather than a daily-only product.
salon-referred customersReviewers with color-treated, curly or wavy hair report improved manageability, control and shine alongside the oil control benefit, not just scalp cleansing.
colored / curly hair reviewersEffective at reducing scalp oiliness/greasiness with regular use without over-stripping hair, though several reviewers note results build gradually rather than instantly.
reviewers with oily scalp / fine or thick hairWorks well specifically for the oily-roots/dry-ends combination pattern (dual-action balancing), a distinct use case from a purely oily-all-over scalp.

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.
