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.
Strengthening Shampoo
A recurring complaint across many reviewers is scalp irritation, itching, dandruff or dryness that they attribute to the formula.
A recurring subset of reviewers, across many years of reviews, report noticeable hair shedding or breakage after use and stopped using the product.
Reviewers frequently single out the long-lasting, pleasant scent as the shampoo's strongest feature, especially paired with the matching conditioner.
Several reviewers with fine or thin hair report the shampoo weighs hair down or leaves it feeling heavy and greasy.
Many reviewers say the shampoo lathers well and cleanses without stripping or drying, leaving hair feeling soft and easy to manage.
Volumizing Shampoo
A recurring criticism is that it does not lather much, and reviewers with oilier scalps say it is not strong enough to fully clean their hair.
Several reviewers describe a cooling, refreshing sensation on the scalp and reduced oiliness after use.
The cucumber-mint scent is frequently praised as fresh and balanced without being overwhelming.
Reviewers say the shampoo cleanses thoroughly and rinses with no residue while adding lift or volume to fine hair.
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.
$0.67/oz vs $0.67/oz — within about the same cost per ounce.
Every mark sits on one distribution because these are compared against the same set: 817 shampoos with a computable unit price.
Computed from cost per ounce against every product of this type we have priced, and from how many products that do the same job cost less. It is a comparison, not a judgement about the 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.
- 12 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.
