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.
Both praised for how it cleanses and strength and repair. Acure Ultra Hydrating Shampoo draws complaints about dryness.
Simply Smoothing Shampoo
Several reviewers specifically buy and use it together with the matching Simply Smoothing Conditioner as a paired routine rather than on its own.
reviewers describing their routineReviewers describe hair coming out noticeably smoother and shinier, holding up even in humid weather without frizzing.
general reviewers, one specifically on a humid dayA few reviewers with formaldehyde allergies or a history of scalp itchiness say the gentle formula lets them wash without a reaction.
reviewers who specifically mention allergies or past scalp irritationReviewers with fine or oily hair say it cleans without feeling heavy or greasy afterward.
reviewers with fine, breakage-prone or oily/thick hairUltra Hydrating Shampoo
Reviewers report noticeably softer hair and reduced breakage with regular use, crediting the clean/natural formula
reviewers seeking natural/clean-label haircareSome reviewers with thick or wavy hair report the shampoo leaves hair feeling dry rather than hydrated, despite the moisture-focused positioning
reviewers with thick/wavy hair textureThe formula has a notably thin/runny consistency, which some reviewers appreciate for easy lathering but others find unusual compared to typical shampoo texture
general reviewer baseFragrance is polarizing: many reviewers love the scent, but a vocal minority describe it as strong and unpleasant (compared to landfill/musty smells)

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.
$1.25/oz vs $1.32/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.
- 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.
