The bottom line

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 the scent and volume.

Plant Based Stem Cell Shampoo™

Multiple reviewers report improved hair thickness/fullness with continued use of the shampoo+conditioner system

Praised for improved scalp health alongside hair thickness

Scent is called out as a strong positive

A reviewer found the system drying for their hair despite liking the scent

Full Body Weightless Shampoo

Several reviewers note it pairs well with the companion Full Body Milk Conditioner for a full volumizing routine.

reviewers using the paired shampoo+conditioner routine

Reviewers describe a pleasant, mild scent as a secondary selling point.

general reviewers

Reviewers with fine or thinning hair report the shampoo cleanses well while adding volume and bounce without weighing hair down.

fine/thin hair reviewers

A few reviewers said it lathers lightly rather than richly, which some found reassuring for a sulfate-free formula and others wished were more foamy/cleansing.

reviewers used to sulfate shampoo lather

One reviewer in a humid climate cautioned the formula is more moisturizing than expected and can feel too rich at high dew points.

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.

$2.17/oz vs $4.20/oz — Act+Acre Plant Based Stem Cell Shampoo™ costs about 1.9× more per ounce than Curlsmith Full Body Weightless Shampoo.

$0.00/oz median $1.47/oz $17.29/oz $4.20/oz Plant Based Stem Cell Sham $2.17/oz Full Body Weightless Shamp

Every mark sits on one distribution because these are compared against the same set: 805 shampoos with a computable unit price.

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.
  • 8 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.
