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 moisture and how it cleanses. As I Am Rosemary Shampoo draws complaints about the packaging.

Rosemary Shampoo

Cleanses effectively without stripping natural oils; several reviewers describe the result as light, moisturizing, and nourishing.

General/mixed hair types, family use mentioned

Good lathering and easy application called out favorably.

General reviewers

Shipping/packaging complaints: at least one reviewer received a bottle that had leaked/spilled in transit.

DTC/online order context

Strong, invigorating peppermint/rosemary scent is polarizing: some reviewers enjoy it, others find it too strong or medicinal (one compared it to pine cleaner).

Scent-sensitive reviewers

Core Strength Shampoo

Pleasant guava-like scent frequently called out

general reviewer base

Restores a strengthened, refreshed feeling to hair after heat or chemical damage

reviewers with heat/chemical damage

Gentle without over-drying already-weakened hair

international reviewers, damaged hair

Used successfully for gentle daily cleansing on children's and teens' hair

parents of younger curly-haired users

Cited as a go-to for helping curls hold definition longer between washes

general reviewer base

$0.00/oz median $1.47/oz $17.29/oz $1.21/oz Rosemary Shampoo $2.17/oz Core Strength Shampoo

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.
