The bottom line

The bottom line depends on your hair

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 a clean rinse-out. Davines The Purity Circle draws complaints about the price.

The Purity Circle

The single pouch is repeatedly called good value because it lasts many applications, from five uses on longer hair to ten or more on a short cut, used every one to four weeks.

repeat buyers

Hair comes out soft and shiny without feeling greasy or weighed down, which several reviewers contrast favourably with the other Davines masks.

general reviewers, including coarse dry and wavy hair

Reviewers describe the scalp feeling cleaned out and 'detoxed' after use, several on a stylist's recommendation, and a hard-water user says it brought back shine and colour brightness by clearing buildup.

salon clients, one hard-water user, short and long hair

The complaint side is that it does nothing noticeable: a minority felt no effect on hair or scalp and said the quality did not justify the price, while still rating the brand highly.

the 5% one-to-three-star reviewers, several outside the US

Pre-Shampoo Scalp Build-Up Remover

Reviewers with curly, coily or loc hair report it effectively lifts flakes and leaves the scalp feeling clean.

curly / coily / loc hair

Some reviewers say their hair feels lighter and easier to move or detangle after use.

general reviewers

Reviewers with long hair say the exfoliating grit is hard to rinse out completely and can get stuck in the strands.

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.
