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.

Aveda Be Curly Advanced Co-Wash draws complaints about the price; Ouidad Curl Shaper Double Duty Weightless Cleansing Conditioner draws complaints about tangling and dryness.

Be Curly Advanced Co-Wash

Used daily/for years as a shampoo replacement for curly hair

Gentle, doesn't strip natural oils, good in-between-wash cleanse

Price has nearly doubled over the years, complaint about cost

Curl Shaper Double Duty Weightless Cleansing Conditioner

Reviewers with spiral or densely curly hair single it out as the one cleanser that lets them detangle in the shower, and some say it conditions well enough that a separate conditioner step stops feeling necessary.

Ulta reviewers with spiral curls, including the most-helpful positive review

Long-time repurchasers say the product was reformulated and that the current version no longer performs like the one they had been buying.

Ulta reviewer who calls it a former favourite

The strongest criticism is that it does not read as a cleanser: the scalp never feels clean, the product is hard to rinse fully, and hair is left frizzy and still tangled.

Ulta's most-helpful critical review, loose curls and waves, returned after two uses

Reviewers with thick, coarse hair conclude the formula is too light for their density and say it would suit fine or thin hair better.

Ulta reviewer, thick and coarse hair

Fine, thin-haired wavy reviewers report the opposite outcome: hair feels dry straight after washing yet turns oily again within a day.

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.
  • 4 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.
