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.

Olaplex Rich Hydration Mask draws complaints about weight.

No.8 Bond Intense Moisture Mask

Many reviewers say hair feels shinier, softer, and healthier after just a few uses of this weekly deep treatment.

Several reviewers with curly, coily, or frizz-prone hair say it tames frizz and holds curl definition even in humid conditions.

A recurring complaint describes shipping problems, including the product arriving leaking, frozen, or damaged inside the package.

A minority of reviewers say they saw no noticeable improvement despite recommendations and expected the results to build with more uses.

Opinions on the scent are split, with some reviewers calling it pleasant and others saying it is strong enough to bother sensitive noses.

Rich Hydration Mask

Reviewers with curly or coily hair repeatedly report visibly softer, more defined, less frizzy curls and reduced breakage after just one or two uses.

reviewers with 3c-4c curly and coily hair

Reviewers consistently praise the pleasant, non-overpowering scent and the thick, creamy, luxurious texture of the mask.

general reviewers

A recurring complaint is that the mask leaves hair feeling heavy, greasy or coated, especially on fine, oily or straight hair, or when left on longer than the recommended 3-5 minutes.

reviewers with fine, oily or straight hair

Several reviewers who miss the discontinued No.8 mask say this mask feels less effective and doesn't compare to it.

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.
  • 15 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.
