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 Weightless Nourishing Mask draws complaints about tangling and dryness.

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.

Weightless Nourishing Mask

Reviewers report noticeably softer, shinier and less frizzy hair immediately after a single use

fine to medium hair users

A minority of reviewers say the mask leaves hair dry, tangled or coated with residue despite the weightless marketing

mixed hair types

The whipped, silicone-forward texture reads as lighter than a typical creamy mask, which some reviewers found surprising given the name

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.
  • 13 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.
