HEART OF GLASS Intense Treatment

Reviewer with long-term color damage found it a genuine repair treatment (not just an extra-hydrating conditioner) that became a weekly self-care ritual

Editorial product review, NewBeauty.com

Makes hair noticeably softer and adds significant shine, with reviewer noting compliments even between salon visits

Blogger product review, paigeditullio.com

Delivers hydration without weighing down fine hair, and works in just 5-10 minutes once weekly

Blogger product review, paigeditullio.com

Complaint that the jar is pricey relative to how quickly it is used up (a few months of weekly use), harder to stretch than an oil or leave-in; scent described as mildly powdery though subtle and fast-fading

Blogger product review, paigeditullio.com

The Spotlight Circle

The no-weight claim holds up for the people most likely to catch it failing — fine, thin and baby-fine reviewers report softness and body rather than the flatness they expected from a mask.

several of 31+ reviewers on the brand's US store who described their hair as fine, thin, limp or baby-fine

Shine is the effect people actually get and the one they name first — reviewers describe dull, dry hair looking lit up again after a single use.

the dominant pattern across 31+ reviewers on the brand's US store

The fragrance is repeatedly mentioned as a reason to like it, with reviewers saying other people comment on how their hair smells.

several of 31+ reviewers on the brand's US store

Curly and colour-treated reviewers report curls staying defined rather than being flattened, and say colour looks more vibrant afterwards.

multiple reviewers on the brand's US store who named curly, 3a/3b/3c, highlighted or colour-treated hair, several of them stylist-recommended

A small minority get the opposite result and report hair going flat and lifeless within a day of using 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.
  • 9 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.
