The bottom line

The bottom line depends on your hair

Which of these two suits you is a question about your hair, not about them. The consultation answers it — and tells you what your routine needs around it.

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.

SU Hair Mask

Perfect aggregate rating on a smaller review base: 5 out of 5 stars across 2 Influenster reviews

Aggregate Influenster.com star rating, disclosed as aggregate from a small review base

Strong aggregate customer satisfaction: 4.7 out of 5 stars across 21 Amazon reviews, Amazon's Choice badge

Aggregate Amazon.com star rating, disclosed as aggregate (individual review text not accessible)

Salon senior colorist reports a real client whose colored hair went brassy and straw-like after a week of river/sun exposure regained calmer tone and soft ends by her next visit using this mask after each sun/water exposure; salon stocks it because stylists use and trust it themselves, calling it close to essential for colored hair through an outdoor summer, while noting it maintains rather than rebuilds severely damaged hair

The Let It Go Circle

The small 50 ml jar is valued as a travel format in its own right, not just as a trial size.

a reviewer on the brand's UK store; the small format is the only size the US store sells

The result people describe is softness and silkiness that holds for several days rather than washing straight out, and it is reported by both very fine and very long hair.

four of seven reviewers on the brand's UK store, including one with thin hair and one with extremely long hair

Reviewers with scalp trouble single this out as one they can use without a reaction — an irritated, flaky scalp settled down, and a scalp-psoriasis sufferer reports no irritation.

The scent is called out as a reason to keep buying it, and reviewers say the shine it leaves draws unprompted comments from other people.

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.
  • 11 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.
