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.

Deep Brilliance Deep Protein Masque

Strong overall satisfaction on Amazon: 4.6 out of 5 average across 331 ratings, an Amazon's Choice pick

Amazon aggregate rating, not individual quotes

Noticeably smoother hair after repeated use

Verified buyer review on BeautyCareChoices.com: "It has helped my hair. It smoothes out my hair and after using it now for two times it does the same"

Reviewer indicated intent to repurchase and recommend to others

Verified buyer review on BeautyCareChoices.com (same reviewer as smoothing theme)

GEMSTONE Color Protect Masque

A recurring caution is the 10-20 minute pre-shampoo dwell time, which some reviewers find inconvenient to fit into a routine despite liking the results.

Several reviewers describe using it as the first step right after a color appointment, often paired with the matching Gemstone shampoo and conditioner.

Reviewers consistently mention it leaves hair feeling softer and shinier without weighing it down, even for fine or aging hair.

Reviewers who color their hair, including vivid and red shades, say the masque noticeably extends color vibrancy and reduces fading between salon visits.

Price check

Cost per ounce against every product of this type we have priced, each at the size it is most often sold in. Value labels are computed from that percentile and from how many products that do the same job cost less; they are comparisons, not judgements about a brand.

$1.72/oz vs $6.84/oz — R+Co GEMSTONE Color Protect Masque costs about 4× more per ounce than CHI Deep Brilliance Deep Protein Masque.

$0.19/oz median $3.45/oz $24.50/oz $1.72/oz Deep Brilliance Deep Prote $6.84/oz GEMSTONE Color Protect Mas

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.
