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.

Both praised for moisture. Kerastase Discipline Masque Oleo Relax draws complaints about weight and the scent.

Discipline Masque Oleo Relax

Many reviewers with thick, coarse, color-treated or dry hair say the mask leaves their hair noticeably softer, shinier and much less frizzy, often citing it as a long-term staple.

long-time users with thick, coarse, dry or color-treated hair

Some reviewers with fine or normal hair find the mask too heavy, reporting that it weighs hair down or leaves it feeling greasy, particularly near the roots.

reviewers with fine or normal hair

A number of reviewers describe the fragrance as unusually strong, with a few reporting headaches or an artificial scent compared with the original version.

scent-sensitive reviewers

A recurring complaint from long-time users is that the current formula feels thinner and less effective than the original Oleo-Relax masque, and several ask the brand to bring the old formula back.

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.
  • 7 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.
