Manuka Honey & Yogurt Strengthen & Protect Oil

Curly and coily reviewers frequently credit it with taming frizz and adding shine after blow-drying or styling without heaviness

curly, wavy and coily-hair reviewers using it as a finishing or pre-blow-dry oil

Many reviewers describe the scent as pleasant and noticeable without being overpowering, and several specifically call out a honey/floral note

a wide range of reviewers on the Ulta PDP

Some reviewers say it did not noticeably strengthen or moisturize their hair compared to a plain conditioner, despite the product's claims

reviewers who tried it specifically for the strengthening claim

A very common complaint is that the oil leaves hair looking greasy, oily or weighed down, especially when more than one or two pumps are used

reviewers with fine, thin or straight hair, and some with thick hair too

Several reviewers say the oil sits on top of the hair rather than absorbing, leaving a plastic or waxy feel some attribute to Octyldodecanol on the label

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.
