L'Oréal Elvive Hyaluron + Pure Oil Erasing Scalp Serum for Oily Roots and Scalp draws complaints about dryness and residue or cast.

Elvive Hyaluron + Pure Oil Erasing Scalp Serum for Oily Roots and Scalp

The scent is very frequently called out as a favorite part of the product, independent of whether the reviewer felt it worked.

general reviewers

Many reviewers with oily scalps say it reliably cuts down greasiness and buildup, especially when used alongside the matching shampoo and conditioner.

reviewers with oily scalp/roots

Several reviewers with sensitive scalps report burning, tingling or itching during or after the 15-minute wait, sometimes to the point of stopping use.

reviewers describing sensitive scalp

A recurring complaint is that reviewers noticed no real difference in oiliness after using it as directed.

general reviewers

ProGrowth + Peptide Hair Strengthening Scalp Serum

Many reviewers say results were inconclusive after weeks of consistent daily use, with no visible change in hair growth, thickness or density.

A recurring complaint targets the twist/push applicator, which many reviewers find hard to unlock, prone to leaking, or breaking after a short time.

Some reviewers report the serum left hair or scalp feeling greasy, itchy or irritated, and a few describe a small bottle that runs out quickly relative to the price.

Reviewers repeatedly describe the serum as lightweight, fast-absorbing and non-greasy, leaving little to no residue on the scalp.

The fragrance-free formula is appreciated by reviewers with scalp sensitivity, though a few wished it had some scent.

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.
  • 10 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.
