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.

Biolage Scalp Sync Shampoo draws complaints about dryness and irritation.

Scalp Sync Shampoo

Many reviewers say the shampoo visibly reduced dandruff and flaking within the first few washes, especially when used with the rest of the Scalp Sync line.

reviewers with dandruff

A few reviewers reported skin reactions such as neck or scalp irritation and hives, in at least one case tied to a known allergy to an ingredient in the formula.

reviewers with sensitive skin or known allergies

Several long-time users say a past reformulation made the shampoo noticeably less effective at controlling their dandruff than it used to be.

long-time repeat buyers

A large minority of reviewers report the opposite: the shampoo left their scalp and hair very dry or brittle, sometimes described as 'straw-like,' and required extra conditioning to recover.

reviewers with dry-leaning scalps or hair

Reviewers are split on the mint/menthol scent and cooling tingle: many find it refreshing, but a notable share call it too strong or medicinal-smelling.

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.
  • 6 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.
