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

Reviewers with fine or thinning hair report fuller-looking, bouncier hair and reduced hair fall/breakage after regular use with the paired shampoo

fine/thinning hair, some using in combination with the shampoo

Reviewers who used the discontinued Full Density line report the Full Rescue reformulation left hair drier, gummier, and less effective for hair loss/thinning than its predecessor

loyal users of the prior Full Density shampoo/conditioner line

Some reviewers find the bottle/packaging shape awkward to use (notably for reviewers with dexterity issues) despite liking the formula

users with dexterity concerns

A subset of reviewers in dry climates find it insufficiently moisturizing despite liking the scent and slip

users in dry climates

Scalp Sync Universal Conditioner

Reviewers with sensitive or itchy scalps report the conditioner reduces dryness, itchiness and helps the scalp feel calmer.

reviewers with scalp irritation/dandruff concerns

Reviewers, including those with fine hair, say the conditioner feels lightweight and does not weigh hair down.

fine-hair reviewers

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.
