The bottom line

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 Ultra Hydra Source Conditioner draws complaints about dryness and weight.

Color Last Conditioner

Reviewers report their color looks noticeably fresher for several weeks without needing a touch-up.

colour-treated hair customers

Many reviewers describe the conditioner as lightweight and silky, not weighing hair down despite being conditioning.

general reviewers

A recurring complaint is that a reformulation made the conditioner feel harsher, leaving hair more brittle and unmanageable than the original.

longtime repeat buyers

Ultra Hydra Source Conditioner

Some reviewers report the thick formula and bottle design make it hard to dispense (no pump, cap resists twisting)

general users

A subset of reviewers report skin irritation/rash or limp hair after use

reviewers reporting sensitivity

Long-time users of the discontinued Biolage Conditioning Balm / Hydra Therapie Hydra-Seal formulas report this reformulation is not the same and leaves hair drier, coarser, or less soft than the products it replaced

decades-long users of prior Biolage hydrating conditioner formulas

Reviewers frequently ask for the brand to bring back the prior formula/packaging rather than praising the current one

$1.32/oz vs $1.42/oz — within about the same cost per ounce.

$0.09/oz median $1.60/oz $56.25/oz $1.42/oz Color Last Conditioner $1.32/oz Ultra Hydra Source Conditi

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.
  • 9 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.
