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.
Kevin Murphy ANGEL.WASH draws complaints about the packaging.
ANGEL.WASH
Delivers hydration without weighing hair down and performs reliably across fine and bleached hair types, per a stylist reviewer.
fine/bleached hair, salon-professional reviewNoticeably thickens and adds volume to hair without an overly airy or flyaway feel, drawing repeat compliments.
fine hairOnly a small (coin-sized) amount is needed per wash, which reviewers with fine, colour-treated hair feel justifies the price over time.
fine, colour-treated hairThick, rigid bottle design makes the product awkward to dispense despite the stylized packaging.
general usersFragrance is divisive: some reviewers find it pungent or overpowering while others describe it as fresh and sweet.
general users, personal scent sensitivitySMOOTH.AGAIN.WASH
Tames frizz on thick, coarse, or curly hair, especially in humid climates
curly/humid-climate reviewers (e.g. Texas)Improves manageability of fine, unruly, or aging hair texture over repeat use
long-term repeat purchasersSome reviewers find it hard to distinguish results from the brand's Killer Curls wash

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.
