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

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.

Both praised for the scent.

Healing Volume Shampoo

Several reviewers single out the scent and lather as favorites, saying they get compliments on how their hair smells.

general reviewers

Reviewers with fine, thin or flat hair repeatedly say it adds volume and fullness to their hair without weighing it down.

reviewers describing their hair as fine, thin or flat

Reviewers who also use the matching Healing Volume Conditioner say the two pair well together without stripping color or moisture.

reviewers using the shampoo and conditioner as a set

Curls Shampoo

Curly-haired reviewers report the shampoo helps define and control curls as part of a regular routine

reviewers with curly hair

Reviewers like the tropical kukui nut and monoi coconut scent

general reviewer base

Reviewers following curly-girl-method-style silicone avoidance flag the dimethicone/amodimethicone content as unwanted in an otherwise-liked product

silicone-avoidant curly-hair reviewers

A couple of reviewers with wavy (non-curly) hair reported the shampoo left their hair feeling flat, dry, or not clean, suggesting it suits curl patterns better than looser waves

reviewers with wavy hair

A reviewer perceived the formula as too protein-heavy, leaving hair frizzy and dried out, though the printed ingredient list has no hydrolyzed protein — likely a perception based on feel rather than formulation

Price check

Cost per ounce, in context

Cost per ounce against every product of this type we have priced, each at the size it is most often sold in. Value labels are computed from that percentile and from how many products that do the same job cost less; they are comparisons, not judgements about a brand.

$1.10/oz vs $3.62/oz — L'anza Healing Volume Shampoo costs about 3.3× more per ounce than Sun Bum Curls Shampoo.

$0.00/oz median $1.47/oz $17.29/oz $3.62/oz Healing Volume Shampoo $1.10/oz Curls Shampoo

Every mark sits on one distribution because these are compared against the same set: 805 shampoos with a computable unit price.

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.
  • 7 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.
