Curlsmith Feather-Light Protein Cream draws complaints about weight and the scent; Curlsmith Root Boost Uplifting Spray draws complaints about dryness and frizz.

Feather-Light Protein Cream

First leave-in-style product usable without leaving hair limp; loves the high protein content, calls it a staple

brand-site reviewer with high-porosity, fine-textured, low-density hair

Completely eliminated the struggle with her hair; now has soft, manageable curls with easier detangling

brand-site reviewer with 3c/4a fine, thick African-American hair

Smelled nice but caused a burning scalp sensation, and the cream felt too heavy for her hair

brand-site reviewer, hair type unspecified

Worked well at first, but overuse led to protein overload; now uses it sparingly to balance protein and moisture

brand-site reviewer

Root Boost Uplifting Spray

Gives long-lasting lift at the roots with no added frizz

Ulta reviewer, very curly hair type

Delivers noticeable big-hair volume at the roots without drying out the hair

Ulta reviewer

Caused frizz for a reviewer who normally doesn't have frizz issues

Ulta reviewer

Not suited to fine 3a/3b curls; flattened roots and felt stiff like hairspray once dry

Ulta reviewer, fine curly hair

Berry scent stood out; product feels sticky on hands during root application but holds volume once dried upside down

Ulta reviewer, curly hair

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.
  • 3 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.
