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.

CHI Keratin Silk Infusion draws complaints about weight.

Keratin Silk Infusion

Works well across hair textures including wavy 2a hair, adding shine and health

Dramatically softens damaged/color-treated hair ("hasn't been this soft since I was a child")

Reformulated version feels thinner/more watery and underperforms vs. the original formula after flat-ironing

Protective Protein Hair Mist

Fights frizz without weighing hair down or leaving it greasy

Conditions and softens hair, makes it manageable

Contains silicones, a dealbreaker for silicone-free-preferring users (mild complaint/caveat)

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.

$1.99/oz vs $5.92/oz — CHI Keratin Silk Infusion costs about 3× more per ounce than Original Sprout Protective Protein Hair Mist.

$0.01/oz median $2.17/oz $76.00/oz $5.92/oz Keratin Silk Infusion $1.99/oz Protective Protein Hair Mi

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.
  • 8 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.
