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.

Both praised for shine. 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

Nourishing + Coconut Milk Anti-Breakage Serum Leave-In Hair Treatment

Coconut scent is a standout, frequently called out as 'amazing'/'delicious' and prompting compliments

Repairs/prevents breakage in damaged hair - multiple reviewers report fewer split ends and stronger-feeling strands with regular use

Controls frizz and adds shine/softness with just a small amount, bottle lasts a long time

Lightweight, absorbs without leaving hair sticky, slimy, or greasy even for fine/oily-prone hair

Price check

$2.00/oz vs $5.92/oz — CHI Keratin Silk Infusion costs about 3× more per ounce than OGX Nourishing + Coconut Milk Anti-Breakage Serum Leave-In Hair Treatment.

$0.01/oz median $2.17/oz $76.00/oz $5.92/oz Keratin Silk Infusion $2.00/oz Nourishing + Coconut Milk

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.
