The bottom line

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 Shampoo draws complaints about dryness and weight.

Infra Moisture Therapy Shampoo

A reviewer managing a scalp condition (psoriasis) reported the shampoo left the scalp comfortable and hydrated with consistent use

sensitive/scalp-condition user

Reviewers who regularly use flatirons/heat styling report their hair becomes noticeably softer, shinier, and less dry

heat-tool users

Cleanses effectively without weighing hair down and has a mild, well-liked scent (some describe it as unscented/no perfume smell despite containing fragrance)

general users

A minority of reviewers report authenticity/counterfeit concerns with third-party Amazon sellers, distinct from complaints about the formula itself

Amazon marketplace buyers

Keratin Shampoo

Several reviewers with naturally coarse, thick, or frizzy hair found that this shampoo effectively tamed frizz and smoothed their hair while adding shine and softness.

Users report that this shampoo delivers optimal results when used as part of the complete Chi Keratin system, particularly when paired with the matching conditioner for enhanced softness and manageability.

Many reviewers report that this shampoo causes their hair to become excessively greasy or leaves a heavy buildup that requires more frequent washing or clarifying treatments to manage.

Multiple users experienced significant hair damage including breakage, excessive shedding, or severe dryness within the first week to month of using this product, particularly those with natural or previously damaged hair.

$1.26/oz vs $4.00/oz — CHI Keratin Shampoo costs about 3.2× more per ounce than CHI Infra Moisture Therapy Shampoo.

$0.00/oz median $1.48/oz $17.29/oz $1.26/oz Infra Moisture Therapy Sha $4.00/oz Keratin Shampoo

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.
