AGoodShampoo uses a small group of editorial author identities to organize coverage around different areas of hair care.
The names listed on this page identify the editorial voices used on AGoodShampoo articles. They should not be interpreted as a claim that AGoodShampoo is associated with any public figure, celebrity, brand founder or other person who happens to share the same name.
We do not add degrees, certifications, medical credentials, salon careers, cosmetic-chemistry qualifications, years of professional experience or personal product-testing claims unless those details have been independently documented for the individual author.
What matters most on AGoodShampoo is not an impressive-sounding biography. It is whether an article follows the site’s research standards, distinguishes facts from marketing claims and gives readers useful guidance without overstating what a hair product can do.
Meet the AGoodShampoo Authors
Carolina Herrera
AGoodShampoo role: Editorial author focused on damaged and chemically processed hair.
Topics covered: Damaged hair, bleached hair, color-treated hair, chemically processed hair, breakage, conditioning, protein-related topics, repair products and treatment compatibility.
Editorial focus: Carolina’s assigned coverage looks closely at how shampoos, conditioners and treatments may affect hair that has been weakened by bleaching, coloring, heat or chemical processing.
Articles under this author identity should pay particular attention to conditioning, friction, breakage, proteins, oils, silicones and claims about repair. Cosmetic improvements such as softness or reduced breakage should not be described as complete reversal of structural damage unless appropriate evidence supports that conclusion.
This topic assignment is an editorial focus, not a claim that the author is a licensed cosmetologist, salon professional, cosmetic chemist or medical specialist.
AGoodShampoo currently publishes articles under the Carolina Herrera byline, including coverage of shampoo selection and treated-hair topics.
Emily Turner
AGoodShampoo role: Editorial author focused on ingredient transparency and natural or sustainability-related hair-care questions.
Topics covered: Natural hair care, clean-beauty claims, ingredient transparency, sustainability, vegan claims, cruelty-free claims, packaging and environmental marketing.
Editorial focus: Emily’s assigned coverage looks at what terms such as natural, clean, vegan, cruelty-free or biodegradable actually mean in the context of hair products.
Articles under this identity should separate verifiable certifications and product facts from broad environmental or ethical marketing. A product should not be described as safer, healthier or more sustainable merely because the packaging looks natural or the brand uses plant-based language.
This editorial focus should not be interpreted as a claim of formal environmental, scientific or professional qualifications unless such credentials are separately documented.
AGoodShampoo maintains an existing author archive for Emily Turner at:
Author archive: https://agoodshampoo.com/author/emily/
The archive contains articles published under the Emily Turner byline.
Marlena Stell
AGoodShampoo role: Editorial author focused on everyday hair-care decisions and practical guidance.
Topics covered: Beginner hair care, shampoo and conditioner choices, simple routines, common consumer confusion, product selection, realistic expectations and everyday hair-care decisions.
Editorial focus: Marlena’s assigned coverage is intended to make complicated product choices easier to understand.
Articles under this identity generally focus on questions such as which type of shampoo may suit a particular hair concern, how products fit into a routine and what results are realistic to expect.
This assignment does not mean AGoodShampoo is claiming that the author is a licensed beauty professional, wellness coach, medical professional or salon practitioner.
AGoodShampoo publishes a substantial number of articles under the Marlena Stell byline, including everyday shampoo selection and brand-review topics.
Michael Chen
AGoodShampoo role: Editorial author focused on formulation and ingredient analysis.
Topics covered: Shampoo formulation, surfactants, silicones, proteins, preservatives, pH, ingredient safety, cleansing systems and evidence-heavy product analysis.
Editorial focus: Michael’s assigned articles place greater emphasis on how a formula works as a whole.
That may include examining surfactants, conditioning agents, preservatives, proteins, silicones, oils, fragrance and other relevant components. These articles should also distinguish ingredient-based interpretation from evidence involving a finished product.
The Michael Chen author identity should not be presented as having a degree in chemistry, cosmetic science, medicine or another scientific field unless that qualification has been separately verified.
AGoodShampoo maintains an existing author archive for Michael Chen at:
Author archive: https://agoodshampoo.com/author/michael/
The archive includes formulation, dandruff, shampoo-review and ingredient-focused articles published under that byline.
How Authors Are Selected for Articles
AGoodShampoo does not assign articles randomly.
Topic fit determines which editorial author identity is used.
A page about bleached or chemically processed hair may be assigned to Carolina because that editorial focus emphasizes damage, conditioning and repair claims.
A discussion of vegan labeling, sustainable packaging or clean-beauty terminology is more likely to fit Emily’s assigned coverage.
A straightforward consumer question about choosing between shampoos or building a basic routine may fit Marlena.
A formula-heavy article about surfactants, preservatives, proteins or ingredient evidence is more likely to be assigned to Michael.
This system helps maintain a consistent point of view without pretending that every author has professional qualifications in every part of hair care.
The article still has to satisfy the same research and accuracy requirements regardless of the byline.
What Our Authors Are Expected to Follow
Every AGoodShampoo author identity operates under the same editorial standards.
Writers are expected to:
- distinguish verified product information from manufacturer marketing
- use current product and ingredient information whenever practical
- check formula changes and regional differences when they could affect the answer
- avoid turning individual ingredient research into proof about a finished shampoo
- distinguish cosmetic hair effects from medical treatment
- describe uncertainty when reliable evidence is limited
- avoid invented personal experience
- avoid unsupported professional or medical claims
- give readers realistic expectations rather than exaggerated promises
Authors should not write that they personally tested a shampoo, worked with clients, conducted salon trials, consulted a dermatologist or used a product for a specific period unless that experience is genuinely documented.
This restriction is intentional. A useful article does not need a fictional first-person story to sound credible.
Accuracy and Source Standards
The byline does not determine whether information is true. Sources do.
For product-specific articles, AGoodShampoo generally starts with official manufacturer information, including current product pages, ingredient lists, instructions and FAQs.
Scientific and medical-adjacent claims may require stronger supporting sources such as peer-reviewed research, PubMed or NCBI-indexed literature, recognized dermatology organizations, regulatory authorities or established ingredient-safety resources.
Consumer reviews may help identify patterns in reported experience, but they are not treated as scientific evidence.
AGoodShampoo also separates several different kinds of information:
Verified product facts come from appropriate current product information.
Manufacturer claims remain manufacturer claims unless stronger independent evidence supports them.
Ingredient-based interpretation explains what a formulation may reasonably be expected to do without presenting that interpretation as clinical proof.
Independent evidence comes from relevant scientific, medical or regulatory sources.
Editorial judgment is the conclusion reached after considering the available facts, evidence, limitations and likely suitability.
These distinctions apply to every author on the site.
Updates and Corrections
Author bylines do not make an article permanent.
Hair products are regularly reformulated. Ingredient lists change, instructions are revised, product ranges disappear and scientific understanding develops.
AGoodShampoo may review or update an article when:
- a manufacturer changes a formula
- an ingredient list changes materially
- a regional formulation difference becomes relevant
- new reliable evidence affects the article’s interpretation
- an unsupported statement is discovered
- product instructions change
- a factual error is reported
Review dates help show when an article was most recently checked.
If a correction affects a material factual claim, the goal is to fix the information rather than defend an older version simply because it has already been published.
Readers can find more detail in the Editorial Policy and Corrections Policy.
Contact the Editorial Team
Readers, brands, researchers and professionals are welcome to report factual problems in AGoodShampoo content.
Useful correction requests include the article URL, the statement in question and, where possible, a current manufacturer page, ingredient list, regulatory source, research paper or other material that supports the correction.
A request from a brand does not automatically result in an editorial change. The information is reviewed against the strongest available source.
You can contact AGoodShampoo through the Contact page if you want to:
- report an incorrect ingredient list
- point out a formula change
- challenge a factual statement
- identify outdated product information
- clarify a certification or manufacturer claim
- report an author-attribution problem
Readers should expect AGoodShampoo authors to stay within the limits of what can actually be supported.
The name attached to an article matters less than the process behind it: accurate sourcing, transparent limitations, careful interpretation and a clear distinction between what a product label says and what the available evidence actually establishes.
