This page explains what ScalpNest verifies, what it does not verify, and how to read our product comparisons. It was rewritten in September 2026 to match how the site actually works.
How we research
Our coverage is documentation-based. We read current manufacturer pages and manuals, ingredient and specification panels, packaging information where it is publicly visible, retailer listings, and applicable regulatory or certification records. Claims that belong to a manufacturer are attributed to the manufacturer.
We do not buy, consume, wear, or lab-test the products we write about, and no page claims otherwise. If that ever changes, the page will publish a dated protocol, the sample source, the conditions, and the evidence. Earlier versions of this site described purchases and multi-week trials that did not take place; those passages were removed.
What we never publish
We do not invent prices, stock levels, discounts, certifications, laboratory results, review counts, or star ratings. Product pages carry no numerical score and publish no rating to search engines as structured data. We do not manufacture urgency or scarcity.
Medical boundary
ScalpNest is a consumer product-research site, not a medical resource. No one writing here is a physician, dermatologist, or trichologist, and nothing here is medical advice, diagnosis, or treatment. Dandruff, seborrheic dermatitis, psoriasis, and hair loss overlap in symptoms and differ in treatment. Persistent, painful, spreading, or worsening symptoms warrant a board-certified dermatologist.
Evidence language
Where we describe possible benefits we use qualified language and say where research is small or preliminary. We are especially cautious with hair-growth claims.
Independence
No brand can pay for inclusion, wording, placement, or a favourable description. Some links are affiliate links and a qualifying purchase may earn a commission at no additional cost to you; that relationship does not change what we write. See the affiliate disclosure.
Corrections
Product formulations, specifications, and availability change. If something here is out of date or wrong, send the page URL and a source through the contact page and we will correct or remove the claim.
