Our Methodology

Every product on rx-hairloss is evaluated against the same set of criteria. We do not rank products we would not personally recommend to a family member.

Our ranking criteria, in priority order:

1. Clinical efficacy evidence — are there peer-reviewed randomized controlled trials? FDA approval? What does the evidence actually show, and at what confidence level?
2. Safety profile — what are the known side effects, how common are they, and are they reversible? We do not minimize side effects to make products look better.
3. Value for money — is the price justified by the evidence? If a generic product has identical active ingredients to a brand-name product, we say so explicitly (see: Kirkland Minoxidil vs. Rogaine).
4. Ease of use and adherence — the best treatment is the one someone will actually use consistently. We consider formulation, application method, and real-world compliance data.
5. Real-world outcomes — verified user reviews, community discussion (Reddit, dermatology forums), and where possible, our own testing experience.

We update rankings when new evidence emerges, when product formulations change, or when pricing shifts meaningfully. Every article displays its last updated date.

All content on rx-hairloss is written with accuracy as the primary objective. Claims are linked to primary sources — clinical trials, FDA approval documents, and peer-reviewed reviews — not secondary coverage or marketing materials.

We are currently recruiting a board-certified dermatologist for our medical advisory board. Until that process is complete, articles are reviewed internally against primary literature. Articles that are currently pending formal medical review are noted as such.

What we do not do: publish claims without sourcing them, overstate the evidence for products we earn commissions from, or suppress negative findings about products in our rankings.

If you are a board-certified dermatologist interested in advisory board participation, contact us via the email in our footer.

We never accept payment to rank a product higher. No partner can purchase a favorable review, a top ranking, or removal of critical content from our site.

Our commission rates do not influence our rankings. When the cheapest option is also the best option, we say so — we earn a 4% Amazon commission on Kirkland Minoxidil and prominently recommend it over Rogaine because the evidence supports it, even though we would earn more by pushing the higher-priced brand.

When products have genuine downsides — like finasteride's real side effect profile, or Hims being more expensive than Keeps for equivalent medications — we state them plainly, even when those products are in our rankings.

If we have an affiliate relationship with a product, it is disclosed on the page where that product appears. Commission disclosures appear below every affiliate link button in the format: “We earn [amount] if you sign up.”

This site exists because there is a gap in the market for evidence-based, transparent affiliate content in the hair loss category. We think the approach outlined here — show your evidence, show what you earn, never let those two things mix — is the right one. If you believe we have fallen short of it, contact us.
