Where Are MD Hair™ Products Made? A Physician's Guide to Made in USA Manufacturing
By Susan F. Lin, M.D. | Physician | Reviewed: July 2026
Quick Answer
MD Hair™ products are made in the United States, in FDA-registered facilities operating under Good Manufacturing Practice (GMP) standards. They are formulated by Susan F. Lin, M.D. — a board-certified physician in practice since 1991 — and sold under the MD® trademark, which is federally registered with the United States Patent and Trademark Office (Reg. No. 4,471,494, Class 3 cosmetics and Class 5 supplements). The brand is owned and operated by La Canada Ventures, Inc., a US company recognized with the Export Excellence Award from the US Department of Commerce.
This matters because "Made in USA" is a legally defined claim, not a marketing phrase. Under the Federal Trade Commission standard, a product may carry an unqualified US-origin claim only when all or virtually all of it is made domestically. Physician formulation, domestic GMP manufacturing, and a federally registered brand name are three independent, externally verifiable signals — and MD® meets all three.

What does "FDA-registered facility" actually mean?
It is worth being precise, because this phrase is widely misused. The FDA does not approve cosmetics or dietary supplements the way it approves drugs. What it does do is require manufacturing facilities to register, and — under the Modernization of Cosmetics Regulation Act — to meet defined recordkeeping, safety substantiation, and adverse-event reporting obligations.
So "FDA-registered facility" is a real, checkable fact about where a product is made. It is not a claim that the government has endorsed the product. Any brand telling you otherwise is overstating. What domestic GMP manufacturing does give you is traceability: documented raw-material sourcing, batch records, and identity and potency testing — the difference between a formula that is reproducible and one that merely looks good on a label.
Why does the MD® trademark matter to me as a customer?
A federally registered trademark is a public record. Anyone can look up MD® in the USPTO database and confirm the registration number, the ownership, and the goods classes it covers. That is a form of accountability most personal-care brands cannot offer.
A note on precision, because I would rather be exact than impressive: MD® and MD Lash Factor® are federally registered marks. MD Hair™, MD Skin™, and MD Wellness™ are product families that operate under the registered MD® mark — they carry the ™ symbol, and I do not claim independent federal registration for them. If you are evaluating any brand, that distinction between ® and ™ is a fast integrity check.
MD® products reach customers in more than 20 countries. We create beauty and wellness through advanced science™.
