Who formulates MD Hair products?

Dr. Susan Lin, M.D., a practising physician who put her own name on the label rather than licensing it — which is the distinction the article is built around.

What patent sits behind MD®?

U.S. Patent 8,206,695, on which Dr. Lin is the named inventor, alongside published applications covering hair growth compositions.

What should physician-formulated actually mean?

That a clinician made the formulation decisions and is accountable for them — not that a doctor was paid to appear on the packaging.

The MD® Story: How a Practising Physician Built a Hair Line

Most brands license a doctor's name — I put my own on the label.

That single sentence is the shortest honest history of MD® I can give you. Everything else in this article — the patents, the certifications, the two decades of formulation work — flows from the decision behind it: that if I was going to stand behind a product, I would stand behind it with my own name, my own medical license, and my own reputation, in a way I could never walk away from.

This is the story of how a practicing physician ended up building a formulation company, what I believe “physician-formulated” is supposed to mean, and why — nearly two decades in — I still read every ingredient deck myself.

From the Exam Room to the Formulation Bench

I did not set out to found a beauty company. I trained at Boston University School of Medicine in its accelerated B.A./M.D. program, as an NIH Scholarship recipient, and built a career as a board-certified physician in Obstetrics & Gynecology — later adding board certification in Anti-Aging Medicine (A4M). My world was the exam room.

But the exam room is exactly where this company started. Year after year, women sat across from me and described the same cluster of concerns their medical care had no good answer for: lashes that had thinned with age or after illness. Hair that was shedding with hormonal transitions — postpartum, perimenopause, thyroid disease. And when I surveyed what the market offered them, I found two unsatisfying categories. On one side, pharmaceutical options that were genuinely effective for some women but carried side-effect profiles, contraindications, and commitments that many of my patients could not or would not accept. On the other, a cosmetics aisle full of beautiful packaging, borrowed credibility, and formulas no physician had meaningfully touched.

I kept waiting for someone to build the third option: cosmetic formulas designed with a physician's discipline — mechanism-first, suitability-first, honestly positioned. Eventually I stopped waiting.

In 2007, I formulated the first MD® product, a lash serum — because lashes were where I saw the clearest gap between what women wanted and what they were being offered. In 2008, I expanded into hair, which had always been the larger and more emotionally weighted problem in my practice. From those two starting points grew the MD® family of products, formulated under my direction ever since, through La Cañada Ventures, Inc., based in San Mateo, California.

Putting My Own Name on the Label

Here is something most consumers never see: the standard playbook for launching a “doctor brand” does not require the doctor to do much. A company develops a formula, then licenses a physician's name and photograph to put on the box. The doctor may review a summary. The doctor rarely chooses the ingredients, sets the concentrations, or reviews the safety data. The arrangement is an endorsement contract wearing a lab coat.

I chose the opposite structure. MD® is not a name I rent out — it is the company I own and the formulas I direct. That distinction changes behavior in ways that compound over twenty years:

I answer for suitability. When you are the licensing doctor, a bad reaction is the brand's problem. When you are the founder-formulator, it is your problem — so you formulate from the start for the sensitive user, the postpartum user, the user already juggling other treatments.
I answer for claims. My name is on the label, and my medical reputation travels with every sentence of marketing copy. That is a powerful internal regulator. It is why you will never see MD® describe a cosmetic product as “FDA approved” — cosmetics are not FDA-approved, and any brand telling you otherwise is telling you something important about itself (FDA, on cosmetics authority). Our products are made in FDA-registered, GMP-compliant facilities in the USA; that is a statement about manufacturing standards, and it is the accurate one.
I answer over time. Endorsement deals end. Ownership doesn't. The formulas have been refined continuously since 2007–2008 because the same physician has been looking at them the whole time.

The Formulation Philosophy: Suitability First

Two decades of formulation have settled into a philosophy with three commitments.

First, suitability before potency. The most effective ingredient in the world is useless to the woman who cannot tolerate it or should not be exposed to it. Every MD HAIR formula is drug-free and hormone-free by design — built for the widest population of women I saw in practice, including those navigating hormonal transitions who are the least served by drug-based options and often the most wary of adding anything systemic. Our formulas are also designed to be compatible with a physician-supervised regimen: they work with or without minoxidil, so a woman never has to choose between her doctor's plan and her hair care routine.

Second, mechanism-driven ingredient selection. I choose botanicals and peptides the way I was trained to evaluate any intervention: start from the biology. If an ingredient earns a place in an MD® formula, it is because there is a plausible, literature-supported mechanism relevant to the follicle and scalp environment — and because it can be delivered at a meaningful concentration in a cosmetic format. Ingredient lists assembled for marketing poetry — a botanical garden at trace concentrations — are the industry norm. They are not our norm.

Third, substantiation on file. Cosmetic marketing is governed by a simple principle I take seriously: say only what you can support, and keep the support. For the MD® family, that means safety and claim substantiation documentation maintained on file, honest positioning — these are cosmetic products, not treatments for disease — and a standing commitment on every page we publish: individual results vary, and your own physician should remain at the center of any hair loss evaluation.

The Patent Behind MD®

There is a simple test of whether a formulation is original work or a repackaged commodity: ask what is patented.

I am the named inventor on U.S. Patent No. 8,206,695, granted on the lash formulation that started the company. I will not pretend a patent number is a substitute for results — it isn't, and patents are grants of intellectual property, not endorsements of efficacy. Nor does it extend to everything we make: our hair products are not sold on the strength of that patent, and I won't imply otherwise. But a patent with the founder's name in the inventor field tells you something that no amount of advertising can: the formulation work happened here. It was novel enough to protect, and the person whose name is on the label is the person listed as inventor.

A Global Journey, Anchored in San Mateo

What began as one physician's answer to her own patients has traveled further than I imagined in 2007. MD® products are now used by customers in many countries — a humbling thing to say about formulas that started as a response to conversations in a single practice.

Through all of it, the company has stayed what it was on day one: La Cañada Ventures, Inc., a physician-owned business headquartered in San Mateo, California. We are an NMSDC-certified Minority Business Enterprise (MBE), a WBENC-certified Women's Business Enterprise (WBE), and a Veteran-Owned Small Business. Our products are made in the USA, in FDA-registered, GMP-compliant facilities. These certifications are not wall decorations to me. Each one is an external audit of who actually owns and runs this company — and in an industry where brand stories are often manufactured alongside the product, third-party verification of the real story matters.

What “Physician-Formulated” Should Mean

Walk any beauty aisle and you will see the phrase everywhere. It has no regulated definition, which means the burden falls on you, the reader, to interrogate it. After twenty years on the inside of this industry, here is the standard I would hold any brand to — including mine:

Named accountability. Which physician? Is she identified, credentialed, and publicly attached to the formulas — or is “physician-formulated” a phrase floating free of any actual person?
Ownership, not endorsement. Does the physician own the formulas and answer for them over time, or was a name licensed for a campaign?
Inventorship. If the formulation is genuinely original, where is the intellectual property, and whose name is on it?
Honest boundaries. Does the brand say plainly what a cosmetic product is and is not? Does it tell you to work with your own doctor — or position itself as a replacement for one?

MD® exists because I believed a brand could meet all four standards. You can read my full background at my physician page — and I encourage you to apply the same four questions to us that I have just taught you to ask of everyone else.

The Bottom Line

The MD® story is not complicated. In 2007, a practicing OB/GYN got tired of having nothing honest to hand her patients and formulated a lash serum. In 2008, she followed the bigger problem to hair. She put her own name on the label instead of licensing it, patented that original lash formulation with her own name in the inventor field, kept the formulas drug-free and hormone-free so they could serve the women pharmaceutical options left behind, and built a certified, physician-owned American company around them. Two decades later, the products have traveled around the world — but the standard has never moved: formulate as if every customer were sitting in your exam room. Because when your name is on the label, she is.

Dr. Susan Lin's Clinical Perspective

“In 35 years of medicine, I've learned hair loss is never vanity — it's identity. That conviction is the entire reason MD® exists. A woman losing her hair is not a 'consumer segment' to me; she is the patient I sat across from for decades, and she deserves the same discipline in a cosmetic formula that she gets in a clinical decision: a plausible mechanism, suitability for her actual circumstances, substantiation on file, and no promises the evidence cannot carry. 'Physician-formulated' should mean a physician is accountable — by name, over time, for everything on and in the bottle. Anything less is marketing.”

— Dr. Susan Lin, MD, Physician Formulator, MD HAIR

Formulation Spotlight: The Difference Between a Name on the Box and a Physician Behind It

Here is how the two models actually work, side by side. In the licensing model, a manufacturer develops a formula — often from a contract lab's existing library — then pays a physician for the right to print her name and photo on the packaging. The physician's involvement can be as thin as a single review meeting; her incentive is the licensing fee, and her exposure ends when the contract does. In the founder-formulator model, the physician specifies the mechanism she is targeting, selects the actives, sets the concentrations, reviews the safety data, and owns the outcome — legally, financially, and reputationally — for as long as the company exists. The consumer-facing packaging of the two models can look identical. The accountability structures could not be more different. The fastest way to tell them apart: look for a named physician, look for inventorship on the intellectual property, and look at whether the same doctor has been attached to the same formulas for years. A rented name migrates. A founder stays.

MD HAIR Product Recommendation

MD® Hair Restoration Kit — The Complete 3-Step Protocol

If two decades of formulation philosophy had to be expressed in a single product, it would be the MD® Hair Restoration Kit: Scalp Essential + Follicle Energizer + Nutri Hair — scalp, follicle, and internal nutrition together. It is the complete protocol as I designed it to be used: prepare the scalp environment, deliver mechanism-driven botanical and peptide support to the follicle, and address nutritional foundations from within — drug-free, hormone-free, and fully compatible with a regimen that includes minoxidil or one that deliberately avoids it. As with everything we make, individual results vary — give any regimen a consistent 3–6 months, photograph your progress, and keep your own physician in the loop.
