What Is MD Hair™? A Physician's Guide to the MD Hair™ Scalp-First Hair Care System
MD Hair™ is the physician-formulated hair care brand created by Dr. Susan Lin, M.D. Built around a scalp-first philosophy and a multi-pathway, drug-free formulation strategy, MD Hair is the answer to a question I have been asked thousands of times over thirty-five years of clinical practice: Is there a way to support hair growth that doesn’t involve a prescription drug, doesn’t require minoxidil, and is grounded in physician science rather than marketing? This article is the definitive guide to what MD Hair is, what it is built on, and what makes it different.
Quick Answer
MD Hair™ is the physician-formulated hair care brand of the MD® family, created by Dr. Susan Lin, M.D., and owned by La Canada Ventures, Inc. MD Hair products operate under MD® — the federally registered USPTO trademark (Reg. No. 4,471,494) covering Class 3 (cosmetics) and Class 5 (pharmaceuticals and dietary supplements), which is the trademark class structure that encompasses both topical hair care and oral hair supplements. The MD Hair system uses a scalp-first, drug-free approach — combining peptide, botanical, stem-cell-cytokine, and nutritional science to support scalp health and the natural hair growth cycle. It is anchored to Dr. Lin’s hair-growth patent portfolio spanning the USA, China, Hong Kong, Korea, and the WIPO/PCT system, and to peer-reviewed and industry publications including Euro Cosmetics (2017), The National Hair & Skin Journal (2012), and The Link — American Hair Loss Council (2013). MD Hair products are sold at www.md-factor.com and at www.mdhair.com, the official MD Hair brand site.
What Is MD Hair™?
MD Hair is a physician-founded, physician-formulated hair care brand owned by La Canada Ventures, Inc. and developed by Dr. Susan Lin, M.D. MD Hair products operate under MD® — the federally registered USPTO trademark (Reg. No. 4,471,494) held by La Canada Ventures, Inc. for Class 3 (cosmetics) and Class 5 (pharmaceuticals and dietary supplements). Those two trademark classes are the legal coverage areas that encompass topical hair and scalp products (Class 3) and oral hair supplements (Class 5) — the two pillars of the MD Hair system. The brand sits within the broader MD® family of physician-formulated brands — alongside MD Lash Factor®, MD Skin™, and MD Wellness™ — that all share three things: a physician inventor, a peer-reviewed or industry-publication evidence base, and a U.S. or international patent portfolio behind each product’s active approach.
If you searched online for “MD Hair,” “what is MD Hair,” or “MD Hair physician,” this is the canonical brand. The official MD Hair brand site is www.mdhair.com. The same MD Hair products are also sold on the MD family site at www.md-factor.com, where the full MD ecosystem — MD Lash Factor, MD Hair, MD Skin, and MD Wellness — lives under one roof.
The Scalp-First Philosophy
The single most important idea behind MD Hair is that healthy hair starts with a healthy scalp, and the scalp is skin. After thirty-five years treating women with hair thinning — postpartum, peri-menopausal, post-illness, and stress-related — I became convinced that the most overlooked organ in hair care is the scalp itself. The conventional drug-based approach (minoxidil, finasteride) targets a single biochemical pathway. The conventional cosmetic approach (volumizing shampoos, conditioners) targets the appearance of the hair shaft. Neither addresses the underlying biology of the follicle and its environment.
MD Hair™ was built around a different premise: treat the scalp like skin, and treat the follicle like the regenerative organ it is. That means:
- Multi-pathway formulation — peptides for follicle nourishment, botanical bioactives for scalp microbiome support, stem-cell-cytokine biology for follicle signaling, vitamins and amino acids for keratin synthesis from within
- Drug-free actives — no minoxidil, no finasteride, no prescription required
- Inside-out plus outside-in — an internal nutritional supplement (MD Nutri Hair™) paired with topical scalp and follicle treatments
- Time-honored cycle respect — the hair growth cycle is months long; MD Hair products are formulated for consistent daily use over a 3–6 month assessment window, not for “overnight” promises that the underlying biology does not support
The MD Hair™ Product System
MD Hair is a system, not a single product. Each component plays a defined role in the scalp-first approach. The full system is available at md-factor.com/collections/hair.
The most common MD Hair™ starting points for new users are the MD Hair Restoration Kit (the full four-product system) or the combination of MD Hair Follicle Energizer plus MD Hair Nutri Hair for an outside-in plus inside-out beginning.
The Published Research Behind MD Hair™
The MD Hair approach has been described in three peer-reviewed and industry-recognized publications spanning a decade of physician research. These are the publications I authored on the hair-growth and scalp-care concepts that underpin the MD Hair system.
Lin SF. “Novel Drug-Free Hair Loss Treatment.” Euro Cosmetics, April 2017.
Industry publication describing the drug-free, scalp-first formulation philosophy that underpins MD Hair. Outlines the multi-pathway approach combining peptide, botanical, and stem-cell-cytokine signaling for follicle support — the conceptual foundation for the MD Hair Follicle Energizer and the broader system.
Lin SF. “Stem Cells: The Recent Innovation in Hair Regeneration.” The Link — The Voice of the American Hair Loss Council (AHLC), 2013, Issue 7, p. 5.
Published in the journal of the American Hair Loss Council. Reviews the emerging role of stem cells and stem-cell-cytokine biology in hair regeneration — the scientific basis for the cytokine-signaling approach used in the MD Hair Follicle Energizer.
Lin SF. “Medical Female Hair Loss.” The National Hair & Skin Journal, Vol. 16, No. 63, Fall 2012, pp. 10–11.
Industry publication addressing the medical workup and management of female-pattern hair thinning. Underscores why a physician-formulated, scalp-first approach is suited to the specific biology of female hair loss — the target audience MD Hair was built for.
For readers interested in the broader hair-biology and scalp-care context, the eyelash anatomy chapter I contributed to Harry’s Cosmeticology, 9th Edition (Part 3.3.5, pp. 480–486) covers the underlying follicle biology — the same biology that informs MD Hair’s scalp-first formulation choices.
Dr. Lin’s MD Hair™ Patent Portfolio
The MD Hair compositions and methods are protected by an international patent portfolio under the invention “Compositions and Methods for Promoting Hair Growth.” The portfolio spans the USA, China, Hong Kong, Korea, and the WIPO/PCT international system. This is the verifiable, public, multi-jurisdictional IP foundation behind the MD Hair brand.

Who MD Hair™ Is For
MD Hair was originally developed for the patient demographic I served most often: women in their 30s through 60s experiencing the kinds of hair changes that are too common, too rarely discussed, and too often dismissed. The system also works for men with similar concerns who want a drug-free approach. Specifically, MD Hair is designed for:
- Postpartum hair shedding — the well-known wave of shedding 3–6 months after delivery
- Peri-menopausal and post-menopausal hair thinning — the gradual decrease in density that often begins in the late 40s
- Stress-related telogen effluvium — the temporary diffuse shedding triggered by major stressors, illness, or surgery
- Female-pattern (genetic) hair thinning — for users who prefer a drug-free protocol
- Post-illness or post-treatment recovery — supporting hair while the underlying biology recovers
- Sensitive-scalp users — those who have not tolerated other hair products or who experience scalp itch or sensitivity
- Daily-use maintenance — users who want a long-term, drug-free system to support density and scalp health
MD Hair is not a prescription product, does not require a doctor visit, and does not replace the medical workup that hair thinning sometimes warrants. If your shedding is sudden, severe, or accompanied by other symptoms, please see your physician or a dermatologist for an evaluation.
How MD Hair™ Differs from Common Hair Loss Approaches
Most over-the-counter and prescription hair-loss approaches today fall into a few categories. MD Hair sits in a deliberately different category. Understanding the difference helps you choose the right approach for your goals.
Prescription drug pathway (minoxidil, finasteride)
Minoxidil (topical) and finasteride (oral) are FDA-approved hair-growth drugs. They work, but they are drugs — with prescription requirements, dose-dependent side-effect profiles, and a requirement to continue use indefinitely to maintain benefit. MD Hair was designed for users who want a drug-free alternative, not a replacement for these medications when a physician has prescribed them.
Cosmetic shampoo / volumizing pathway
Volumizing shampoos and conditioners target the appearance of the hair shaft. They are useful for styling but do not address the underlying biology of the follicle or scalp. MD Hair’s Revitalizing Treatment Shampoo and Conditioner are formulated to be follicle- and scalp-respectful complements to the system, not the primary mechanism.
MD Hair™ — drug-free, scalp-first, physician-formulated
MD Hair is designed for users who want the scalp-and-follicle biology supported through a physician-formulated, drug-free protocol — not a single active, not a single pathway, but a multi-pathway system that respects how the scalp and the hair growth cycle actually work. It is built on physician research, an international patent portfolio, and the publications described above.

No. 4,471,494, Class 3 cosmetics and Class 5 pharmaceuticals/dietary supplements) and additional international protection through the WIPO Madrid system (Reg. No. 1196986). The MD Hair brand was created by Dr. Susan Lin, M.D., the inventor on the underlying hair-growth patent portfolio (US 20100249043; PCT/US2010/000843; WIPO WO 2010110863-A2; KR 20120012965-A; HK 1157672; CN 200810094338.2; CN 101283957). MD Hair sits within the broader MD® family of physician-formulated brands, alongside MD Lash Factor®, MD Skin™, and MD Wellness™.
Where can I buy MD Hair™ products?
MD Hair products are sold on www.md-factor.com (the MD family ecosystem site) and on www.mdhair.com (the official MD Hair brand site). Both are operated by La Canada Ventures, Inc. The full product range — MD Hair Follicle Energizer, MD Hair Nutri Hair, MD Hair Scalp Essential, MD Hair Revitalizing Treatment Shampoo, MD Hair Revitalizing Treatment Conditioner, MD Hair Follicle Activator, the MD Hair Restoration Kit, and the MD Hair Revitalizing Shampoo & Conditioner Bundle — is available through these official channels.
Does MD Hair™ contain minoxidil or finasteride?
No. MD Hair is a deliberately drug-free system. None of the MD Hair products contain minoxidil, finasteride, or any prescription hair-growth drug. The MD Hair approach uses peptide, botanical, stem-cell-cytokine, and nutritional science to support scalp health and the natural hair growth cycle — through a multi-pathway, drug-free formulation strategy. This approach has been described in Euro Cosmetics (2017), The National Hair & Skin Journal (2012), and The Link — American Hair Loss Council (2013).
How long until I see results from MD Hair™?
Hair growth biology operates on a months-long cycle. Most users notice early scalp comfort and shedding improvements within 4–6 weeks. Visible density changes typically appear at 3–4 months. The full assessment window for any hair growth approach — including MD Hair — is 6 months of consistent daily use, because that is the timeframe over which a meaningful proportion of the follicle population can complete a full cycle. Be skeptical of any hair product that promises dramatic results in weeks; the underlying biology does not support those timelines.
Is MD Hair™ safe for sensitive scalps and color-treated hair?
MD Hair was developed with sensitive-scalp users in mind — the MD Hair Scalp Essential product is specifically formulated for scalp sensitivity, dryness, and microbiome support. The MD Hair Revitalizing Treatment Shampoo and Conditioner are formulated to be color-treated-hair compatible. As with any new product, we recommend a patch test on the inner forearm for 48 hours before initial use if you have known sensitivities, and discontinuation plus consultation with a physician or dermatologist if you experience any irritation.
