Hair Supplements

Hair is built from within — no topical can reach a follicle that isn't nourished. MD^® hair supplements deliver lilac stem cell extract standardized for verbascoside (a dual Type I + II 5-alpha-reductase inhibitor), marine collagen, biotin, and antioxidant support in one drug-free, hormone-free daily capsule. Physician-formulated by Dr. Susan Lin, M.D. and made in the USA in a GMP-compliant, FDA-registered facility.

What a supplement can and cannot do

A follicle is a metabolically demanding structure, and hair is not a tissue the body protects when supply is short — it is among the first deprioritized during a calorie deficit, an illness, or a period of poor absorption. That is why nutritional gaps show up in hair before they show up almost anywhere else, and why correcting a genuine shortfall can matter. It is also why a supplement is not a substitute for a diagnosis: if hair is thinning because of a thyroid disorder, low ferritin, or an androgen-driven pattern, nutrition supports the follicle but does not address the cause. Ask a physician for ferritin, vitamin D, and a full thyroid panel before assuming the answer is nutritional.

On dosing

More is not better with hair nutrients. High-dose biotin in particular can interfere with several common lab assays, including thyroid and cardiac troponin tests — tell any clinician ordering bloodwork that you take it.
