Systems & Kits
Hair loss rarely has one cause, and single products rarely finish the job. MD® systems combine scalp preparation, peptide follicle treatment, internal nutrition, and peptide cleansing into complete protocols — each step formulated by Dr. Susan Lin, M.D. to reinforce the others. Every system is drug-free, saves versus buying separately, and works with or without minoxidil or finasteride. Best results come from the most complete routine you'll actually keep.
Why the steps are sequenced
Each step prepares the one after it. Cleansing clears the follicle opening of the oil and dead skin that otherwise sit between a topical and the scalp. The leave-in serum is applied to that cleared scalp, where it can reach the follicle. The daily capsule supplies the raw material the follicle needs to act on any of it. Used out of order, or used in isolation, each step still does its own job — it simply does it with less support.
What to expect, and when
A hair follicle works on a cycle measured in months, so a realistic first review point is 90 days and a fair one is six months. That is the reasoning behind the 90-day system rather than a single bottle. Individual results vary.
