Healthy-looking hair starts with a calm, clean scalp. Itch, flakes, and excess oil make the scalp a poor environment for the hair you have. MD® Scalp Essential is a leave-in, zero-grease serum formulated by Dr. Susan Lin, M.D. to cleanse the look of follicles, soothe the appearance of irritation, and prep the scalp — including before and after hair-transplant procedures.
Mandelic acid exfoliates gently (a larger molecule than glycolic, so it works without the sting), caffeine refreshes the follicle environment, and lilac stem cell extract with CLA glutathione helps soothe the look of the scalp and support a balanced-feeling scalp environment behind many flaky, itchy scalps.
Evaluated at Medcin Instituto under GCP and Helsinki-compliant protocols; a 50-subject repeat-insult patch test (RIPT) graded it hypoallergenic and non-sensitizing.
Key Ingredients
Named, clinically-studied actives — not a generic conditioning blend. Rotate through each one.
A larger molecule than glycolic acid, so it exfoliates the scalp gradually and without the sting — the reason it is chosen for sensitive and post-procedure scalps.
Benefit: Clears the look of buildup and flakes without irritating a healing scalp.
Applied topically, caffeine refreshes the follicle environment and is one of the most widely studied cosmetic scalp actives.
Benefit: An energised, cleaner-feeling scalp between washes.
The same lilac-derived botanical family behind MD Nutri Hair™, here paired with CLA glutathione to soothe the look of the scalp and support a balanced-feeling environment.
Benefit: Calms the appearance of the irritation behind many flaky, itchy scalps.
MD HAIR addresses the same biology the leading hair drugs are known for — the DHT pathway, follicle signaling, and the natural cycle — with plant-derived and peptide actives instead of drugs.
How to Use
Apply to the scalp 2–3 times per week (or daily for oily scalps), massage in, leave on. No rinse, no residue — it also works as a cleaner-feeling alternative to dry shampoo.
Frequently Asked Questions
Yes — this is one of its signature uses. Mandelic acid is gentler than glycolic on healing skin, and the serum helps keep grafts' environment clean. Follow your surgeon's timeline for when to resume topicals.
No — it's a leave-in serum. Keep your normal wash routine (ideally the MD Revitalizing Treatment Shampoo) and use Scalp Essential between washes.
Yes. No minoxidil, no steroids, no hormones — safe to combine with any regimen.
Itch and flake relief typically comes in 1–2 weeks; scalp-environment benefits for the look of density build over 3–6 months.
It's Step 1 of the 3-step MD HAIR™ Restoration Kit: calm the scalp (Scalp Essential) → condition the follicles (Follicle Energizer) → nourish from within (Nutri Hair).
