What is MD Scalp Essential?

MD Scalp Essential is a physician-formulated, lightweight leave-in scalp serum developed by Dr. Susan Lin, M.D. It combines mandelic acid for gentle exfoliation, caffeine to refresh the scalp, and lilac stem cell extract to support scalp comfort and the appearance of fuller, healthier-looking hair.

How does MD Scalp Essential work?

Mandelic acid gently exfoliates the scalp to lift buildup, flaky skin, and product residue. Caffeine leaves the scalp feeling refreshed, and lilac stem cell extract delivers antioxidant care — together creating a clean, balanced base for stronger, healthier-looking strands.

Is MD Scalp Essential gentle enough for a sensitive scalp?

MD Scalp Essential uses mandelic acid, an exfoliating acid that is gentler than glycolic acid, in a lightweight leave-in formula. In a 50-subject repeat insult patch test, no sensitization was observed under study conditions. If you have had a recent scalp procedure or have a scalp condition, ask your physician before introducing any topical product.

How do I use MD Scalp Essential?

Apply to a clean, towel-dried scalp. Massage gently with fingertips for 30-60 seconds. The lightweight, non-greasy formula leaves zero residue or buildup. Use once daily, as described in How to Use.

What makes MD Scalp Essential different from a regular shampoo?

Shampoos rinse off in minutes. MD Scalp Essential is a leave-in treatment that stays on the scalp to continuously deliver mandelic acid, caffeine, and lilac stem cell extract throughout the day. It's a leave-in serum, not a cleanser — designed to complement your wash routine, not replace it.

Does MD Scalp Essential contain drugs or hormones?

No. MD Scalp Essential is completely drug-free and hormone-free. It does not contain minoxidil, finasteride, ketoconazole, or any pharmaceutical drug. It uses cosmetic-grade exfoliating acids and botanical actives to support scalp wellness.

How long until I see results from MD Scalp Essential?

Your scalp should feel cleaner and more comfortable within the first weeks of daily use. For hair that looks fuller, Dr. Lin recommends consistent use as part of the full MD Hair routine for 3-6 months.

Is MD Scalp Essential part of an MD Hair routine?

Yes. MD Scalp Essential is the first step of the MD Hair routine, alongside MD Follicle Energizer and MD Nutri Hair. It can also be used on its own by anyone who wants gentle scalp exfoliation and a refreshed-feeling scalp.

Multi-Layer Scalp Science for Healthier Hair Foundations

A daily leave-in serum that gently exfoliates, soothes, and refreshes the scalp — for fuller-looking, healthier-looking hair.

MD® Scalp Essential is built around the principle that fuller-looking hair starts with a healthy-looking scalp. The signature triad of Mandelic Acid (an almond-derived AHA), Lilac Stem Cell Extract, and Caffeine works together on three everyday scalp concerns: buildup, excess oil, and a dry, uncomfortable feel.

Unlike scalp products that focus on one issue, MD's formula clears excess oil and dead skin without harsh stripping, soothes the feel of a sensitive scalp, and refreshes it with antioxidant-rich ingredients. Lilac Stem Cell Extract helps the scalp look and feel less oily and more comfortable.

Ideal for oily scalps, fine or thin-looking hair, scalps that need a refresh after wigs or extensions, or anyone who wants fuller-looking hair. Drug-free, hormone-free, physician-formulated for daily use.
