What is the MD® Hair Care System — Complete Set?

The MD® Hair Care System — Complete Set is a physician-formulated, drug-free 2-step topical regimen developed by Dr. Susan Lin, M.D. It combines MD Follicle Activator (Step 1) and MD Follicle Energizer (Step 2) to nourish the scalp and condition hair for the appearance of fuller, thicker, healthier-looking results — without hormones or harsh chemicals.

How is the Complete Set different from the 3-step MD® Hair Care System?

The Complete Set (Follicle Activator + Follicle Energizer) is topical only — designed for users who prefer a focused two-serum routine. The 3-step MD® Hair Care System pairs MD Follicle Energizer with MD Scalp Essential (exfoliating leave-in) and MD Nutri Hair supplement (oral) for scalp care plus internal nourishment.

What does each step do?

Step 1 (MD Follicle Activator) features Acetyl Tetrapeptide-3 and Red Clover Extract to condition hair at the root, plus Niacinamide, Panthenol, and Ergothioneine to condition the scalp and help protect against oxidative stress. Step 2 (MD Follicle Energizer) uses Biotinoyl Tripeptide-1, Saw Palmetto, and marine botanicals to condition fragile-looking hair for a denser look.

How do I use the System?

Apply MD Follicle Activator to a clean, dry scalp in the morning, focusing on areas where hair looks thinner — let absorb fully. In the evening, apply MD Follicle Energizer to clean, dry scalp. Consistency matters more than timing, but daily use is essential. Designed as a 3-month supply.

Can men and women use the Complete Set?

Yes. The Complete Set is suitable for adult women and men who want fuller-looking, healthier-looking hair, including fine or thinning-looking hair. It is formulated without hormones.

How long until I see results from the Complete Set?

Hair changes gradually. With consistent daily use, many users see a difference in how full and healthy their hair looks within 3-6 months. In a 17-week independent study at Spincontrol North America, 71% of participants reported an improvement in the appearance of their hair (participant self-assessment). Individual results vary. The 3-month supply supports a full course of daily use.

Does the System contain minoxidil or finasteride?

No. Neither MD Follicle Activator nor MD Follicle Energizer contains minoxidil, finasteride, ketoconazole, or any other prescription drug. The Complete Set uses peptides, marine botanicals, and plant extracts for cosmetic scalp and hair care. MD Follicle Activator also contains dechloro ethylcloprostenolamide, a cosmetic-grade prostaglandin analogue.

Is the MD Hair formulation patented?

Yes. The MD Hair system is protected by an international patent portfolio including US Patent Application Publication 20100249043, PCT/US2010/000843, WIPO Publication WO-2010110863-A2, Korean Application KR 20120012965-A, Hong Kong Patent HK 1157672, and Chinese Patent CN 101283957.

Can I use the MD® Hair Care System — Complete Set if my hair is shedding after pregnancy, during menopause, or on Ozempic®?

Shedding after pregnancy (postpartum), around menopause, or with rapid weight loss on GLP-1 medications such as Ozempic® is common and often temporary — see your doctor to check for underlying causes. The Complete Set's two cosmetic scalp serums, MD® Follicle Activator and MD® Follicle Energizer, can be used to keep the scalp conditioned and hair looking fuller during that time. It is not a treatment for hair loss. If you are pregnant or breastfeeding, ask your physician before starting any new topical product.

Seeing Is Believing

Before use, hair can look fine, fragile, and dull — and the scalp can feel dry and unbalanced.
After consistent use of the MD® Hair Care System — Complete Set, the scalp feels refreshed and hair is better conditioned from the root.
Strands look visibly thicker, stronger, and shinier, while the scalp feels comfortable and balanced.
Over time, hair takes on a fuller look — healthier-looking, denser-looking, and more resilient to the touch. Individual results vary.
