In our 2026 trial, the serums were well tolerated, with no adverse effects reported.
We intentionally designed our serums to work perfectly together, as well as with your lifestyle. For optimal results though, here are some tips from us.
Why subscribe rather than one off purchase?
Hair growth is a gradual process, not an overnight fix. Because hair grows in cycles, it typically takes consistent use over several months to start seeing visible improvements. A subscription ensures you stay consistent without interruptions—so your scalp and hair follicles get the ongoing support they need for the best possible results. It also takes the guesswork out of reordering, so you never miss a day in your routine.
Isn’t it just genetics?
Genetics can play a role in hair thinning, but they’re only part of the picture. Factors like scalp health, stress, hormones, and environmental exposure can also influence how your hair looks and grows over time. With the right routine and consistent care, you can help support a healthier scalp environment and improve the appearance of fuller, stronger-looking hair—regardless of your starting point.
How is KilgourMD different from regular hair growth products? Is it worth it?
KilgourMD stands out from other brands by formulating with clinically studied ingredients like Redensyl®, Capixyl®, and Procapil® at their proven effective dosages and in higher concentrations of active ingredients overall—while many other brands include only trace amounts for label appeal rather than real results.
Does it work for all hair types?
Yes—KilgourMD is designed to support all hair types and textures. Whether your hair is straight, wavy, curly, or coily, the formulas are developed to care for the scalp and support fuller-looking, healthier hair.
Why is liposomal delivery important?
Liposomal delivery helps enhance how ingredients are applied to the scalp. These microscopic, skin-compatible carriers are designed to help ingredients spread more evenly and integrate seamlessly into your scalp care routine.
This means the formula can:
- Distribute ingredients more evenly across the scalp
- Improve the overall feel and consistency of application
- Help optimize the performance of key ingredients
By using advanced delivery technology, KilgourMD ensures each ingredient is delivered in a way that supports a well-cared-for, healthy-looking scalp—without irritation.
How long does one bottle of each serum last?
1 bottle = 1 month of usage.
What is the 90-day guarantee?
We’re confident you’ll love your results. While optimal improvements typically take 3–6 months of consistent use, many people notice early signs around 6 weeks - like reduced shedding, less scalp irritation, and a healthier-feeling scalp.
That’s why we offer a 90-day, no-questions-asked refund, backed by our full refund policy.
Refunds are subject to our full refund policy.
Is this suitable for platinum blonde or predominantly grey hair?
For very light blonde or predominantly grey hair, the L-ascorbic acid in The Prevention may cause temporary warmth or brassiness at the roots if buildup occurs. This is purely cosmetic and fades after a few washes.
To minimize this, we recommend daily rinsing or using KilgourMD Shampoo to prevent buildup. If that’s not practical, consider using The Treatment Scalp Serum on its own instead of the full bundle.
