When I saw my mother struggling with hair thinning during menopause, I knew I had to do something. As a board-certified dermatologist, I formulated KilgourMD for her - the first patent-pending scalp health innovation in 75 years - combining natural botanicals with clinically proven results.

The Science

The KilgourMD Dual Action System is backed by over 40 published clinical and laboratory studies – making it one of the most scientifically-validated natural formula on the market.

Clinical Results

The KilgourMD system combines Redensyl®, Capixyl®, and Procapil®—ingredients that have been evaluated in a published, peer-reviewed clinical trial reporting improvements across multiple hair-related outcomes, including physician assessments. In our 2026 trial, the serums were well tolerated, with no adverse effects reported.

How to Use
  1. Start with a clean scalp
    Apply to a dry or lightly damp scalp.
  2. One dropper daily
    Your dropper dispenses a full 1 mL in a single step. Press once, then release slowly to let the dropper fill completely.
  3. Apply, massage, and leave in
    Part the hair and apply directly to thinning or shedding areas. Massage gently for 30–60 seconds. Do not rinse.
  4. Stay consistent
    Use daily. If you miss a day, simply resume—no need to double up.

ABOUT OUR FOUNDER
A Personal Note from James Kilgour, MD

I created KilgourMD for one person: my mum.

After menopause, she lost most of her hair. I watched this vibrant woman stop going out, stop taking photos, stop feeling like herself. As a board-certified dermatologist, we had access to everything - but nothing worked without terrible side effects.

Today, my mum has thicker hair at 68 than she did at 50. It started with her, then her friends, and now over 200,000 women have experienced the same transformation. This was never about creating another hair product. It was about giving my mum her confidence back.

The KilgourMD Dual Action System is backed by over 40 published clinical and laboratory studies.

01 Menopausal Hair Thinning

During menopause, your scalp ages up to 10× faster than your facial skin. By age 50, your scalp can biologically resemble that of a 90-year-old. This accelerated aging is why many women lose nearly half their hair before they even notice the change. The good news? Breakthrough research shows that restoring a youthful scalp environment can reactivate growth — helping you grow fuller, healthier hair again, no matter your genetics or past treatment failures.

02 GLP-1 Thinning

The KilgourMD system is designed to address the metabolic shock and scalp aging that rapid weight loss can cause, regardless of GLP-1 treatment.

03 Peri-Partum Thinning

Hormonal disruptions are the primary cause of hair changes for new moms, influencing everything from hair density and strength to hydration and shine.

The postpartum hair disruption process is mainly driven by three interrelated factors: the DHT follicle killer, oxidative stress, and inflammaging. Their combined effects hinder the scalp’s ability to support healthy follicles, causing increased shedding, thinning, brittleness, and slowed growth—issues that most women begin to notice during maternity.
