The Research Comes First. The Formula Follows.
Hair thinning rarely has a single cause. DHT accumulation, scalp inflammation, oxidative stress, and impaired nutrient delivery typically operate simultaneously. Every active in the KilgourMD System was selected because independent studies had already demonstrated a measurable effect on a specific mechanism.
01
Identify the Root Cause
A 2020 study published in PNAS found that young, healthy follicles stopped growing when placed into aged scalp tissue, while aged follicles resumed growth when supported by a healthy environment. The follicle's behaviour is determined by the tissue surrounding it, not by its own biology alone.
Improving the scalp itself, its inflammatory state, antioxidant capacity, and vascular supply, is the prerequisite for everything that follows.
02
Select Ingredients with Published Evidence
Each active was selected based on pre-existing independent research: peer-reviewed mechanistic data and, where available, controlled clinical measurements of actual outcomes including hair counts, shedding rates, and growth phase duration.
Most "clinically proven" claims in hair care derive from consumer satisfaction surveys. A participant reporting that their hair "feels thicker" is a perception, not a measurement. KilgourMD uses actives where the evidence involves objective assessment by trained clinicians.
03
Deliver Actives Where They Work
An active that never reaches its target is clinically inert. Most topical serums deposit actives at the surface of the stratum corneum and rely on passive diffusion to carry them deeper, a process that rarely produces meaningful concentrations at follicle depth.
KilgourMD uses a liposomal delivery system to address this. Liposomes are phospholipid vesicles with a membrane structurally compatible with human cell membranes, allowing them to fuse with the epidermal barrier and transport actives into the dermis where follicles are anchored.
04
Validate with an Independent Clinical Trial
The KilgourMD System was evaluated in a 4-month independent clinical trial of 43 women with clinician-confirmed diffuse hair thinning. A board-certified dermatologist assessed each participant at four timepoints using standardised combing tests, trichogram wash tests, and high-resolution scalp imaging.
Shedding reduced by 33.8% at Week 6, 51% at Month 3, and 60.3% by Day 120. Each checkpoint showed improvement over the last.
From the Surface
to the Follicle
Most topical serums never reach the follicle. KilgourMD uses a liposomal delivery system to change that.
The outermost layer of scalp skin acts as a selective barrier. Most topical serums deposit their actives here and are removed with the next wash.
Liposomes fuse with the skin's lipid matrix, carrying actives through the barrier rather than sitting on top.
Where follicles are anchored and dermal papilla cells reside. Reaching this layer is what separates a topical treatment from a cosmetic.
Where the mechanisms become possible. Actives suppress DHT, reduce inflammation, improve nutrient delivery, and extend the growth phase.
Where Mother Nature Meets Science.
Re-Inventing Your Scalp Health Journey.
The research behind every formula — explained simply, backed by independent science.
SCALP HEALTH
Your Scalp Is the Soil
A 2020 study published in PNAS found that even young, healthy hair follicles stopped growing when placed into aged skin — while aged follicles could regrow when supported by a healthy scalp environment. In other words, your scalp is the soil and your hair follicles are the seeds.
Without fertile soil, even the best seeds can't thrive. This research is why caring for the scalp itself — not just the strand — is essential to unlocking fuller, stronger hair.
OXIDATIVE STRESS
What Pollution And Stress Do To Your Scalp
As we age, external forces accelerate hair thinning the same way they accelerate skin aging. Pollution, UV exposure, smoking, and daily stress all trigger a buildup of free radicals — unstable molecules that damage DNA and proteins in the scalp.
This process, known as oxidative stress, weakens the scalp environment and compromises its ability to support healthy growth. That's why KilgourMD serums are enriched with antioxidants, helping defend the scalp against these aggressors and preserving its ability to grow healthy hair.
INFLAMMAGING
The Hidden Driver Of Scalp Aging
Another hidden driver of scalp aging is a process called inflammaging — chronic, low-level inflammation that builds up over time. Dandruff, harsh hair care products, and other irritants can fuel this ongoing inflammation, further damaging scalp cells and accelerating hair thinning.
By calming inflammation and restoring balance to the scalp, we can help slow down this age-related process and create the ideal environment for thicker, healthier hair to flourish. KilgourMD formulas are designed to actively soothe the scalp, reduce inflammation, and restore a healthy foundation for long-term hair growth.
The Science, Ingredient by Ingredient
Each active in the KilgourMD System has been studied independently — here's what the research shows for Redensyl®.

A 200% Increase in
Follicle Thickness
stimulate + reactivate
Redensyl® works by reactivating dormant hair follicle stem cells, helping them re-enter their active growth phase. In laboratory studies, treated follicles showed a 200% increase in thickness compared to untreated follicles — supporting hair that looks fuller and more vibrant, particularly in areas of visible thinning.

Reduces Inflammation by 48%. Increases Density by 79%.
strengthen + calm
Capixyl® combines red clover extract with a biomimetic peptide to address two causes of thinning at once — calming scalp inflammation while suppressing DHT at the follicle. In a four-month clinical study, it outperformed the leading alternative by 81%, with no known side effects.
