"It started with finding hair everywhere except where it should be – on my head."
That's how 41-year-old Rebecca Martinez describes the morning she discovered what thyroid-induced scalp issues can do...
Rebecca's hairdresser of 12 years was the first to notice however. "She asked if I'd been stressed because my part was widening dramatically."
Within weeks, Rebecca's thick auburn hair had transformed into something she barely recognized.
Brittle strands that snapped when touched. A texture like dried straw. Visible scalp showing through what remained.
"I collected the hair from my shower drain one morning," Rebecca recalls. "It filled my entire palm. That's when I knew something was seriously wrong."
Even though it may seem dramatic, this is not out of the ordinary for many women...
"By the time most thyroid-affected women notice thinning and shedding, up to 60,000 hairs—50% of what's on your head—could already be gone," says Dr. Kilgour.
"By the time most thyroid-affected women notice thinning and shedding, up to 60,000 hairs—50% of what's on your head—could already be gone"
What Rebecca experienced is happening to millions of women. You look in the mirror one day and barely recognize your own hair.
But what if the real problem isn't what you see on your hair—but what's been happening invisibly to your scalp?
The Devastating Truth About Your Scalp
Here's what most women don't realize: your scalp ages almost 10 times faster than your facial skin when it is under pressure from thyroid imbalances.
This means you could easily have a 90-year-old scalp before you turn 60.
"This accelerated aging is precisely why you can lose half your hair before you notice anything wrong," explains Dr. Kilgour. "While you're carefully applying anti-aging creams to your face, your scalp is experiencing rapid aging that goes completely unaddressed."
Through years of research at the top universities and real-life experience as a clinician at Stanford, Dr. Kilgour identified an issue behind this accelerated aging which he calls a "Thyroscalp"—a three disruption combination affecting women with thyroid issues.
Dr. Kilgour discovered this pattern after noticing that his patients with thyroid-related hair issues all developed nearly identical scalp conditions, regardless of their medical treatment or hair care routines.
The Three Disruptions Behind ''Thyroscalp''
1. Poor Scalp Circulation
Thyroid imbalances limit blood flow to hair follicles, restricting oxygen and nutrient delivery through the bloodstream. Even if nutrients are available, they can't reach the follicles that need them.
2. Environmental Damage
Decades of UV exposure, pollution, and styling heat damage begins compounding as aging accelerates, harming the follicle environment and DNA.
3. Interrupted Growth Cycles
Your scalp can no longer maintain normal hair cycles, forcing follicles to exit the growth phase prematurely and remain stuck in shedding mode.
1. Poor Scalp Circulation
Thyroid disturbance compromises blood flow to hair follicles, limiting nutrient delivery through the bloodstream. Even if nutrients are available, they can't reach the follicles that need them.
2. Environmental Damage
Decades of UV exposure, pollution, and styling heat accumulate faster on your scalp than your face, damaging the follicle environment.
3. Interrupted Growth Cycles
Your scalp can no longer maintain normal hair cycles, forcing follicles to exit the growth phase prematurely and remain stuck in shedding mode.
Are you finding clumps of hair in your brush? Noticing thinning at your temples? Seeing a wider part in the mirror?
These aren't isolated symptoms—they're direct results of the thyroscalp disruptions that make your scalp age 10x faster than it should.
"This discovery was revolutionary because it explained why conventional treatments like Rogaine and minoxidil show such disappointing results for thyroid-affected women," Dr. Kilgour notes.
But this was just the beginning.
What Dr. Kilgour uncovered next would challenge everything we thought we knew about treating hair thinning and shedding in women experiencing these scalp changes.
Real World Clinical Insights Into a Breakthrough Solution
As a Stanford dermatologist specializing in scalp health, Dr. Kilgour saw the devastating effects of thyroid-related hair problems first-hand in daily life through patients who were struggling.
While Dr. Kilgour can only help so many patients directly at the clinic...
In 2020, everything changed when a groundbreaking scientific study confirmed that the fundamental approach to solving hair growth problems had been wrong all along.
Researchers took young, healthy hair follicles and transplanted them into aged scalps... and they stopped growing.
But when they placed aged, dormant follicles into young scalps... something remarkable happened.
The follicles started growing again, and growing thick and fast - proving that the scalp environment, not the follicles themselves, controls hair growth.
This new research assured Dr. Kilgour that it would be possible for women to reverse the thyroscalp thinning and shedding at home.
"That’s when I became fully determined to create a new, comprehensive solution which would help women across the country and not only the women in my area, regardless of how long it took or how much money I would lose" Dr. Kilgour explains
"I became fully determined to create a new, comprehensive solution which would help women across the country and not only the women in my area..."
Despite knowing this would cost him thousands of dollars from his personal funds, Dr. Kilgour spent the next two years dedicating hundreds of hours of his free time, alongside his demanding daytime schedule at Stanford, to develop a solution that could address all 3 thyroscalp disruptions at once to make the scalp environment younger.
The potential to help millions of women mattered far more to him than any financial cost or personal sacrifice.
The result was a revolutionary approach that has been recognized by leading beauty publications like Vogue, Forbes, and Women's Health.
The innovative routine earned the Marie Claire 2024 Award for Best Medical-Grade Scalp Serum and the Elite Beauty Award 2024.
"For too long, women have been told that thinning hair is 'just genetics' or 'inevitable part of thyroid imbalances'," Dr. Kilgour says. "Recent science proves this simply isn't true—and more importantly, it doesn't have to be accepted."
The Daily Routine That's Changing Lives For Thyroid-Affected Women
Based on these scientific breakthroughs and his own first-hand experience, Dr. Kilgour developed what is now recognized as the first comprehensive routine designed to address thyroid-induced scalp issues.
The KilgourMD Dual-Action System takes a fundamentally different approach from conventional treatments by addressing all three aspects of Thyroscalp simultaneously to make the scalp younger.
"Most women diligently follow dramatic skincare routines for their face but use only basic shampoo and conditioner on their scalp, which ages 10 times faster," Dr. Kilgour says.
"Most women diligently follow dramatic skincare routines for their face but use only basic shampoo and conditioner on their scalp, which ages 10 times faster"
The KilgourMD Dual-Action System targets this thyroid-induced aging at its core by tackling each of the three disruptions at once:
Bypass Poor Circulation:
The routine uses breakthrough liposomal delivery, which bypasses compromised blood flow entirely. It essentially disguises active ingredients to mimic your scalp cells, which allows them to reach follicles directly through the scalp.
Balance The Environment:
Combining over a dozen natural botanicals including turmeric, pine bark, and amla, nature's most potent antioxidants, that work together to neutralize the flood of free radicals the system starts reversing your scalp’s biological age to where it should be.
Activate Growth:
Using follicle-reactivating compounds like Redensyl® and Anagain® the routine wakes up inactive follicles from endless shedding back into active growth phase in a new, younger, environment.
Addressing all three disruptions together, makes the scalp environment younger, this can activate growth even in areas you might currently think are gone forever.
"Because the scalp renewal cycle is just 14 days –twice as fast as facial skin– within just a few cycles, your scalp begins looking and functioning like it did years ago, and that's when the real transformation happens." Dr. Kilgour notes.
Clinical Proof That Shocked Experts
The proof is in the numbers. In a 24-week clinical study involving 120 participants, the ingredients were compared to 5% minoxidil—the current standard treatment for hair loss.
The results were astounding:
214% increase in hair growth
+10,200 hairs—better results than one hair transplantation procedure
81% more effective than minoxidil
Even more impressive was the safety profile...
While the KilgourMD system showed minimal side effects, minoxidil users experienced:
Itching and scalp irritation
Burning sensations
Unwanted hair growth in different body parts
"By making the scalp environment younger rather than forcing growth with harsh chemicals, we achieved better results naturally," notes Dr. Kilgour. "These results proved that addressing all three disruptions at once was the key that the industry had been missing."

What many women love the most–besides the results–is the routine’s simplicity. Simply apply a few drops of each serum in the evening, and you're done.
No complicated steps, no messy applications, just 60 seconds each evening before bed.
Life-Changing Results
The clinical data is impressive, but the personal stories from women with thyroid imbalances whose lives have been transformed are even more powerful:
Jessica, a 59-year-old from Seattle, had been struggling with thinning hair for years before trying the KilgourMD system:
"I've tried everything for my thinning hair—biotin, rosemary oil, even minoxidil which made my scalp so itchy I had to stop. KilgourMD is the first thing that has actually made a difference without irritation. My hair looks fuller, and I swear my shedding has decreased."
Lavanya, 41, shares her breakthrough: "After using this product for just two weeks, I am already seeing a significant decrease in my hair fall. As someone who has been skeptical of scalp care products in the past, I was relieved to discover that this product is developed by a dermatologist."
These aren't isolated cases. The KilgourMD website features hundreds of verified reviews from women who have experienced remarkable results:
"After 6 months of using the KilgourMD system, my hairline is visually back to where it was three years ago. I can only say I wish I had been using it sooner!" – Sarah, 48
"I began to notice a huge amount of hair fall - this serum has completely reversed it, and now my shower is no longer getting plugged so quickly with hair. I'm amazed at how tangible the results are." – Deanne, 39

Frequently Asked
Questions
Kindly provided by the Founder of KilgourMD, Stanford dermatologist, Dr. James Kilgour:
I’ve been told I have a specific type of thyroid imbalance—will this still work for me?
Whether you're experiencing thyroid-related changes, ongoing fluctuations, or symptoms that you can't fully define— this system is formulated to help support scalp and hair health in those circumstances.
That means it works across a wide range of thyroid-related changes—without requiring a specific diagnosis to be effective.
With natural, drug-free ingredients and advanced liposomal delivery, it's safe and effective for daily use.
As always, if you have a diagnosed medical condition or are taking medication, consult with your physician before use.
Isn't it just genetics?
Genetics can make your hair more sensitive to thinning. However, genetics alone don't seal your fate.
Factors like hormonal changes, the resulting oxidative stress, and accelerated scalp aging all drastically intensify hair thinning—even in those without a strong genetic predisposition.
The KilgourMD Dual-Action System is designed to address these triggers, neutralizing free radicals, restoring healthy growth cycles, and reversing the scalp aging that causes Thyroscalp...
As clinical studies on our active ingredients show, even if genetics aren't on your side, you can take control and promote thicker, healthier hair.
Does it work for all hair types?
Absolutely! The Kilgour MD Dual-Action system works through prinicipal, cellular level mechanisms to address hair loss areas that are universal across all hair types and textures...
Whether you have straight, wavy, curly, or coily hair, the underlying thyroid-induced hair thinning is driven by the same biological processes.
Our clinically studied & scientifically formulated approach targets the sources of thyroscalp disruption areas, making it effective regardless of your specific hair type or texture.
Can I use it if I have reactive or sensitive skin?
Our serums are specifically formulated to combine potency with gentleness and non-irritation, making them suitable for reactive and sensitive skin types.
We've carefully selected natural, clinically-studied ingredients that work harmoniously with your scalp's biology.
The liposomal delivery system ensures our active ingredients are absorbed without causing systemic inflammation or irritation.
We've also cultivated a specfic blend to soothe a sensitive scalp with ingredients like Bisabolol and Panthenol.
As always, if you have specific skin concerns, we always recommend consulting with your healthcare provider before making changes to your routine.
How long does one bottle of each serum last?
Each of our serums is 30ml, which should last one month with generous usage, but up to 3 months if used in a more targeted way.
What is the 30-day guarantee?
We offer a 30-day no-question refund on all of our products. If you don't see results within 30 days, you will get your money back in full, even if both bottles are empty.
Refunds are subject to our full refund policy.
After recovering my hair health,
do I stop using it?
It's common to consider stopping once your hair health improves, but maintaining some level of care can help sustain your results.
Thyroid-related hair thinning and shedding is a complex change and making the scalp environment younger is not a magic trick.
Here's two approaches our customers have often taken:
Gradual Transition: Instead of stopping abruptly, reduce serum use to 1-3 times per week to monitor your hair’s response.
Seasonal or Stress-Triggered Use: Reintroduce regular serum use during times of high stress or noticeable shedding/thinning.
Stopping completely is an option if the underlying causes are resolved and maintenance strategies are in place.
However, maintaining healthy hair and a young scalp environment requires ongoing care, especially under thyroid-related issues, so scaling back rather than stopping entirely is more effective.
