HAPPINESS GUARANTEED

Different by design

Most hair growth serums are built on the same idea: your scalp needs nutritional support. The problem here is that hair thinning isn’t always about vitamin deficiency. Instead of favouring these theories, we offer a proven holistic approach that combats all causes of scalp ageing.

Nature meets science

We combine the best plant-based ingredients with scientific research to provide a safe solution.

Clinically-proven results

We only use ingredients that are backed by scientific testing to promote hair growth

Dermatologist-created

Our dermatologist hair growth products are developed and led by Dr. James Kilgour, a leading expert in healthy skin, hair and nails.

KilgourMD is where mother nature meets science

KilgourMD is formulated exclusively based on peer reviewed, scientific evidence for maximum efficacy, using concentrated botanical extracts. Read more about the innovative research behind our products below. 

Scalp Health: The Foundation of Hair Growth

The condition of the scalp is integral to healthy hair growth, much like how fertile soil supports plant growth. A pivotal 2020 study published in PNAS demonstrated that the health of the scalp’s microenvironment directly affects the behavior of hair follicles. When young hair follicle stem cells were implanted into aged skin, the follicles stopped growing. However, implanting aged hair follicles into younger skin resulted in regrowth, reinforcing the importance of a healthy scalp. This highlights that maintaining a vibrant, fertile "soil" on the scalp is key for optimal hair growth.

Clinically Proven Actives for Superior Hair Care

Our products are powered by clinically proven ingredients that have been shown to be more effective than traditional treatments. A 2019 study in the Journal of Cosmetology & Trichology demonstrated that a combination of Redensyl®, Capixyl®, and Procapil® significantly outperformed 5% minoxidil in treating androgenetic alopecia in men, across all outcome measures. Unlike minoxidil, these ingredients have no known side effects, making them a safer, more effective alternative for long-term use.

In a 2020 study published in Dermatologic Therapy, Redensyl® was shown to improve hair density and quality. 73.1% of participants experienced moderate improvement, with many reporting increased satisfaction in their hair’s appearance. These results make Redensyl® a promising option for combating hair thinning.

Natural Ingredients Backed by Science

Our formulations also harness the power of nature, incorporating ingredients with scientifically proven benefits for the scalp. Rosemary extract, for example, has anti-inflammatory and antioxidant properties that help improve circulation in the scalp, promoting hair growth and preventing premature thinning. Rosemary oil can also reduce dandruff and soothe scalp irritation, contributing to healthier hair follicles.

Turmeric, specifically its active compound curcumin, is known for its ability to reduce inflammation and oxidative stress. Curcumin inhibits the enzyme 5α-reductase, which is responsible for hair loss, making turmeric a powerful ally in creating an ideal scalp environment for hair growth.

Pumpkin seed extract is another key ingredient. Rich in phytosterols and omega-3 fatty acids, it helps inhibit enzymes linked to hair loss, including 5α-reductase. Studies also show it contributes to overall scalp health by reducing inflammation and improving follicle function.

Pine bark extract is a potent antioxidant with anti-inflammatory properties that support a healthy scalp environment. It helps improve scalp circulation, which is essential for delivering nutrients to hair follicles and promoting hair growth.

Amla, a staple in Ayurvedic medicine, is rich in antioxidants and vitamin C. It has been shown to nourish hair follicles, enhance scalp health, and strengthen hair strands. In a 90-day clinical trial, amla extract improved hair growth rate, density, and reduced hair fall without causing any adverse effects.

Saw palmetto is a powerful natural ingredient that inhibits 5α-reductase and reduces androgen receptor activity in the scalp by up to 50%. This helps prevent hair loss and promotes stronger, thicker hair by creating a healthier scalp environment.

Ginseng is another key ingredient that stimulates hair follicles, promoting hair growth and preventing hair loss. Its anti-inflammatory properties also improve overall scalp health, strengthening hair and supporting thicker, fuller hair growth.

Caffeine has been shown to inhibit DHT, a hormone linked to hereditary hair loss (androgenetic alopecia). It also stimulates hair follicle activity and accelerates cell metabolism, supporting healthier hair growth. Studies suggest that caffeine’s ability to penetrate the scalp makes it an effective adjuvant in managing hair loss.

Combating Oxidative Stress and Inflammation

Oxidative stress is a significant contributor to premature hair loss and aging. In the scalp, oxidative stress accelerates hair follicle aging and impairs hair growth. Antioxidants like piroctone olamine, panthenol, and bisabolol target both the direct and indirect causes of oxidative stress, reducing inflammation and preventing hair shedding.

Piroctone olamine specifically helps control the growth of Malassezia, a fungus that contributes to scalp inflammation and dandruff. Studies have shown that piroctone olamine can reduce hair shedding and improve scalp health by controlling oxidative stress.

Panthenol, a form of vitamin B5, enhances scalp hydration, improves skin elasticity, and aids in the healing of skin inflammation. It also stimulates the proliferation of fibroblasts, promoting healthier scalp tissue and contributing to overall hair follicle vitality.

Bisabolol, derived from chamomile, has soothing, anti-inflammatory, and antioxidant properties. It helps calm sensitive scalps, reducing irritation and supporting a balanced, healthy environment for hair growth.

Liposomal Encapsulation for Enhanced Effectiveness

In addition to these potent ingredients, liposomal encapsulation technology improves the delivery and effectiveness of active compounds. For example, encapsulating ascorbic acid (vitamin C) in liposomes increases its absorption and enhances its ability to promote collagen synthesis, helping to repair UV damage and combat aging. This technology ensures that key ingredients penetrate deeper into the skin, maximizing their impact on scalp and hair health.
