On November 12, 2026, dermatologist-founded scalp health and hair growth brand KilgourMD unveiled its brand relaunch, including reformulated versions of its best selling scalp serums. These serums feature the company’s first two patent-pending actives developed through biotechnology: GlycoRoot and AndroLock.
KilgourMD was launched in 2024 and has reached over $100 million in annualized revenue run rate. The company closed a Series A funding round in March of this year, read by Prelude Growth Partners, to expand its ingredient pipeline and clinical research.
The Prevention Scalp Serum features GlycoRoot, an active ingredient that uses glycogen nanoparticles to deliver basil root extract into the hair follicle. In vitro tests showed that the ingredient restores natural trophic growth signalling in aging follicle cells and an increase of more than 215% in IGF-1 gene expression in testosterone-stressed cells. The brand’s Treatment Scalp Serum features AndroLock, a delivery technology that pairs saw palmetto with a bespoke peptide to carry actives deep into the scalp. The delivery peptide enhanced saw palmetto delivery by 47% in skin microscopy studies.
“When we launched KilgourMD, we had two serums and one conviction – hair loss deserves the same scientific rigor as any other medical concern,” said Dr. James Kilgour, founder and chief executive officer of KilgourMD. “Today, our customers trust us with something deeply personal, and that raises the bar for everything we do. This next chapter introduces our first proprietary actives, packaging designed around how our customers use our products every day, and an identity that reflects who we are: a company built on clinical evidence and empathy.”
In an independent, four-month clinical study, 43 menopausal-aged women with active hair shedding used the KilgourMD System, which includes the two serums and a shampoo and conditioner. The system demonstrated a reduction in shedding by 60.3% at four months, and 53% of participants showed clinically significant growth.
“As we begin this evolution, I want every detail to be fluent in the science and attuned to how personal hair loss is and the vulnerability it can create,” Dr. Kilgour explained. “The result is a brand that is as emotionally compelling as its science is rigorous.”
