- A new scalp serum combining plant-derived vesicles from Centella asiatica with engineered growth factors more than doubled hair thickness and density in a clinical trial.
- The 56-day study of 60 adults found the full formula produced 101% greater improvement in hair thickness and density compared to a placebo.
- Participants using the complete serum gained an additional 3.5 cm of cumulative hair growth and experienced significantly less hair shedding.
- The research suggests a synergistic effect, where the combination of natural plant signals and lab-engineered proteins outperformed any single ingredient.
- While promising, experts note the study is small and preliminary, requiring larger, longer-term trials before such a treatment could become widely available.
In the enduring quest to combat hair loss, a novel approach blending ancient botanical wisdom with modern biotechnology has shown striking results. Researchers in Taiwan have developed a topical serum that, in a controlled clinical trial, more than doubled improvements in hair thickness and density within just eight weeks. The key innovation lies in harnessing the natural communication system of a common tropical plant, Centella asiatica, and combining it with lab-engineered proteins to create a synergistic treatment. This development offers a new, potentially potent strategy for the millions worldwide seeking solutions for thinning hair, moving beyond conventional treatments with a formula designed to actively stimulate the scalp’s hair-producing machinery.
The science of synergy
The research, conducted by a team in Taipei and published on the preprint server medRxiv, was built on a multi-targeted hypothesis. The scientists formulated several versions of a serum, each adding a layer of complexity. The base contained caffeine, known for stimulating scalp circulation, and panthenol, a moisturizer. To this, they added two lab-grown proteins: Fibroblast Growth Factor 7 (FGF7), which supports the cells responsible for hair production, and Insulin-like Growth Factor 1 (IGF-1), a known promoter of hair follicle development. The critical botanical component was extracellular vesicles—tiny, message-carrying bubbles—derived from C. asiatica, a plant long revered in traditional medicine for its healing and anti-inflammatory properties.
The study involved 60 healthy adult volunteers, who were divided into five groups to test a placebo, the base formula, the base plus growth factors, the base plus plant vesicles, and a “full” serum containing all active ingredients. Participants applied their assigned serum daily for 56 days. Using AI-powered digital microscopes, standardized comb tests for shedding, and clinical photography, researchers meticulously tracked changes.
Quantifiable results in a short timeframe
The data revealed a clear, stepwise improvement correlating with the complexity of the formula. While all active serums outperformed the placebo, the full combination was decisively superior. After eight weeks, the group using the complete serum saw a 101% greater increase in both hair thickness and density compared to the placebo group. Their cumulative hair growth was 17% faster, resulting in an extra 3.5 centimeters of new hair. Furthermore, they experienced 47% less hair shedding and a 25% greater reduction in excess scalp oil.
When analyzed individually, the engineered growth factors proved to be the single most powerful component. However, the plant vesicles from C. asiatica also provided substantial benefits on their own. The researchers concluded that the true power of the treatment emerged from the synergy of all components working together, suggesting the plant-derived vesicles may help create a healthier scalp environment or enhance the delivery and effectiveness of the growth signals.
The modern hair loss landscape
The pursuit of hair restoration is ancient, with remedies documented in Egyptian papyri and Greek texts. In the modern era, the landscape has been dominated by two FDA-approved pharmaceutical options: minoxidil (a topical treatment) and finasteride (an oral medication). While effective for many, these treatments don’t work for everyone, can have side effects, and require indefinite use to maintain results. This has fueled continuous research into alternative mechanisms, from stem cell therapy to JAK inhibitors.
The Taiwanese study taps into two growing trends in cosmetic and therapeutic science: the use of growth factors to directly manipulate cell behavior and the exploration of plant-derived exosomes or vesicles as natural delivery and signaling systems. C. asiatica itself has a rich history in Ayurvedic and Chinese medicine for wound healing, making its application to scalp and follicle health a logical, modern extension. This research represents a convergence of these avenues, proposing that nature’s own cellular messengers can be partnered with precise bio-engineered cues for a more holistic intervention.
Cautious optimism and the path forward
Despite the compelling results, experts urge cautious optimism. The study was relatively small, of short duration, and conducted on individuals without diagnosed pattern baldness. Christos Tziotzios, a hair loss specialist at King’s College London who was not involved in the research, noted to New Scientist that while the findings are “potentially interesting,” they “need further work obviously.” Key questions remain about long-term efficacy, performance in a clinically balding population, and how the serum would compare directly to established treatments like minoxidil.
The next necessary steps involve larger, longer-term and independent clinical trials that include participants with male or female pattern hair loss. These studies must also prioritize safety monitoring and direct head-to-head comparisons with current standard therapies to determine if this synergistic approach offers a meaningful advantage.
A new branch on the hair growth tree
For now, minoxidil and finasteride remain the evidence-based cornerstone of treatment. However, the study from Taiwan plants a significant flag in the field of hair restoration research. It demonstrates that a formula leveraging both natural plant communications and targeted growth factors can produce measurable, significant improvements in hair growth metrics in a remarkably short timeframe. While not an immediate cure, this serum represents a promising new branch of inquiry. It underscores a future where hair loss treatments may become increasingly sophisticated, combining the best of biotechnology with compounds from the natural world to more effectively awaken and sustain the hair follicle’s innate potential.
