Does Polyporus Umbellatus Stimulate Hair Regrowth? Here’s What We Know

Hair loss and thinning continue to be major concerns for beauty consumers, and the search for solutions has expanded beyond conventional ingredients. Today, formulators and brands are looking closely at natural, science-backed options that also align with the rising demand for holistic beauty. One such cosmetic ingredient gaining traction is Polyporus umbellatus—a medicinal mushroom that has deep roots in traditional Chinese medicine. Thanks to advances in extraction technology and cosmetic science, this unique mushroom is now being explored for its potential to help reduce hair fallout and support the appearance of fuller, denser hair. But how strong is the evidence that it can stimulate regrowth? Let’s take a closer look. 

Known in traditional Chinese medicine as Zhu Ling, Polyporus umbellatus is a rare mushroom that grows at the base of hardwood trees. Historically, it’s been used for its diuretic and immune-boosting effects, but today it’s finding a new audience in the beauty world, especially in scalp and hair wellness. 
What makes this mushroom particularly interesting is its rich profile of polysaccharides, antioxidants, and other bioactives. When processed through eco-friendly extraction, it seems to do more than just support immunity—it can help calm scalp inflammation, reinforce the skin’s microbiome, and fight oxidative stress. And those factors matter: inflammation and oxidative damage are often tied to disrupted hair cycles and increased shedding. 
There’s also something compelling about its adaptogen-like properties. Many brands focused on holistic beauty are leaning into ingredients that help counteract stress, both on the skin and internally—and Polyporus umbellatus fits naturally into that story. 

Hair regrowth is a complex biological process that involves stimulating dormant hair follicles, prolonging the anagen (growth) phase, and supporting overall scalp health. Emerging research suggests that Polyporus umbellatus may offer benefits across these key areas.

Studies have shown that Polyporus umbellatus extracts are rich in polysaccharides and bioactive sterols, which exhibit strong antioxidant and anti-inflammatory properties. By neutralizing oxidative stress and calming inflammation around hair follicles, these compounds create a healthier scalp environment—an essential foundation for encouraging hair retention and regrowth. 
Some early laboratory studies also indicate that compounds within Polyporus umbellatus may help improve microcirculation in the scalp. Enhanced blood flow delivers more oxygen and nutrients to hair follicles, helping to revitalize and support the growth phase of the hair cycle. 
Additionally, because inflammation and oxidative damage are both linked to disruptions in hair cycle regulation, Polyporus umbellatus’ ability to reduce these stressors could help slow hair shedding and promote a denser, healthier appearance over time. While more human clinical data is needed to fully validate these effects, current evidence makes this traditional mushroom a promising active for innovative hair wellness formulations. 

Incorporating Polyporus umbellatus into hair care formulations offers several advantages, especially for brands and developers focused on scalp wellness, natural actives, and trend-driven innovation. 

• Reduces visible hair fallout: By creating a healthier scalp environment, Polyporus umbellatus can help minimize excessive shedding, supporting fuller-looking hair.
• Supports scalp microcirculation: Improved blood flow can nourish and energize hair follicles, promoting a more robust growth cycle.
• Anti-inflammatory and antioxidant protection: Ideal for products targeting scalp irritation, sensitivity, or stress-induced hair thinning.
• Natural and sustainable sourcing: Eco-extraction methods and a plant-based origin resonate with consumers seeking clean, conscious beauty solutions.
• Versatile application: Suitable for serums, scalp treatments, leave-on sprays, and shampoo or conditioner formulas focused on density, vitality, and wellness.
• Synergy with other actives: Works well alongside ingredients like caffeine, peptides, niacinamide, and botanical extracts aimed at scalp health and hair support. 

When formulating with Polyporus umbellatus, it’s important to consider appropriate use levels, compatibility with other bioactives, and the desired sensory profile of the final product to maximize efficacy and consumer experience.

The beauty industry is experiencing a significant shift towards natural, holistic solutions, with mushrooms emerging as a standout ingredient. The global mushroom cosmetics market was valued at approximately USD 1.88 billion in 2023 and is projected to grow at a CAGR of 5.0% from 2024 to 2030, reaching around USD 2.80 billion by 2030 .
