This study found that extracts from the fungus YL161, Agaricus blazei, and the bark of Camptotheca cuminata promoted dermal papilla cell growth more effectively than pentadecanoic acid, suggesting potential for stimulating hair growth.

In this study, Gardenia florida fruit extract promoted hair growth in vitro and in vivo by enhancing hair growth-promoting gene expression and increasing hair follicle number, size, and depth in mice.

This study suggests that a herbal extract from Gardenia, Mentha arvensis, Rosemary, and Lavender may promote hair growth in mice at a rate comparable to minoxidil.

This study found that water extract of Puerariae Radix may promote hair growth by increasing the mRNA expression levels of hair growth-related genes in human dermal papilla cells, unlike the juice extract.

In this study, Salvia plebeia extract promoted hair growth by enhancing proliferation and anti-apoptotic effects in human dermal papilla cells and increased hair growth in treated mice.

This study found that Ganoderma Lucidum extract and its active component, Ganoderic acid A, improved hair cell proliferation and growth factor expression in lab and clinical settings, demonstrating significant hair loss inhibition effects when used in shampoo and tonic formulations over 24 weeks.

This study found that combining sorafenib with Platycladus orientalis leaf extract effectively suppressed cervical cancer cell growth by increasing tumor suppressor gene expression and reducing anti-apoptotic gene expression, suggesting a potential rationale for further clinical trials.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

This study found that a 15% Pisum sativum extract concentration in hair tonic showed the most effective hair growth, with a length of 14.51mm and weight of 0.16g.

This source reviews recent research on Ginkgo biloba, highlighting its medicinal benefits due to compounds in the leaves and concerns over toxic alkylphenols in seeds. It also discusses patents for its food production uses and ongoing studies on toxicity and drug interactions.

In this study, researchers tested hair tonic formulations with varying concentrations of bitter melon extract and found that higher concentrations enhanced hair growth in rabbits, with the 15% extract showing the greatest effect without causing skin irritation.

This study found that TSG-enriched Polygonum multiflorum extract, optimized through microwave-assisted and chromatographic methods, promotes hair regrowth in a mouse model of androgenetic alopecia via 5α-reductase inhibition and Wnt/β-catenin pathway activation, suggesting its potential as a natural treatment.

In this study, Platycladus orientalis leaf extract loaded into hyaluronic acid microneedles was found to promote hair follicle growth by enhancing the environment for hair cell proliferation and activating repair pathways, suggesting potential as a treatment for androgenic alopecia.

This study examined the extracts and essential oil from Platycladus orientalis leaves and found that the ethanol extract had the highest antioxidant activity, while the essential oil was more effective as an antibacterial agent, particularly against Micrococcus luteus and Staphylococcus aureus.

This study found that extracts from Angelica gigas Nakai and Glycyrrhiza uralensis stimulated hair regrowth and follicle development in a shaving mouse model, suggesting potential for hair growth or hair loss prevention in humans.

This study found that Plumbago zeylanica extract and its component plumbagin may help prevent androgenetic alopecia by promoting dermal papilla cell growth and reducing SRD5A2 expression.
