In this study, researchers found that fenugreek seed extract reduced prostate size, DHT levels, and cell proliferation in a testosterone-induced BPH rat model while modulating various genetic expressions, suggesting its potential as an alternative treatment for benign prostatic hyperplasia.

In this study, Tithonia diversifolia extract was found to improve certain digestive parameters in crossbred sheep but did not enhance growth performance, as the improvements in digestion did not translate into increased body weight or feed conversion.

Reishi mushroom extract may help treat hair loss.

This study suggests that a supercritical CO2 extract from wild-strawberry-processing waste may be an innovative and sustainable ingredient for cosmetic applications, particularly in treating androgenic-related skin conditions.

In this study, Rosa rugosa water extract improved hair length and thickness in a mouse model of DHT-induced alopecia by enhancing the expression of hair growth-promoting factors while inhibiting growth-suppressive proteins, suggesting its potential as a natural therapy for hair loss prevention.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

This study explored the antibacterial and wound-healing effects of an 80% methanol extract from Hibiscus micranthus leaves, finding it effective against several bacterial strains and beneficial for wound healing in rats.

In this laboratory study, coffee bean residue extract was observed to promote the proliferation of human hair follicle dermal papilla cells by activating autophagy, showing potential for treating hair growth disorders and hair loss.

This study found that extracts from orchid calluses can stimulate hair follicle growth and enhance the proliferation of hair follicle stem cells in vitro, suggesting potential applications in sustainable hair care products using natural bioactive compounds.

In this study, tea tree oil was found to have substantial antibacterial activity and promote proliferation and migration of hair follicle stem cells in vitro, indicating potential benefits for treating scalp alopecia areata.

This study found that a hair tonic containing 1% teak leaf extract significantly increased hair growth and user satisfaction in men with androgenic alopecia after 24 weeks, without causing adverse effects, and was comparable to the standard treatment, minoxidil.

This study found that a hair tonic formulated with 0.3% cocoa bean extract demonstrated the best physical stability and effectively promoted hair growth in mice, with results comparable to a positive control when used twice daily for two weeks.

In this study involving ICR mice, researchers found that Korean red pine bark extract improved cognitive functions impaired by TMT through mechanisms like antioxidant system protection, cholinergic and synaptic support, mitochondrial regulation, and reduction of neuro-inflammation and apoptosis.

In this study on male rabbits, a hair tonic formulated with delipidated ethanol extract of Capsicum frutescens L. leaves at concentrations of 5%, 10%, and 20% promoted hair growth more effectively than a placebo and similar to 2% Minoxidil at the highest concentration.

This study found that lipids extracted from Schizochytrium sp. significantly enhanced the proliferation and survival of dermal papilla cells under oxidative stress, reduced reactive oxygen species, inhibited ferroptosis, and promoted antioxidant genes, which improved hair growth in experimental settings, suggesting a potential treatment for alopecia.

Aloe vera extract helps heal burn wounds faster in rats.

This study evaluated a hair tonic formulated from oil palm leaf extract, finding it demonstrated very strong antioxidant activity and could prevent hair decolorization from sun exposure, with effective concentrations ranging from 25 to 200 ppm.

This study found that an herbal extract from Marking nuts, when compared to a standard drug, effectively inhibited the dandruff-causing organism Malassezia furfur and promoted hair growth on mice, suggesting potential use for dandruff treatment and hair rejuvenation.

Aloe vera may help heal burns by boosting skin cell growth.

This study found that Rumex japonicas Houttuyn ethanol extract may promote hair growth and protect against oxidative stress-induced hair damage in mice and HaCaT cells.
