This study reported that using a herbal hair oil containing Cereus grandiflorus (cactus) Flower extract over 12 weeks was effective in significantly reducing hair fall and aiding new hair growth among alopecia patients.

This study found that Physcion from Polygonum multiflorum may be an effective natural 5α-reductase inhibitor for treating androgenic alopecia by enhancing hair growth and improving follicle morphology in laboratory settings.

This study measured elemental content in anagen hair fibers of Caucasian people aged 10-69 and found average levels of sulfur, zinc, calcium, and chlorine, establishing a baseline for future research.

The researchers reported that shiitake mushroom, buckwheat, soybean, cypress, and seaweed fulvescens showed potential as safe and effective natural ingredients for scalp care and scaling due to their antioxidative and antimicrobial properties.

This study found that cis-urocanic acid can engage in non-enzymatic reactions with reactive sulphur species, forming new metabolites, and suggests sulphide donors may protect against UVB-related toxicity.

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

This review assesses the potential of ginger, garlic, onion, and clove as complementary herbal treatments for hair and scalp health, reporting that onion juice shows the strongest clinical evidence for hair regrowth, particularly in alopecia areata, while garlic exhibits promising preclinical regenerative effects.

This study found that oral administration of Laminaria japonica and Cistanche tubulosa extracts may improve hair regrowth in mice, comparable to the effects of 3% Minoxidil, potentially due to their anti-inflammatory properties.

This study found that greater root surface area due to root hairs contributed to better growth and zinc uptake of wild-type barley compared to its root-hairless mutant in zinc-deficient soil.

This study examined hair classification based on geo-racial origin, observing that Caucasian and Mediterranean hair differs morphologically from African or Asian hair, with differences in density, thickness, and fiber shape contributing to varied hair characteristics such as color and curliness.

In this study, Ageratum houstonianum ethanolic extract and its active component agerarin were found to promote hair growth and follicle elongation by increasing SCUBE3 expression via activation of MAPK–AP-1 signaling in human dermal papilla cells, suggesting potential therapeutic value for treating hair loss.

This study found that hydromethanolic extracts from Carthamus caeruleus L. rhizomes exhibited notable antioxidant and anti-inflammatory effects in both in vitro and in vivo experiments, supporting its traditional medicinal uses and suggesting its potential as a source of therapeutic agents.

This study found that aerosols formulated with celery extract and candlenut oil significantly stimulated hair growth in rabbits without causing skin irritation, suggesting their potential as natural and safe alternatives for treating alopecia.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

This review explores the potential of Arabian Bidara leaves as a hair growth enhancer based on its shared chemical compounds with other known hair-fertility-promoting plants, but it reports no new experimental results.

This study found that several natural extracts, including Polygonum multiflorum Thunb and Terminalia chebula Retz., promoted hair growth in mouse models but showed limited effectiveness on human hair growth in vitro.

In this study, herbal hair oil formulated from Murraya koenigii, Hibiscus rosasinensis, and Lawsonia inermis showed promising properties such as good pH, acceptable viscosity, and stability at room temperature, suggesting potential for hair growth promotion in future formulations.

This study identified that the biosynthetic pathways for coumestans in Eclipta prostrata are derived from acetate and shikimate pathways, while phenylpropanoid biosynthesis is exclusively from the shikimate pathway.

This study suggests that a topical emulsion containing Camellia sinensis and Allium cepa extracts may show promise for treating alopecia areata in Wistar rats.

This study found that daily topical application of citral increased sebaceous gland lobules and cell hyperplasia in male rats after three months.

This study found that tomato plants inoculated with Enterobacter sp. SA187 grew better under salinity and heat stress, showing improved biomass, ion balance, chlorophyll content, and antioxidant enzyme activity, potentially enhancing crop tolerance to environmental stress.

This study found that cepharanthine and its structural analogues may stimulate hair growth by promoting the proliferation of human dermal papilla cells and increasing VEGF expression in vitro.

This study reported that a biotin-rich nutrition bar stored in aluminum foil packaging showed reduced bacterial growth and remained edible for 30 days compared to other packaging materials.

This study details the presence of two types of cysts in rhino mouse skin, with utricles derived from hair canals and deeper cysts from hair root sheath epithelium.

This systematic literature review identified kale leaf hair tonic (Ipomoea aquatica Forsk.) at 5% concentration as an effective herbal cosmeceutical preparation for enhancing hair growth, showing an average increase in hair length over 21 days, while meeting established pharmaceutical standards.

This study found that extracts of Punica granatum L. improved hair growth and demonstrated significant anti-lice and antidandruff activity in a mouse model.

This study found that Cacumen platycladi extract significantly promoted hair growth and reduced dihydrotestosterone levels by inhibiting 5α-reductase activity in an androgen-sensitive mouse model.

This study reported that methanolic extracts of Capparis decidua fruits showed significant in vitro thrombolytic activity, suggesting their potential as a dietary health supplement for preventing thrombotic cardiovascular diseases.

This study analyzed vegetable crops and found beets and potatoes to have high iron content, suggesting they can meet the daily requirements for essential minerals manganese and iron.
