In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This study reports that milk goats exhibit significantly more differentially expressed genes related to hair follicle cycling across different months compared to cashmere goats, especially in December.

This review discusses the challenges in identifying specific hair follicle antigens involved in initiating alopecia areata and highlights the need for further research to understand its etiopathogenesis, reporting no new results.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This review discusses the limitations of current hair classification systems and highlights the need for standardized reporting of key hair characteristics to improve study comparisons; it reports no new results.

This study reports that hair fibers degrade most in acidic sandy clay, while silicone oil treatment is effective for conserving various hair types and artifacts.

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

This study found that topical formulations including extracts from Cuscuta reflexa, Citrullus colocynthis, and Eclipta alba significantly accelerated hair growth initiation and completion in rats, indicating potential benefits for treating alopecia.

This study identified novel genetic associations with skin phenotypes such as age-spots, freckles, and hair characteristics in Japanese women, providing insights into the genetic basis of these traits.

This study quantifies the follicular uptake of tea tree oil in bovine udder skin, with microemulsion showing the highest concentration among different formulations tested.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study found that petroleum ether extracts of Citrullus colocynthis reduced hair growth initiation time and advanced more hair follicles to the anagen phase in albino rats compared to untreated controls and minoxidil.

In this study, all stereoisomers of cyoctol were synthesized and tested, revealing that contrary to initial patent claims, cyoctol does not function as an anti-androgen.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

The researchers reported that keratin 33A is a structural protein specific to goat cashmere hair, with increased winter expression in high-cashmere-producing breeds.

This study identified a new class of shed hair in young women that could impact future hair research and suggests that the concept of hair miniaturization in androgenetic alopecia may need revision.

In this study, PEVIII, a nanocomposite chitosan-coated vesicle containing both α-hederin and hederacoside C, demonstrated notable antibacterial activity against Pseudomonas aeruginosa in a keratitis model, showing significant lesion reduction, tissue improvement, and decreased bacterial load and inflammatory markers compared to other treatments.

This study provided detailed anatomical, physico-chemical, and chromatographic analyses to differentiate Dracaena trifasciata from potential adulterants in traditional medicine.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This chapter reviews techniques for treating pseudofolliculitis barbae and suggests that combining daily shaving with topical treatments like glycolic acid may effectively manage this condition without new clinical results reported.

This descriptive literature review suggests that rosemary essential oil may stimulate hair growth in androgenetic alopecia with effects similar to 2% minoxidil, yet highlights the need for more robust clinical trials to confirm these findings and assess complementary methods like scalp massage and high-frequency treatment.

This study found significantly higher levels of Toll-Like Receptor 4, interferon gamma, and interleukin-17 in Iraqi patients with alopecia areata compared to controls, suggesting these immune markers play a crucial role in the disease's development and could be targets for future treatments.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.

This review discusses the role of steroid 5 alpha reductase 2 in converting testosterone to DHT and its association with conditions like benign prostatic hyperplasia and prostate cancer; it reports no new results.

In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

This study suggests that the serum marker may play a role in the pathogenesis of tinea capitis and could serve as an independent risk factor for assessing vulnerability, activity, and severity of the condition.

This review discusses a traditional medicinal plant used in various holistic health systems and reports its potential antitumor activity, but no new clinical results are provided.

This study undertook powder microscopy and preliminary phytochemical analysis of Buxus wallichiana's stem bark and leaves, identifying steroids, alkaloids, saponins, and glycosides without reporting clinical outcomes.

The researchers reported that the petroleum ether extract of Cuscuta reflexa may promote hair growth in testosterone-induced alopecia in mice by inhibiting the enzyme 5α-reductase.
