This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.

This study found that both finasteride and dutasteride led to morphological and functional kidney damage in rats, with more severe effects observed in the dutasteride group.

This review discusses the basic principles of hair pathology and findings in common types of alopecia but reports no new research results.

This study identified specific keratin-associated protein genes that are highly expressed in different varieties and sexes of Angora goats, providing insights for improving mohair development through targeted breeding strategies.

This review analyzes current hair transplantation methods, explores new classifications of alopecia, and discusses potential complications along with preventive measures in trichology and plastic surgery.

In this study, gene expression analysis of plucked hair follicles from scalp lesions was sufficient to differentiate chronic discoid lupus erythematosus from psoriasis and healthy controls, suggesting a non-invasive diagnostic potential.

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 found that patients with ovarian metastases from breast cancer had a better prognosis after tumor debulking if they exhibited high estrogen and progesterone receptor expression in both the primary tumor and metastases.

The document explains how hair follicles develop, their structure, and how they grow.

The study observed that in women, the number of hair follicles with an internal root sheath decreases with age in the parietal region, also hinting at a reduction in hair follicle and shaft width.

This review concludes that preoperative hormonal stimulation with testosterone or DHT may help increase penile length and glans circumference, easing hypospadias surgery and potentially reducing postoperative complications.

This review discusses the development and advances in studying trichogenic dermal cells for hair follicle morphogenesis, summarizing methods, bioassays, and molecular markers, but reports no new research findings.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This review highlights the evolution of forensic genetics from basic DNA analysis to complex genome-wide studies, enabling insights into personal traits, ancestry, and habits, and suggests future advancements through technologies like CRISPR and AI.

In this review, extensive analysis using conditional mutant mice revealed that androgen and Wnt signals play crucial roles in the development and function of male external genitalia and erectile tissue, while also exploring various regulatory factors involved in their pathogenesis.

This study used atomic force microscopy to identify significant morphological differences in hair from patients with lichen planopilaris compared to healthy controls, noting more scratches, uneven edges, and pitted scales in affected hair, which may aid future research on the condition.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This study identified over 40 phytochemical compounds in the leaves and flowers of Bituminaria bituminosa, predominantly glycosylated flavonoids from apigenin, using advanced chromatographic techniques.

This study found that single-dose x-ray irradiation in rat calvaria skin led to morphological changes in collagen fibers, disorganization, and a temporary absence of sebaceous glands and hair follicles.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

This study identified several genes regulated by dihydrotestosterone in an SV40T-transformed human dermal papilla cell line, which may play a role in androgen-mediated hair growth regulation.

This study found that platelet-rich plasma significantly increased hair diameter in both men and women with androgenetic alopecia but improved hair density only in men.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

The researchers concluded that hairless dogs can serve as an effective model for studying hypertrophic scarring due to their development of scars with morphological similarities to human hypertrophic scars.

This study found that an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.
