This article reviews various topics discussed at a workshop on hair disorders, focusing on hair biology, diagnosis, and challenges in therapy evaluation, without presenting new clinical findings.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

TP0427736 may help treat hair loss by blocking a specific protein and promoting hair growth.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This review discusses the natural habitat, taxonomy, phytochemical components, pharmacological activities, and potential medical applications of Tridax procumbens but reports no new experimental findings.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

In this study, applying G. glabra root extract to female rats resulted in faster and more extensive hair growth than minoxidil or a control treatment.

In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

This study found that examining hair morphology provides deeper insights than classification, suggesting a potential population stratification artefact between hair curvature and cross-sectional shapes in the examined admixed African-European sample.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This review discusses the diverse phytochemical constituents and medicinal applications of Asteraceae family plants, noting their significance in traditional and modern medicine, but provides no new clinical results.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

The researchers reported that the antipsoriatic compounds 1,25-dihydroxy-vitamin D3 and calcipotriol thinned the living cell compartment in organotypic ORS cultures by accelerating the differentiation pathway rather than affecting proliferation.

This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.

This study found that treating androgenetic alopecia with platelet rich plasma increased hair density and diameter while decreasing the proportion of telogen and vellus hairs.

This review suggests that the inner root sheath of human hair follicles may have broader regulatory roles beyond structural support, potentially impacting processes like folliculogenesis, anagen phase regulation, and immunomodulation.

In this study, mycorrhizal fungal inoculation was associated with increased root-hair growth and enhanced drought tolerance in trifoliate orange by modulating auxin synthesis and transport under water stress conditions.

This review discusses the causes and diagnosis of traction alopecia, emphasizing education for high-risk populations as there is currently no cure, and presents no new clinical findings.

This study found that children with cancer showed more deviation from typical facial morphology compared to healthy controls, although the differences were not enough to distinguish patients from controls based on facial asymmetry alone.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

In this study, the growth-inhibiting potential of calcipotriol did not affect the telogen/anagen hair ratio during treatment for scalp psoriasis.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This article reviews the possible therapeutic activities of Angelica gigas Nakai root extracts and their components, noting their potential effects on neuro-cognitive, metabolic, and other health conditions, and reports no new clinical results.

This study suggests that although hydroxyapatite gel has strong bactericidal effects, its combination with platelet-enriched blood autoplasm does not enhance antibacterial activity in endodontic treatment for chronic apical periodontitis.

This case report suggests that intracanal medication with calcium hydroxide paste may alleviate colitis symptoms triggered by Formacresol used during dental retreatment in a 46-year-old patient.
