This article details laboratory methods for isolating and culturing human dermal papilla cells but provides no new experimental results.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This study found that α3β1-integrin is crucial for maintaining normal hair follicle morphology in mice, as its deficiency leads to severe abnormalities despite not affecting interfollicular epidermal differentiation.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This study found that using 3D Gel-C6S-HA scaffolds seeded with VEGF165-modified rat hair follicle stem cells enhanced angiogenesis and vascularization in tissue-engineered skin, improving wound healing.

The study found that exposing Arbas Cashmere goats to a short photoperiod significantly increased cashmere production by extending the anagen phase of hair follicles, with gene expression changes identified as contributing factors.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This article discusses isotretinoin for severe acne vulgaris, noting its effectiveness but also highlighting significant side effects on skin, mucous membranes, and hair; it reports no new clinical results.

This study found that the human placenta extracellular matrix hydrogel restored the hair-inductive capacity of high-passaged dermal papilla cells, enabling them to regenerate new hair follicles when co-grafted with mouse epidermal cells.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study found that both extensive grey hair and alopecia were independently associated with increased COVID-19 severity among survey respondents in Brazil.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

This study found that bio-based waterborne polyurethanes derived from castor oil may offer effective hair-styling performance without skin irritation and appear to be safer for the environment compared to traditional hair sprays.

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 study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

This study found that only minoxidil encapsulated in cationic vesicles significantly promoted hair growth in mice, likely due to its higher retention on the skin.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This review discusses the role of hair dyes in cosmetic dermatology, their effects on hair and scalp health, and the importance of dermatologists understanding potential side effects; it reports no new findings.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This article reviews haircare practices and hair cosmetics for patients with alopecia, emphasizing healthy scalp maintenance and caution in styling; it reports no new clinical results.

This case report describes dermoscopic features of pemphigus vulgaris on the scalp, highlighting that hair casts may suggest treatment adjustment for improved disease control.

This study indicates that hair analyses for calcium and phosphorus are unlikely to be useful for assessing the nutritional status of horses, suggesting soil and feed analyses as more effective alternatives.

In this study, using light masks to extend photoperiod was effective for maintaining the summer coat in horses and accelerating shedding in outdoor horses, but timing was crucial for success.

This study found that storing hair follicle micrografts in HEPES-buffered DMEM with ACD inhibitors like aminoguanidine significantly increased hair shaft elongation compared to phosphate-buffered salt solution, suggesting improved viability for transplantation.

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 reported that in the California Ground Squirrel, certain elements bioaccumulate in hair, providing baseline data for environmental health assessments.

This case report documents a woman with HIV who developed severe hair loss after starting lopinavir-ritonavir, which improved upon switching to a different antiretroviral drug.

Mink use L-methionine and L-cystine slightly better than natural amino acids for hair growth, but D-methionine is not effective.
