This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

Isolated patchy heterochromia with pili annulati can occur without other health issues.

In this study, calves fed skim milk and soybean oil experienced hair loss over the perineal region, which regrew once they began consuming hay or grain, despite continuing the same diet.

This study developed and tested two methods to accurately quantify hair growth rates in polar, black, and grizzly bears using dye application and isotopically labelled amino acids, revealing growth rate variations by individual and season.

This study reported that 39.7% of Amargosa voles had mite-associated lesions, which may severely impact their health and fitness.

This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

This study found that transgenic mice expressing cgVEGF164 had increased hair follicle diameter and density, potentially linked to higher phosphorylation levels of ERK1/2, AKT1, and LEF1 proteins.

This study found that a refined wash test can effectively differentiate shedding hair characteristics among normal individuals, and patients with androgenetic alopecia or telogen effluvium, aiding in diagnosis and monitoring.

In this study, ivermectin treatment in affected Columbian black-tailed deer was associated with increased weight gain, reduced parasites, and faster hair regrowth compared to untreated deer.

Estrogen receptor α controls hair growth cycles and skin thickness in male mice.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

This study identified 4,942 differentially expressed genes between Jiangnan cashmere goats and Changthangi pashmina goats, enriching pathways like PI3K-Akt and thermogenesis, which may influence cashmere fiber quality, offering insights for their genetic improvement.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This article provides an overview of diagnosing Cushing's syndrome, emphasizing the importance of assessing clinical signs and the appropriate use of first-line biochemical screening.

This report describes eleven cases of thallium poisoning in individuals who consumed tortillas made from barley mixed with thallium sulphate, leading to symptoms including tingling, abdominal pain, vomiting, and limb weakness.

This study found that human umbilical cord blood mesenchymal stem cells promoted hair growth by advancing anagen onset and increasing hair follicle regeneration in an in vivo model.

This report is the first to associate Cronkhite-Canada syndrome with multiple myeloma, describing regenerative pseudopolyps in a 58-year-old woman rather than true adenomatous polyps.

This case report describes a 26-year-old female with linear morphea and unique alopecia characterized by atrophic follicular remnants, resembling telogen follicles but indicating permanent alopecia, unlike typical findings in morphea-related alopecia.

This article is a correspondence discussing the possibility of the Mona Lisa exhibiting frontal fibrosing alopecia instead of Renaissance fashion, but it reports no new clinical findings.

In this study, subcutaneous platelet-rich plasma injections improved hair density and histological markers of hair growth in hairless rats without causing local toxicity.

This chapter reviews common cosmetic dermatology techniques but presents no new findings; it discusses treatments like emollients and laser therapy for conditions like photoaged skin and acne scarring.

This study suggests that scalp massage may reduce stress, as indicated by decreased salivary cortisol and increased secretory immunoglobulin A, and improve comfort by reducing physical fatigue and negative emotions.

This case report describes a new family with autosomal recessive hypotrichosis simplex with woolly hair, suggesting the disorder may be underreported due to misdiagnosis.

This study evaluated the therapeutic response of an Afro-descendant patient with non-scarring alopecia after prolonged use of alkaline straighteners and mechanical traction, highlighting the susceptibility of Afro hair to chemical and mechanical damage due to its structure.

Results are not reported for this study exploring how herbal hair dye, made from natural plant-based ingredients, might promote glossier, longer, and thicker hair while covering gray.

This article reviews drug-induced alopecia, its diagnosis, and treatments, but presents no new clinical findings.

This article reviews the phases of hair growth and differences between androgenetic alopecia and telogen effluvium but provides no new clinical findings on Electric Follicle Stimulation.

This study found that clinical examination is effective for diagnosing certain non-scarring hair loss types in women, although histopathologic studies are necessary for exact diagnoses, and laboratory tests did not correlate well with clinical findings.
