This study observed that the growth cycle of cashmere in Inner Mongolian cashmere goats consists of three phases, with genes KAP3–1, KRTAP 8–1, and KRTAP 24–1 closely correlating with this cycle.

This study reports that hair growth and shedding in healthy women show annual seasonal patterns, with the highest shedding in summer and a less pronounced peak in spring.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

The authors concluded that chronic telogen effluvium in middle-aged women presents distinct clinical and histological features that differ from androgenetic alopecia and acute telogen effluvium.

In this study, researchers found that the cashmere hair growth cycle is divided into three periods and key genes like KAP and KRTAP are positively correlated with these cycles in cashmere goats.

This study on Dorper sheep identified important genetic factors influencing hair follicle development, finding that expression patterns and genes like DBI, FZD3, and ZDHHC21 play a crucial role in wool shedding, which could help improve understanding of mammalian skin-related traits and human hair advancement.

This study identified important lncRNAs and genes associated with cashmere shedding in goats and explored their regulatory interactions, providing insights into the molecular mechanisms that may underlie this phenomenon.

This study found that a stochastic follicular automaton model replicates hair follicle cycle fluctuations, with deterministic simulations aligning with steady-state levels as follicle numbers increase.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This article reviews the historical development of understanding the hair growth cycle, particularly anagen, catagen, and telogen phases, and reports no new clinical findings.

This paper reports a rare case where AL amyloidosis presented as isolated scalp alopecia, underscoring the importance of considering systemic amyloidosis in the differential diagnosis of alopecia.

This article introduces a new grading system called the FPHL Severity Index to better identify and monitor early stages of female pattern hair loss using clinical criteria.

This article discusses the hair cycle of mice and its relevance in studying experimental carcinogenesis sequences, but it reports no new research findings.

This study suggests that chronic telogen effluvium may be due to a reduction in the variance of anagen duration, resulting in recurrent hair shedding with minimal long-term hair volume loss.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This case report describes a 16-year-old girl initially diagnosed with chronic telogen effluvium, later reassessed with Ludwig Stage 1 androgenetic alopecia, for which she began spironolactone treatment.

The conclusion is that different types of hair loss in dogs and cats can be cosmetic or serious, and affected animals should not be bred.

In this study, researchers analyzed skin samples from Dorper sheep to identify 395 differentially expressed long non-coding RNAs (lncRNAs) linked to hair follicle growth phases, suggesting these lncRNAs may play a role in the regulation of hair shedding through pathways like estrogen and PI3K-Akt signaling.

This case report describes how trichoscopy helped diagnose tinea capitis disguised as female pattern hair loss in cases of endothrix infection, highlighting its usefulness in avoiding misdiagnosis.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This review discusses the various triggers and diagnostic challenges in determining the cause of telogen effluvium-related hair loss, without providing new clinical results.

This report describes cases of increased hair loss and scalp sunburns in patients using 3% minoxidil and 0.01% tretinoin, suggesting caution with tretinoin use on sunny days.

This study found that continuous implantation of melatonin in cashmere goats advanced the growth cycle of cashmere by inducing secondary hair follicle development and altering gene expression.

This review discusses the effects of calorie restriction on skin aging, highlighting its potential to benefit skin health by reducing age-related and photo-induced changes, although the impact of certain diets remains unexplored.

In this study, researchers found that IGFBP‐rP1 levels were lower in individuals with androgenic alopecia compared to healthy controls, and subcutaneous injection of IGFBP‐rP1 showed potential in slowing hair loss progression in a mouse model by affecting the hair cycle transition.

This essay discusses telogen effluvium, the issues surrounding its diagnosis and differentiation from other forms of hair loss, and emphasizes the need for empathetic patient care; it reports no new clinical findings.

This review discusses telogen effluvium, including its triggers, clinical presentations, and management options, and does not report new research findings, emphasizing the need for identification and exclusion of underlying causes.

This paper identifies challenges in diagnosing alopecia variants, emphasizing the importance of pathologists understanding hair follicle histology, biopsy types, and collaborating with dermatologists to improve diagnostic accuracy.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.

Topical caffeine improves hair loss intensity, speed, and shedding, and works better with minoxidil/azelaic acid.
