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 review discusses telogen effluvium and highlights the importance of considering seasonal hair shedding fluctuations in managing hair loss and evaluating hair growth treatments, without presenting new clinical findings.

This study found that in male badgers, seasonal molting and hair growth are influenced by cycles of plasma testosterone and thyroxine, with hormones affecting the timing and progression of these processes.

This study found that administering melatonin to ferrets can advance the timing of fur growth and reproductive cycles influenced by daylength and hormonal control.

This study reports a case where subcutaneous aeroallergen immunotherapy led to hair regrowth in a child with seasonal alopecia areata linked to rhinitis and allergen sensitivity, maintaining results over four years with some residual symptoms.

This article discusses inflammatory perifollicular fibrosis and alopecia but provides no new research findings.

In this study, changes in hair cycle phases during pregnancy and the post-partum period showed a rise in telogen rates after delivery, especially among non-breastfeeding women, but no drastic exaggerations were noted.

This article discusses abnormal fingerprints and their potential link to immigration delay disease, but it reports no new clinical findings.

This study found that a 60-second timed hair count is a practical and reproducible method for women to document hair shedding and treatment response at home, with significant differences in hair shedding observed between age groups in follow-up results.

This chapter reviews factors affecting hair growth and shedding and describes various conditions that can lead to hair growth diseases, but it reports no new clinical findings.

This study found that an adult female farm-raised blue fox exhibited an abnormal hair growth cycle and seasonal estradiol variation, with a delayed winter coat cycle resulting in spring shedding.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This study observed that pelage development in male blue foxes born in early June was more synchronized than those born in early May, with differences likely influenced by melatonin levels.

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 review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

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 review discusses various noninflammatory alopecias in horses, particularly alopecia areata, and reports no new treatment results, emphasizing the need for differential diagnosis through examination and biopsy.

This study observed that supplementing with vitamins, iodine, cobalt, and selenium prevented hair follicle growth arrest in Icelandic horses during winter.

This study found no significant difference in anagen rate improvement between the CYP-based dietary supplement and placebo in women over 60 with telogen effluvium, possibly due to variable patient inclusion related to hair growth seasonality.

This study reports that melatonin influences gene expression related to cashmere growth cycles in Inner Mongolian cashmere goats, potentially aiding in understanding and enhancing cashmere yield through molecular regulation.

This study presented cases of severe and permanent nail changes resembling lichen planus in patients with chilblain lupus erythematosus, suggesting a unique pattern related to cold exposure rather than typical histopathology findings.

This study found that cyclophosphamide treatment in cashmere goats significantly increased cashmere yield by inducing shedding without affecting fiber length, with a 20 mg/kg body weight dose being optimal for hair removal and regrowth.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This study introduces the concept of teloptosis, which influences hair shedding during the telogen phase and affects hair density, highlighting that early or delayed teloptosis has noticeable effects.

This study identified key genes and pathways involved in the seasonal hair cycle regulation of yak, uncovering molecular mechanisms that may aid in understanding their adaptation to alpine environments.

In this study, purebred Dexter cows with higher levels of winter hair shedding weaned heavier calves and had better reproductive success compared to cows with lower shedding levels.

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

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, 30% of a diverse female sample reported experiencing what they perceived as excessive hair shedding, often beginning abruptly and without an attributable cause.
