In this study, deleting the Igf1 receptor in specific skin cells of mice affected hair follicle cycling but not overall skin health, suggesting Igf1r's role in hair cycle regulation through Bmp-4 activation.

This case report documents the first instance of acquired uncombable hair syndrome in a 39-year-old woman, characterized by diffuse alopecia and minimal upper lip hirsutism.

In this study, researchers explored the molecular and cellular traits of avian reticulate scales, finding that they lack localized stem cell niches for regeneration, unlike other scale types, leading to repair but not regeneration after wounding.

This case report describes a 2-year-old girl with loose anagen syndrome type B, confirmed by painless trichoscopic examination, with no signs in her identical twin sister.

This case report describes a 4-year-old boy with congenital alopecia characterized by complete irreversible hair loss and papular lesions associated with keratin-filled cysts.

This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This paper presents a case study of a 21-year-old male with thyroid hemiagenesis, where the left thyroid lobe and isthmus are absent, and discusses the anomaly's potential clinical consequences based on existing literature.

In this study, two patients with localized hair thinning showed histopathological signs typical of alopecia areata, responding to corticosteroid treatment similarly to classical cases.

In this study, researchers identified a mutation in mice that causes hair loss and immune system issues, located on chromosome 18.

Certain immune cells help hair growth by regulating iron in the skin.

This study found that transgenic mice overexpressing IKZF1 developed lesions similar to alopecia areata, suggesting that Ikaros may play a role in the disease's pathogenesis. Ikaros expression was also higher in human alopecia areata patients compared to controls.

This article discusses the limitations in the design or mechanism of hair implanter pens and reports no new findings.

This case report describes a 36-year-old man with tinea incognito manifesting as asymptomatic, flat patches of alopecia, which did not improve with standard treatments.

According to this study, Ireland’s current eligibility criteria for financial assistance on hair replacement products exclude many individuals with alopecia, such as children with non-chemotherapy-induced alopecia, and expanding support could align the country with more inclusive international policies.

This study found that maternal iron-restricted diets increased alopecia incidence in IL-10-deficient mouse pups with mast cells, implicating mast cells as potential effectors in this process.

This article discusses alopecia areata incognito, highlighting its diffuse hair loss pattern and favorable response to steroid treatment, but it reports no new clinical data.

Cathepsin L deficiency causes hair and skin issues in mice.

This study found that blocking LFA-1 signaling completely prevented the development of alopecia areata in C3H/HeJ mice, suggesting that LFA-1 plays a crucial role in the disease's pathogenesis and could be a target for new therapies.

This study observed four consanguineous families with congenital atrichia with papular lesions and identified three novel mutations in the hairless gene, which may contribute to the disorder.

This article discusses the immune privilege in hair follicles and suggests that restoring its collapse might be an effective strategy for treating alopecia areata and cicatricial alopecia, but it reports no new clinical results.

This letter raises concerns about the International Alliance of Hair Restoration Surgeons and reports no new research findings.

This article reviews alopecia areata incognita, a rare condition mostly seen in young women, and discusses its similarities and differences with telogen effluvium; however, it reports no new clinical findings.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

This paper reviews alopecia areata incognita, a condition causing diffuse hair loss without typical patches, and highlights the need for scalp biopsy for diagnosis, but reports no new findings.

This study identified a gene mutation in the LIPH gene associated with inherited hair loss and hair growth defects in certain populations, suggesting lipase H plays a role in hair development.

This study found that deleting Snai2 and Snai3 genes in mice disrupts immune cell development, resulting in severe autoimmunity and early death due to the loss of immune tolerance.

This study found that gap junctional communication influences feather patterning by modulating Turing-type activator-inhibitor systems in chicken skin, suggesting its role in propagating inhibitory signals crucial for pattern formation.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.
