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.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This study observed that hair breakage may indicate early central centrifugal cicatricial alopecia in African American women, suggesting that it should be considered in their differential diagnosis.

Overexpression of certain genes can shorten hair by disrupting the hair-growth cycle.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

In this study, DHT was found to inhibit hair growth in mice by decreasing IGF-I production in dermal papillae through reduced sensory neuron stimulation.

This review discusses diagnostic challenges and management approaches for pediatric hair disorders, emphasizing the importance of distinguishing between acquired and congenital conditions, and reports no clinical results.

This study found that the absence of sebaceous glands may be an early factor in the development of keratosis pilaris, leading to hair shaft and skin barrier abnormalities, independent of filaggrin mutations.

This review discusses the biology of hair follicles and common hair disorders in the elderly but reports no new clinical results.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.

In this study, Nec-1s was found to promote hair growth and may target necroptosis and the Wnt/β-catenin pathway for potential treatment of hair loss.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

Mother and son diagnosed with a rare genetic hair loss condition with no effective treatment.

This review discusses various pediatric hair loss conditions and treatments, highlighting the importance of a holistic approach and noting that no single treatment is universally effective.

This article reviews the structural similarities and common disorders of hair and nails, highlighting their joint involvement in congenital and acquired conditions, but it reports no new clinical results.

Eating a balanced diet with the right vitamins and minerals is important for healthy hair, but too many supplements can be harmful.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

This article discusses loose anagen syndrome, highlighting its characteristics, diagnostic methods, and spontaneous improvement over time, but provides no new clinical results.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.
