Hairless protein helps control hair growth by regulating vitamin D receptor activity.

This review discusses various alopecic conditions in domestic animals, including their clinical and histopathological aspects, but reports no new experimental findings.

This review explores the crucial role of regulatory T cells in skin wound healing, emphasizing their involvement in balancing immune responses and promoting regeneration. It also discusses Tregs' operations in fibrosis, keloidosis, and scarring, suggesting a potential avenue for novel treatments.

This report documents the first known case of cutaneous mastocytosis associated with congenital alopecia areata in a young Korean girl, confirmed through histopathological examination.

This review examines a study showing that the balding scalp in men with androgenetic alopecia retains stem cells but lacks certain progenitor cells, suggesting new targets for future therapies; it reports no clinical results.

This study reports the first case of atrichia with papular lesions in a Taiwanese family without a detectable mutation in the HR gene.

This review highlights that microRNAs (miRNAs) play crucial roles in hair follicle development and cycling in cashmere goats, detailing recent advances in understanding their regulatory functions and potential applications in improving cashmere fiber quality and diagnosing hair disorders.

This study found that hair follicle stem cells in the hairpoor mouse, a model for Marie-Unna hypotrichosis, lose their quiescent state, leading to a disordered hair cycle and contributing to alopecia.

In this study, photodynamic therapy was found to achieve permanent reduction of nonpigmented hair in mice, unlike an 800-nm diode laser, by targeting the hair matrix through repeated sessions.

This study found that disrupted cholesterol homeostasis in scalp samples from cicatricial alopecia patients hinders hair regrowth by affecting hair follicle stem cell markers, with resulting effects confirmed in vitro and in animal models.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

The researchers reported that WNT10A gene variants are linked to short anagen hair syndrome, which suggests a potential genetic factor contributing to this hair condition.

This research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

This study suggests that nerve growth factor may support hair follicle growth in Liaoning cashmere goats through pathways involving its receptor, TrkA, particularly during the anagen phase.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

The mutation causes hairless mice due to mislocalized and dysfunctional HR protein.

Bulge progenitor cells show promise for regenerating hair follicles and increasing hair density.

This study found that Atractylodes macrocephala Koidz. extract promotes anagen entry and hair regrowth by enhancing dermal papilla cell activity and supporting hair cycle progression in a mouse model.

In this study, a botanical extract and minoxidil showed similar effects in vitro by reducing pro-inflammatory cytokines and 5α-reductase expression while increasing growth factors VEGF and KGF in human keratinocyte cells, suggesting potential for further in vivo research.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

This study reports conflicting evidence on whether GLP-1 receptor agonists are associated with various forms of alopecia, suggesting dermatology practitioners should consider monitoring and counseling patients using these medications.

Lemon-derived vesicles may help hair grow.

This study identified transcription elongation as a crucial regulatory factor in adipocyte cell fate, showing that the elongation factors Spt4 and Spt6 are essential for proper adipogenic differentiation by aiding RNA polymerase II progression through key adipogenic genes.

This study reviews melatonin's diverse roles in dermatology, highlighting its potential to protect skin from UV damage and oxidative stress, enhance DNA repair, and influence hair follicle cycling, suggesting therapeutic applications in skin care and hair renewal.

This literature review discusses the challenges and potential strategies for creating fully functional hair follicles capable of active cycling, emphasizing the molecular mechanisms, signaling pathways, and innovative regenerative techniques, such as hair micropatterning and three-dimensional printing, crucial for optimizing hair follicle regeneration.

This review explores the role of FGF signaling in hair follicle development and highlights its potential as a new therapeutic target for hair loss, which could surpass existing treatments in terms of efficacy and safety.

This study found that among various polyherbal hair oil formulations using indigenous Bangladeshi plants, Formulation B was most effective, displaying strong antimicrobial activity and promoting hair regrowth in rabbits, surpassing the standard 2% minoxidil treatment, while also being safe for topical use.

This case report of a four-year-old girl with Nicolaides-Baraitser syndrome highlights severe atopic dermatitis and worsening alopecia, suggesting that SMARCA2 dysfunction may impact skin barrier integrity and hair health, necessitating aggressive dermatologic treatment.

In this case report, researchers observed that scalp cooling during chemotherapy with doxorubicin and cyclophosphamide allowed a pregnant breast cancer patient to preserve nearly all her hair, suggesting such treatment may be a safe and effective option for managing chemotherapy-related hair loss during pregnancy.

This study found that NK and CD8+ T cell infiltration may drive inflammation in androgenetic alopecia, suggesting that targeting IL-15 signaling could offer a new therapeutic approach for hair regeneration.
