In this case report, a 7-year-old boy with patchy hair loss due to alopecia areata showed significant hair regrowth and improvement in psychological well-being after a holistic homeopathic treatment identified emotional distress as a root cause.

This case report describes a patient with mutations in both alleles of the vitamin D receptor who exhibited hair loss clinically indistinguishable from generalized atrichia with papules, suggesting a potential genetic pathway shared with the hairless gene.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

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

This study found that the Epilight multiple wavelength pulsed-intense light source was effective for long-lasting hair removal, particularly in individuals with dark hair and light skin.

This article reviews treatment options for androgenetic alopecia, highlighting potential uses of plant materials, but reports no new clinical results.

This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

In this study, aspartame consumption during gestation in rats was associated with significant histological changes and increased apoptosis in the skin of their neonatal pups.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

This case report reviews panfolliculoma, a rare benign follicular tumor, highlighting its occurrence and characteristics, and emphasizes the importance of accurate histopathological differentiation to avoid misdiagnosis.

A new mutation in the TRPS1 gene caused Trichorhinophalangeal syndrome in a 17-year-old, highlighting the need for genetic testing.

This study observed that hair loss in 110 patients most commonly appeared as patchy alopecia and was predominantly non-cicatricial and acquired in nature.

This study identified a new cytokeratin, mK6irs, specifically expressed in the inner root sheath of mouse hair follicles, distinguishing it as a member of the type II cytokeratin family.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.

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 found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

This study identified a new genetic variant in the KRT71 gene responsible for a breed-specific form of hypotrichosis in Hereford cattle, potentially serving as a model for similar human conditions.

This article reviews recent advancements in forensic hair testing, emphasizing its growing use for detecting past substance exposure, identifying emerging trends like micro-segmentation and hair scanning, and proposing standardized procedures to improve reliability and application in forensic toxicology.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

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.

This study found that permanent alopecia can occur after certain chemotherapy treatments and presents as nonscarring hair loss similar to androgenetic alopecia, with specific histological features that could be misdiagnosed without proper clinicopathological correlation.

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 exploratory study found that cannabidiol (CBD) at higher concentrations may inhibit hair growth by promoting the onset of catagen in human hair follicles, while lower concentrations showed potential anti-inflammatory effects without promoting catagen.

This study found that arbuscular mycorrhizal fungus inoculation and shading improved tea seedlings' growth, nutrient absorption, and stress resistance by enhancing root biomass and regulating phytohormone levels and gene expression.

This study found that laboratory-formulated natural shampoos condition hair better than commercial herbal shampoos, as shown by SEM micrograph analysis of hair microstructure.

This study found that the trichogenicity of cultured human outer root sheath follicular keratinocytes decreased with longer cultivation periods and was significantly influenced by the expression of the transcription factor FOXA2.

This study found that germ-free mice on a biotin-deficient diet exhibited significant weight loss and severe alopecia, unlike conventional mice on the same diet.

This study investigated the secretome of adipose mesenchymal stem cells and fibroblasts used in skin care products, finding 16 therapeutic pathways involving numerous signaling mechanisms, which may offer skin benefits through anti-inflammatory and regenerative effects.
