This study found that Biofield Energy Healing Treatment on a herbal mixture increased hair growth and melanogenesis in mice compared to an untreated group.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

Hair transplant complications were likely due to deep graft placement and rough handling.

In this study, researchers developed a model using iPS-derived cells to trace and evaluate hair follicle differentiation, which could aid in the development of hair growth treatments.

This study successfully grew and maintained human hair follicles in vitro, noting that TGF-β1 negatively affects growth, while EGF replicates hair-removal effects seen in animals.

A girl inherited excessive body hair from her mother and grandmother.

This study found that human dermal papilla cells reprogram into induced pluripotent stem cells with higher efficiency than dermal fibroblasts, demonstrating their potential as an alternative source for iPS cells.

This study found that human hair follicles can be used to generate induced pluripotent stem cells, which can then efficiently differentiate back into keratinocytes.

TRH in hair follicles can influence hair color by increasing melanin.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

This study developed a three-dimensional model for studying hair follicle development, showing that immortalized dermal papilla cells retain certain differentiation activities and can induce tubule formation in vitro.

This study shows that the Wnt-β-catenin pathway promotes TERT expression in both stem and cancer cells, linking tumorigenesis with pluripotency.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

Hormones cause hair loss by affecting cell growth and weakening cell attraction.

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

This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

This study suggests that human scalp hair follicles express erythropoietin and its receptor, up-regulating receptor expression under hypoxic conditions, and may mimic another hypothalamus–pituitary axis equivalent involving the TRH-TSH system.

In this case report, the authors suggest that a novel enhancer element's translocation near the TRPS1 gene may contribute to the TRPS phenotype, expanding understanding of the syndrome's genetic basis.

This study found that contrast enhanced phototrichogram (CE-PTG) significantly improved detection of various hair types and growth stages in androgenetic alopecia compared to standard PTG and was comparable to biopsy analysis.

This study proposed a detailed classification of psychodermatosis by examining three cases that illustrate the interaction between the brain and skin, resulting in conditions like trichotillomania and factitious dermatitis.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, researchers found that overexpression of IGF-1 in transgenic mice stimulated increased vibrissa growth during the first neonatal hair cycle compared to their nontransgenic littermates.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

This article reviews genetic mutations linked to monilethrix, a hereditary hair disorder, and reports no new clinical findings on the condition's variability in symptoms and severity.

The conclusion is that "trichoknesis" should be recognized as a separate condition from trichodynia, characterized by itching instead of pain.
