This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

Mesotherapy shows promise for cellulite and facial rejuvenation but has mixed results for body sculpting and hair loss, with more research needed for safety and effectiveness.

This study examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study found that melatonin exposure promoted hair follicle fiber growth in Cashmere goat cultures, potentially influencing pathways related to the microvascular system and extracellular matrix.

This review examines the life cycle, biomarkers, and functions of hair follicle stem cells, emphasizing their role in hair loss therapy and other skin and hair disorders, but reports no new clinical results.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This review discusses recent advances in hair regeneration therapies, highlighting the potential of nanotechnology and pluripotent stem cells, and reports no new results, emphasizing the need for further research.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This preliminary study suggests that Raman micro-spectroscopy can help differentiate basal cell carcinoma from hair follicles in skin tissue sections, although some misclassification of hair follicles as carcinoma was observed.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents 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.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

In this study, adding CCL2 protein to organoid cultures helped adult skin cells regain the ability to self-organize and regenerate hair follicles, suggesting potential therapeutic applications.

This review examines the recent progress in using bioactive molecules for skin regenerative medicine and reports no new clinical results; the authors suggest this method could become a promising strategy for in situ skin regeneration.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This article discusses the potential for targeted therapies in hair loss by exploring inflammatory and cytokine-mediated processes, but it presents no new clinical results.

This study found that extracellular vesicles derived from mesenchymal stem cells and umbilical cord blood plasma enhanced wound healing and reduced scar formation in mice, suggesting their potential as therapeutic agents for skin repair.

This study found that white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

In this study, researchers found that synchronization between expanding epithelial cells and background mesenchymal cells in the mouse hair cycle may be maintained by inhibitory regulation, with potential mediators of this regulation identified.

This study suggests that the water fraction of Chrysanthemum zawadskii extract promotes hair growth by inducing telogen hair follicles in mice to enter the anagen phase and stimulating cell differentiation.

This study suggests the possibility of regenerating hair follicle structures in vitro using hiPSC-derived cell composites, which might reduce reliance on human tissue-derived cells for hair bioengineering.

This study found that circRNA-0100 promotes differentiation of secondary hair follicle stem cells into hair lineage in cashmere goats by sequestering miR-153-3p, which enhances KLF5 expression.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.
