research Disruption of Smad4 in Mouse Epidermis Leads to Depletion of Follicle Stem Cells
Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.
research WNT Signaling in the Control of Hair Growth and Structure
The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.
research Dermal papilla cell number specifies hair size, shape and cycling and its reduction causes follicular decline
More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.
research The Cytology and Cytochemistry of the Wool Follicle
Wool follicles are complex, involving interactions between different cell types and structures.
research Fibroblast Growth Factors Stimulate Hair Growth throughβ-Catenin and Shh Expression in C57BL/6 Mice
Certain growth factors can promote hair growth in mice by activating hair growth-related proteins.
research Cyclosporin A-induced hair growth in mice is associated with inhibition of calcineurin-dependent activation of NFAT in follicular keratinocytes
Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
research Stem cell plasticity enables hair regeneration following Lgr5+ cell loss
Hair can regrow after certain stem cells are lost because other stem cells can take over their role.
research Exogenous IGF-1 promotes hair growth by stimulating cell proliferation and down regulating TGF-β1 in C57BL/6 mice in vivo
IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.
research Macroenvironmental Regulation of Hair Cycling and Collective Regenerative Behavior
Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.
research Identification of microRNAs in Wool Follicles during Anagen, Catagen, and Telogen Phases in Tibetan Sheep
MicroRNAs play a key role in wool growth in Tibetan sheep.
research Alopecia Areata in C3H/HeJ Mice Involves Leukocyte-mediated Root Sheath Disruption in Advance of Overt Hair Loss
Hair loss in mice starts with immune cells damaging hair roots before it becomes visible.
research Hair Regenerative Mechanisms of Red Ginseng Oil and Its Major Components in the Testosterone-Induced Delay of Anagen Entry in C57BL/6 Mice
Red ginseng oil and its components help promote hair regrowth and could treat hair loss.
research The Basic Science of Hair Biology
Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.
research Hair regrowth through wound healing process after ablative fractional laser treatment in a murine model
Laser treatment helped regrow hair in mice by activating a key growth pathway.
research Exogenous stimulation with Eclipta alba promotes hair matrix keratinocyte proliferation and downregulates TGF-β1 expression in nude mice
Eclipta alba extract helps increase hair growth and decrease hair loss-related protein in mice.
research Polyclonal origin and hair induction ability of dermal papillae in neonatal and adult mouse back skin
Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.
research Dihydrotestosterone Regulates Hair Growth Through the Wnt/β-Catenin Pathway in C57BL/6 Mice and In Vitro Organ Culture
Dihydrotestosterone affects hair growth by changing the Wnt/β-catenin pathway, with low levels helping and high levels hindering growth.
research Human umbilical cord blood mesenchymal stem cells engineered to overexpress growth factors accelerate outcomes in hair growth
Modified stem cells from umbilical cord blood can make hair grow faster.
research Contribution of hair density and hair diameter to the appearance and progression of androgenetic alopecia in Japanese men
Hair thickness matters more than density for baldness in Japanese men over 25.
research Activation of Wnt/β-catenin signaling is involved in hair growth-promoting effect of 655-nm red light and LED in in vitro culture model
Red light and LED treatments help hair grow by activating a specific cell signaling pathway.
research Stimulatory Effect of Brazilian Propolis on Hair Growth through Proliferation of Keratinocytes in Mice
Brazilian propolis was found to speed up hair growth in mice by increasing the growth of skin cells that form hair.
research Dietary vitamin A regulates wingless-related MMTV integration site signaling to alter the hair cycle
Eating vitamin A affects hair growth and health by changing cell signals in mice.
research Genetically Induced Cell Death in Bulge Stem Cells Reveals Their Redundancy for Hair and Epidermal Regeneration
Hair and skin can regenerate without bulge stem cells due to other compensating cells.
research Topical Inhibition of the Electron Transport Chain Can Stimulate the Hair Cycle
Applying certain inhibitors to the skin can promote hair growth without harming cells.
research Chemotherapy-Induced Hair Loss: The Use of Biomarkers for Predicting Alopecic Severity and Treatment Efficacy
Scalp cooling to prevent hair loss from chemotherapy works for some but not all, and studying hair damage markers could improve prevention and treatment.
research Decorin promotes proliferation and migration of ORS keratinocytes and maintains hair anagen in mice
Decorin helps hair cells grow and move, and keeps hair growth phase going in mice.
research Deficiency in Nucleotide Excision Repair Family Gene Activity, Especially ERCC3, Is Associated with Non-Pigmented Hair Fiber Growth
Low ERCC3 gene activity is linked to non-pigmented hair growth.
research Non-thermal plasma promotes hair growth by improving the inter-follicular macroenvironment
Non-thermal plasma helps hair grow by improving the area around hair follicles.
research Blackcurrant Extract with Phytoestrogen Activity Alleviates Hair Loss in Ovariectomized Rats
Blackcurrant extract may help reduce hair loss by promoting stem cell activity in hair follicles.
