research Antisense Oligonucleotide Targeting Fibroblast Growth Factor Receptor-1 Stimulates Cellular Activity of Hair Follicles in an In Vitro Organ Culture System
Targeting FGFR-1 with antisense oligonucleotides may help treat baldness by increasing hair follicle activity.
research Removal of Intact Hair Papilla and Connective Tissue Sheath by Plucking Anagen Hairs
Plucking hairs in a certain way can result in intact hair roots, not related to baldness.
research Transforming Growth Factor-Alpha Immunoreactivity During Induced Hair Follicle Growth Cycles in Sheep and Ferrets
TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.
research Knockdown of FOXA2 Impairs Hair-Inductive Activity of Cultured Human Follicular Keratinocytes
Reducing FOXA2 in skin cells lowers their ability to grow hair.
research Inhibition of Rab27a and Rab27b Has Opposite Effects on the Regulation of Hair Cycle and Hair Growth
Blocking Rab27a slows hair growth, while blocking Rab27b encourages it.
research Characteristic Localization of Neuronatin in Rat Testis, Hair Follicle, Tongue, and Pancreas
Neuronatin is found in specific cells within rat testis, hair follicles, tongue, and pancreas, suggesting it has various roles in tissue development and function.
research Expression Level of Prostaglandin D2 Receptor 2 Regulates Hair Regression
Higher levels of the DP2 receptor may lead to hair loss.
research Follicular Bisection in Hair Restoration: In Vivo Experiment
Splitting one hair follicle into two can help regrow hair with a 50% to 70% success rate, useful when donor hair is limited.
research IL-33 Contributes to the Pathological Changes of Hair Follicles in Psoriasis: A Potential Target for Psoriatic Alopecia
IL-33 is linked to hair follicle damage in psoriasis and could be a treatment target for hair loss in this condition.
research An Extract of Leontopodium Alpinum Prolongs Anagen Phase in Human Hair Follicles Ex Vivo
Leontopodium alpinum extract may help reduce hair shedding by keeping hair in the growth phase longer.
research Biological Effects of Electrical Epilation on Human Hair Follicles and Perifollicular Skin Ex Vivo
Electrical epilation damages hair follicles and surrounding skin, likely preventing hair regrowth.
research Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, Which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression
Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.
research Melatonin and the Hair Follicle
Melatonin helps regulate hair growth and protects the hair follicle from stress.
research Melanogenesis Is Coupled to Murine Anagen: New Concepts for the Role of Melanocytes and Regulation of Melanogenesis in Hair Growth
Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
research Characterization of Cell Cycle Arrest and Terminal Differentiation in a Maximally Proliferative Human Epithelial Tissue: Lessons from the Human Hair Follicle Matrix
CIP/KIP proteins help stop cell division and support hair growth.
research Hair Growth Promoting Effect of White Wax and Policosanol from White Wax on the Mouse Model of Testosterone-Induced Hair Loss
White wax and policosanol from white wax effectively reduced hair loss and promoted hair growth in mice better than a known hair growth drug.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research KF19418, A New Compound for Hair Growth Promotion in Vitro and in Vivo Mouse Models
KF19418 promotes hair growth similarly to minoxidil but is not better in live mice.
research Various Types of Minor Trauma to Hair Follicles During Follicular Unit Extraction for Hair Transplantation
Hair follicle damage happens during hair transplants and can impact success; better surgical methods are needed.
