research Growth of the Hair
Hair growth is cyclic and influenced mainly by local factors.
research Molecular Dissection of Mesenchymal–Epithelial Interactions in the Hair Follicle
Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.
research Beta-Catenin Activity in the Dermal Papilla Regulates Morphogenesis and Regeneration of Hair
β-catenin in the dermal papilla is crucial for normal hair growth and repair.
research Anatomy and Physiology of the Skin
The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.
research Biology of the Hair Follicle: The Basics
The document concludes that understanding hair follicle biology can lead to better hair loss treatments.
research Probing the Effects of Stress Mediators on the Human Hair Follicle
Stress-related substance P may lead to hair loss and negatively affect hair growth.
research Smad7-Induced Beta-Catenin Degradation Alters Epidermal Appendage Development
Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.
research Hair Anatomy for the Clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Molecular Basis of Androgenetic Alopecia: From Androgen to Paracrine Mediators Through Dermal Papilla
Male pattern baldness involves hormones and cell signals affecting hair growth.
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses

research The Human Hair: From Anatomy to Physiology
The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
research Development and Progression of Alopecia in the Vitamin D Receptor Null Mouse
Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.
research Adenovirus-Mediated Wnt10b Overexpression Induces Hair Follicle Regeneration
Wnt10b overexpression can regenerate hair follicles, possibly helping treat hair loss and alopecia.
research Wnt Signaling in Skin Organogenesis
Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.
research Exosomal MicroRNAs Derived from Dermal Papilla Cells Mediate Hair Follicle Stem Cell Proliferation and Differentiation
Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.
research Proinflammatory Cytokines Regulate Epidermal Stem Cells in Wound Epithelialization
Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.
research Bone Morphogenetic Protein Signaling Regulates Postnatal Hair Follicle Differentiation and Cycling
Blocking BMP signaling causes hair loss and disrupts hair growth cycles.
research Physiological Regeneration of Skin Appendages and Implications for Regenerative Medicine
The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.
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 Normal Hair Growth in Children
Children's hair grows in different types from before birth through puberty, with growth rates and characteristics varying by age, sex, and race.
research MiR-218-5p Regulates Skin and Hair Follicle Development Through Wnt/β-Catenin Signaling Pathway by Targeting SFRP2
miR-218-5p helps skin and hair growth by targeting SFRP2 and activating a specific signaling pathway.
