research Characterization of Human Ovarian Teratoma Hair Using AFM, FT-IR, and Raman Spectroscopy
Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.
research Organization and Expression of Hair Follicle Genes
Hair growth is controlled by specific gene clusters and proteins, and cysteine affects hair gene expression in sheep.
research Reactive Keratin Derivatives: A Promising Strategy for Covalent Binding to Hair
Modified keratin binds better to hair, especially bleached hair.
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 A Novel Human Type II Cytokeratin, K6hf, Specifically Expressed in the Companion Layer of the Hair Follicle
K6hf is a unique protein found only in a specific layer of hair follicles.
research Cosmetic Approach for Healthy and Damaged Hair
Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.
research Asian Hair: A Review of Structures, Properties, and Distinctive Disorders
Asian hair is generally straight and thick, with unique disorders and properties, and more research is needed to understand it fully.
research Systems Approach to Human Hair Fibers: Interdependence Between Physical, Mechanical, Biochemical, and Geometric Properties of Natural Healthy Hair
Hair properties are interconnected; a comprehensive, cross-disciplinary approach is essential for understanding hair behavior.
research Hair Today, Gone Tomorrow: The Degradation and Conservation of Archaeological Hair Fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Expression of the Orphan Protein Plet-1 During Trichilemmal Differentiation of Anagen Hair Follicles
Plet-1 protein helps hair follicle cells move and stick to tissues.
research The Hair Follicle Enigma
The document concludes that understanding hair follicles requires more research using computational methods and an integrative approach, considering the current limitations in hair treatment products.
research The Structure of the Amorphous Matrix of Keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Investigation of Aging Effects in Human Hair Using Atomic Force Microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Proceedings of the Ninth World Congress for Hair Research 2015
The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Biomechanics of Hair Fiber Growth: A Multi-Scale Modeling Approach
