research An overview of management of drug-induced hair and nail disorders
Cooling the scalp may prevent hair loss from chemotherapy, hair often grows back after treatment, and nail issues usually improve after stopping the drug.
research Straight to the Point: What Do We Know So Far on Hair Straightening?
Hair straightening can damage hair and pose health risks, including exposure to carcinogens and hair loss.
research MicroRNA-205 promotes hair regeneration by modulating mechanical properties of hair follicle stem cells
MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Hoxc13 mutant mice lack external hair
Hoxc13 gene is essential for hair, nail, and papilla development.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Loose anagen hair of childhood: The phenomenon of easily pluckable hair
Children with loose anagen hair have easily pluckable hair due to root sheath problems, and it might improve without treatment.
research Improving stable isotopic interpretations made from human hair through reduction of growth cycle error
The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.
research Physical Changes, Laboratory Parameters, and Bone Mineral Density During Testosterone Treatment in Adolescents with Gender Dysphoria
Testosterone treatment effectively causes male physical development in transgender male adolescents but may lead to side effects like acne, higher BMI and blood pressure, lower good cholesterol, and decreased bone density.
research Pharmacological BACE1 and BACE2 inhibition induces hair depigmentation by inhibiting PMEL17 processing in mice
Blocking BACE1 and BACE2 enzymes causes hair color loss in mice.
research A discourse on human hair fibers and reflections on the conservation of drug molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research Acquired Progressive Kinking of Hair
Acquired Progressive Kinking of Hair is likely an early sign of male pattern baldness.
research The Cross-section Trichometer: A New Device for Measuring Hair Quantity, Hair Loss, and Hair Growth
The Cross-section Trichometer is a new tool that can measure hair quantity and detect hair loss and growth.
research Exogenous and endogenous lipids of human hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research Cytokeratin 15 expression in central, centrifugal, cicatricial alopecia: new observations in normal and diseased hair follicles
CK15 is not a reliable marker for stem cells in damaged hair follicles from patients with CCCA.
research Analyzing the laser‐light reflection from human hair fibers. II. Deriving a measure of hair luster
The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.
research Marangoni effect in the water wetting of surfactant coated human hair fibers
The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
research Human long-term deregulated circadian rhythm alters regenerative properties of skin and hair precursor cells
Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.
research Types and Treatment of Hair Loss in Men and Women
The article concludes that different types of hair loss require specific treatments and psychological support is important.
research Keratin-mediated hair growth and its underlying biological mechanism
Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.
research Light Microscopic Hair Abnormalities in Children: Retrospective Review of 119 Cases in a 10-Year Period
Over half of the children had abnormal hair under a microscope, with many having genetic hair conditions.
research Involvement of the central hypothalamic-pituitary-adrenal axis in hair growth and melanogenesis among different mouse strains
Stress can slow hair growth and affect skin color by impacting the body's stress response system.
research Progress in Relevant Growth Factors Promoting the Growth of Hair Follicle
Growth factors are crucial for hair follicle growth and development.
research Molecular Pathways Involved in Promoting Activity of Timosaponin BII on Hair Growth in C57BL/6 Mice
Timosaponin BII, a plant extract, was found to promote hair growth in mice, similarly to minoxidil.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Enzymatic Method for Assessing Hair Damage with Reduction and Subsequent Oxidation
Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.
research Human scalp hair: Modulation by various factors and hormones do estrogens inhibit or stimulate—A perplexing perspective
The effects of estrogen on human scalp hair growth are unclear and need more research.
research Analysis of the Upper Face and Selection of Rejuvenation Techniques
Choosing the right eyebrow and forehead rejuvenation technique depends on the individual's features and goals, and even small changes can make a big difference in appearance.
