research Melatonin promotes secondary hair follicle development of early postnatal cashmere goat and improves cashmere quantity and quality by enhancing antioxidant capacity and suppressing apoptosis
Melatonin improves cashmere goat hair growth and quality by increasing antioxidants and reducing cell death.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Curly hair: measured differences and contributions to breakage
Curly hair breaks more easily, especially with chemical treatments, but simpler grooming reduces breakage.
research A highly resistant structure between cuticle and cortex of human hair
A tough membrane between the outer and inner layers of human hair protects it from damage.
research Hair keratin film as a substitute device for human hair
Keratin film can effectively replace human hair for testing hair damage.
research Controversy: Synthetic hairs and their role in hair restoration?
Synthetic hair fibers for hair restoration were controversial in 2009 due to health risks and lack of support from the International Society of Hair Restoration.
research Structural changes of hair shaft after application of chemical hair straighteners: Clinical and histopathological study
Chemical hair straightening improves smoothness and shine but may cause side effects, suggesting a need for safer methods.
research Hair, Human Evolution, and the Idea of Human Uniqueness
Human hair is unique and important for understanding human evolution and identity.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Microstructure of Defective Mink Guard Hair
Defective mink guard hairs have split tips and missing cuticle cells, causing a metallic sheen.
research Ancient lineages of the keratin-associated protein (KRTAP) genes and their co- option in the evolution of the hair follicle
Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.
research Study on Advances of Medicine and Its Active Ingredient on the Hair Follicle of Different Animals
The document discusses how traditional Chinese medicine extracts may affect hair growth in animals but lacks detailed results.
research Human hair keratin hydrogel : fabrication, characterization and application
Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.
research Biology of the Hair Follicle: The Basics
The document concludes that understanding hair follicle biology can lead to better hair loss treatments.
research Complex Hair Cycle Domain Patterns and Regenerative Hair Waves in Living Rodents
Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
research Differential Auxin-Transporting Activities of PIN-FORMED Proteins in Arabidopsis Root Hair Cells
Different PIN proteins affect plant root hair growth by changing how auxin is transported.
research Elemental hair analysis: A review of procedures and applications
Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.
research Effects of EGF on the Morphology and Patterns of DNA Synthesis in Isolated Human Hair Follicles
EGF makes hair follicles grow longer but stops hair production.
research Ozone interactions with human hair: Ozone uptake rates and product formation
Ozone reacts more with unwashed hair, producing compounds due to scalp oils, which could lower ozone exposure but increase exposure to reaction products.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research The Ethnic Differences of the Damage of Hair and Integral Hair Lipid after Ultra Violet Radiation
Asian hair is more resistant to UV damage due to higher lipid content.
research Studies on the Proteome of Human Hair - Identification of Histones and Deamidated Keratins
Human hair contains diverse proteins, including keratins and histones, which could help assess hair health and aging.
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 Systematic approach to hair loss in women
