30 / 1000+ resultsresearch Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research External lipid function in ethnic hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
research Hair Histology and Glycosaminoglycans Distribution Probed by Infrared Spectral Imaging: Focus on Heparan Sulfate Proteoglycan and Glypican-1 during Hair Growth Cycle
Infrared spectral imaging can map hair growth proteins and sugars without staining.
research Effects of ultraviolet B radiation on physicochemical properties of human hair shaft
UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.
research Discrimination between basal cell carcinoma and hair follicles in skin tissue sections by Raman micro-spectroscopy
Raman micro-spectroscopy can help distinguish basal cell carcinoma from hair follicles in skin tissue.
research Analysis of cosmetic residues on a single human hair by ATR FT-IR microspectroscopy
Cosmetic residues on individual hairs can be identified and differentiated using ATR FT-IR microspectroscopy.
research Human Hair as a Testing Substrate in the Era of Precision Medicine: Potential Role of ‘Omics-Based Approaches
Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.
research Integral characterization of normal and alopecic hair at different degeneration stages by in-situ visible and chemical imaging
Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Proline-rich protein-like PRPL1 controls elongation of root hairs in Arabidopsis thaliana
A gene in Arabidopsis thaliana, AtPRPL1, affects root hair length but not cell wall composition.
research Keratin K15 as a Biomarker of Epidermal Stem Cells
Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.
research SCALP HAIR CHARACTERISTICS IN THE NEWBORN INFANT
Assessing newborn scalp hair can reveal important health information.
research Brain-targeted intranasal delivery of protein-based gene therapy for treatment of ischemic stroke
Intranasal delivery of gene therapy shows promise for treating ischemic stroke.
research Application of phytochemical screening and a combined FTIR spectroscopy and principal component analysis for effective discrimination of two varieties of Eclipta alba (L.) Hassk.
The two Eclipta alba varieties can be distinguished by their chemical differences.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Investigation of the cutaneous penetration behavior of dexamethasone loaded to nano-sized lipid particles by EPR spectroscopy, and confocal Raman and laser scanning microscopy
Nano-sized lipid particles increase dexamethasone's skin penetration and create a reservoir in the skin layers.
research Simultaneous RP-HPLC-DAD determination of dansyl amino acids in chemically treated human hair
A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.
research Penetration and Distribution in Human Skin Focusing on the Hair Follicle
Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
