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 The Microanatomy of Human Skin in Aging
Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research Intermolecular disulfide cross-linked structural change induced by permanent wave treatment of human hair with thioglycolic acid.
Permanent wave treatment with thioglycolic acid changes hair structure by altering disulfide bonds.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Morphological Changes of Human Hair Related to "Graying".
Gray hair affects hair's movement and appearance, making it less bouncy and more wavy.
research Histologic Changes in Seborrheic Keratoses after Rubbing
Rubbing seborrheic keratoses causes specific skin changes and may link them to hair follicles.
research Alopecia: histologic changes.
The review found that specific changes in scalp tissue can help diagnose different types of hair loss.
research Hair shaft abnormalities after chemotherapy and tamoxifen therapy in patients with breast cancer evaluated by optical coherence tomography
Chemotherapy can cause significant hair thinning and changes in hair texture, while tamoxifen has a smaller effect.
research Acquired morphological changes of mammalian hair scales
Mammalian hair scales change from smooth to wavy due to friction.
research Thermal Induced Changes in Cuticle and Cortex to Chemically Treated Hair
Heat worsens damage in chemically treated hair, especially bleached and straightened hair.
research Age-associated thin hair displays molecular, structural and mechanical characteristic changes
Older thin hair is not just thinner but also has different shape, structure, and stiffness.
research Non‐invasive evaluation of hair interior morphology by X‐ray microscope
X-ray microscopy can non-invasively show hair structure changes after treatments, but it's less detailed than TEM and needs improvement.
research Internal structural changes in age‐related curved hair due to cyclical extension: An IR spectroscopy study
Age-related hair curvature increases due to internal structural changes from grooming.
research Electron microscopic observation of skin and hair on a case of Netherton syndrome
Netherton syndrome causes specific skin and hair changes that help in early diagnosis.
research Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy
Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Features of structure of external layer of murine hair at different stages of malignant tumor development
Hair structure worsens as tumors grow in mice.
research CHANGES IN THE STRUCTURAL ELEMENTS OF THE SEBACEOUS HAIR FOLLICLE IN THE DIFFERENTIAL DIAGNOSIS OF NON-SCAR ALOPECIA
Thinner hair follicle structures are linked to non-scar alopecia.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research Age‐related changes in scalp biophysical parameters: A comparative analysis of the 20s and 50s age groups
Scalp conditions change with age, affecting hair health.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Ultra‐structural hair alterations in F riedreich's ataxia: A scanning electron microscopic investigation
Friedreich's ataxia causes thin, weak hair with surface damage and cavities.
research Changes in fibronectin, laminin and type IV collagen distribution relate to basement membrane restructuring during the rat vibrissa follicle hair growth cycle.
The rat vibrissa follicle can quickly remodel its basement membrane during hair growth, affecting cell signaling and activity.
research [Various changes in hair structure with different amounts of vitamin A in the diet].
research Expression of estrogen, androgen, and glucocorticoid receptors in recent striae distensae
Hormonal changes in skin may cause stretch marks.
research Structural change of keratin protein in human hair by permanent waving treatment
Permanent waving damages hair by disrupting its keratin structure.
research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research Changes in structure and geometric properties of human hair by aging
Older people's hair becomes less shiny because it gets more uneven and curved.
