330-360 / 1000+ results research Immunohistochemical analysis of tissue remodelling during the anagen—catagen transition of the human hair follicle
The inner root sheath is vital for hair follicle stability during growth changes.
research Age-Related Changes in Female Scalp Dermal Sheath and Dermal Fibroblasts: How the Hair Follicle Environment Impacts Hair Aging
Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.
research Ultrastructural abnormalities in the dermal papillae of both lesional and clinically normal follicles from alopecia areata scalps
Alopecia areata affects hair follicle structure, even in non-balding areas.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Faculty Opinions recommendation of Age-related changes in female scalp dermal sheath and dermal fibroblasts: how the hair follicle environment impacts hair ageing.
Aging affects the cells around hair follicles, which may influence female pattern hair loss and treatment options.
research Differences between ultrastructure and protein composition in straight hair fibres
Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.
research Nail changes in patients with graft-versus-host disease
Patients with graft-versus-host disease often have nail changes related to the nail matrix, with severity not linked to skin condition.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy
TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.
research Altered Dermal Fibroblasts in Systemic Sclerosis Display Podoplanin and CD90
Fibroblast changes in systemic sclerosis may help understand disease severity and treatment.
research Morphologic Markers of Acute and Chronic Stress in Child Abuse
The conclusion is that certain physical signs in the body can indicate past acute and chronic stress, which may help in child abuse investigations.
research Number changes and development potential of wool follicle cells in the early stages of fiber differentiation
Wool follicle cells are more complex than previously thought.
research Dermoscopic Findings and Their Therapeutic Implications in Trichostasis Spinulosa: A Retrospective Study of 306 Patients
Dermoscopy improves diagnosis and treatment planning for trichostasis spinulosa.
research Evaluation of hair surface structure and morphology of patients with lichen planopilaris (LPP) by atomic force microscopy (AFM)
AFM can help diagnose lichen planopilaris by identifying specific hair structure changes.
research Dynamic Plasticity of Axons within a Cutaneous Milieu
Hair clipping can trigger axon growth and changes in the skin.
research Expression of basement membrane components through morphological changes in the hair growth cycle
Fibronectin and other basement membrane components increase during hair growth and decrease during rest.
research A case of altered hair texture after resolution of alopecia areata
New hair after alopecia areata can be thinner and change color but usually keeps the same shape.
research Reviewer #4 (Public Review): Spatiotemporal dynamics of sensory neuron and Merkel-cell remodeling are decoupled during epidermal homeostasis
Sensory neuron remodeling and Merkel-cell changes in the skin happen independently.
research Skin signs of nutritional disorders.
Malnutrition causes skin changes due to nutrient deficiencies.
research Common genetic hair shaft abnormalities may be visualized by light and electron microscope
Genetic hair shaft abnormalities can be seen with microscopes and often affect scalp hair.
research [A three-dimensional observation of human hair tissue treated by modified trypsin-HC1 method].
The method allows detailed observation of hair tissue structures.

Chemical treatments weaken hair's thermal stability and structure.
research Study of normal hair and of some malformations with a scanning electron microscope
Hair malformations may occur due to timing issues in hair development.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Pulling force deforms hair follicle root sheath nuclei and surrounding dermal collagen matrix differently at infundibulum, isthmus and suprabulbar regions
Hair follicles respond differently to pulling forces in various regions.
research Structural changes in the trichocyte intermediate filaments accompanying the transition from the reduced to the oxidized form
Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
