720-750 / 1000+ resultsresearch Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
Hair proteins change location and structure as hair cells mature.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research Vesicle Formation and Follicular Root Sheath Separation in Mice Homozygous for Deleterious Alleles at the Balding (bal) Locus
A mutation in mice causes hair loss and skin issues due to a defect in a gene affecting cell adhesion.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
research Integral Lipid in Human Hair Follicle
The lipid in human hair follicles acts as a barrier, similar to the skin's lipid layer.
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 Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
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 Adhesion Failure of External Hair Cuticles Caused by Prussian Blue: Possible Electrochemical Roles of Sulfur and Cystine
Prussian Blue causes hair cuticles to detach, weakening the hair.
research Loose anagen hair syndrome
Loose anagen hair syndrome causes easily shed hair but usually improves with time.
research Central trichoptilosis with onycholysis
Hair splitting and nail detachment are linked conditions.
research Human hair follicle cells of outer root sheath maintain their genuine keratin expression in vitro
research Isolating Dermal Papilla Cells from Human Hair Follicles Using Microdissection and Enzyme Digestion
The method successfully isolates cells that are important for hair growth and could help study hair loss.
research Ultrastructure of the contrasting types of keratinization seen in the tail epidermis of the laboratory mouseMus musculus
Mouse tail skin has different keratinization near hair follicles and scales.
research Characterization of Hair Follicles in Hirosaki Hairless Rats with Deletion of Basic Hair Keratin Genes. Enlarged Medulla, Loss of Cuticle and Long Catagen
Hirosaki hairless rats have sparse, twisted hair due to missing hair keratin genes.
research Pili Trianguli et Canaliculi Is a Defect of Inner Root Sheath Keratinization
The hair defect is due to abnormal inner root sheath keratinization.
research Human hair keratins
research Cyclic Alopecia and Abnormal Epidermal Cornification in Zdhhc13 -Deficient Mice Reveal the Importance of Palmitoylation in Hair and Skin Differentiation
The enzyme DHHC13 is essential for healthy hair and skin, and its deficiency leads to hair loss and skin problems.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Vainas peripilares
The girl's "dandruff" was actually harmless hair casts, not a hygiene issue.
research Differential Expression of Genes Encoding a Cysteine-Rich Keratin Family in the Hair Cuticle
research The structure of hair and follicles of mice carrying the naked (N) gene

research Differential epithelial outgrowth of plucked and microdissected human hair follicles in explant culture
research A STUDY OF THE DIFFERENTIATION PRODUCTS OF THE HAIR FOLLICLE CELLS WITH THE ELECTRON MICROSCOPE.
Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.
research Failure of intercellular adhesion in hair fibers with regard to hair condition and strain conditions
Hair breaks differently when wet or dry and is affected by its condition and treatments like perms and bleaching.
research The disruption of Sox21-mediated hair shaft cuticle differentiation causes cyclic alopecia in mice
Disrupting the Sox21 gene in mice causes hair loss and regrowth cycles.
