960-990 / 1000+ resultsresearch Cross‐linked features of mouse pelage hair resistant to detergent extraction
Two mouse mutants have defective hair cuticle cross-linking.
research Quantitation of normal human hair pigmentation by electron microscopy
Daily hair care may cause holes in hair fibers.
research Description of clinical aspects and microscopy of the hair shaft of a carrier of familial monilethrix
Monilethrix causes brittle hair and hair loss, and it runs in families.
research Targetoid Hair Regrowth Pattern in Alopecia Areata: A Case Series
A rare hair regrowth pattern can occur in some people with alopecia areata.
research Trichoscopic findings of trichotillomania: new observations
Trichoscopy is useful for diagnosing hair-pulling disorder.
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 Distribution of hairs in Chinese Han nationality
Chinese Han individuals have fewer hair follicles and hairs than Caucasians and Africans.
research Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research Interactions between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
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 Androgenetic Alopecia
The document concludes that signs of male and female pattern baldness include uneven hair thickness, yellow spots, skin discoloration around hair follicles, more thin and soft hairs, and many hair follicles with just one hair.
research Measuring Hair
Human head hair can grow very long and is thicker than most body hair.
research Short anagen hair syndrome: association with mono- and biallelic variants in WNT10A and a genetic overlap with male pattern hair loss
Some cases of short anagen hair syndrome are linked to specific genetic variations that are also connected to male pattern baldness.
research Upregulation of interfollicular epidermal and hair infundibulum β-catenin expression in Gsdma3 mutant mice
Mice with a Gsdma3 gene mutation have thicker skin and longer hair follicle openings due to increased β-catenin levels.
research Morphological and morphometric study of the androgenetic alopecic scalp using two- and three-dimensional analysis comparing regional differences
The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.
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 Orientation of Multi-Hair Follicles in Nonbald Men
Most nonbald men's multi-hair follicles are naturally positioned perpendicular to a line from the scalp's crown, which is important for natural-looking hair transplants.
research Naked Hair Shafts as a Marker of Cicatricial Alopecia
Naked hair shafts are significantly associated with scarring hair loss and may help diagnose it, especially when multiple are found.
research Linear alopecia areata
Alopecia areata can sometimes appear as a straight line of hair loss instead of round patches.
research Hair Matrix Cyst
Hair matrix cysts are rare skin nodules with unique features, often needing surgical removal.
research Trichoscopy findings in loose anagen hair syndrome: rectangular granular structures and solitary yellow dots
Rectangular black granules, solitary yellow dots, and mostly single-hair follicles suggest Loose Anagen Hair Syndrome.
research Light microscopy of the hair: A simple tool to "untangle" hair disorders
Light microscopy is useful for diagnosing different hair disorders.
research Study on Hair Distribution in Healthy Males for Hair Restoration Design
About 21.3% of young, healthy Chinese men experience hair loss. Hairlines are mostly linear or have a central protrusion. Hair is densest on the top and back of the head, and hair follicles usually have 1 or 2 hairs. This information can help in designing hair restoration procedures.
research Helical twist direction in the macrofibrils of keratin fibres is left handed
Keratin fibers in hair twist left-handed.
research A girl with loose anagen hair syndrome and concurrent uncombable hair syndrome
A girl had two rare hair conditions that helped understand their overlap.
research Histochemistry of the human hair follicle with consideration of anagen phases I to VI
Human hair follicles have a unique cell distribution and differentiation pattern during growth.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research Caucasian and Mediterranean Hair
Caucasian and Mediterranean hair is denser and varies in color and texture compared to African and Asian hair.
research Miniaturized hairs maintain contact with the arrector pili muscle in alopecia areata but not in androgenetic alopecia: A model for reversible miniaturization and potential for hair regrowth
Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.
