60-90 / 1000+ resultsresearch Update on detection, morphology and fragility in pili annulati in three kindreds
Careful light microscopy is crucial for detecting mild cases of pili annulati, which weakens hair and varies widely in expression.
research Pseudopili Annulati in a Dark‐Haired Individual: A Light and Electron Microscopic Study
A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.
research A hair abnormality in Abyssinian cats
Abyssinian cats can have a hair abnormality that makes their coat look rough and dull.
research Office Diagnosis of Hair Shaft Defects
The document explains how to identify different hair problems using a microscope.
research Epidermal cyst containing numerous spherules of keratin
The cyst had unusual keratin spherules and resembled bone marrow.
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 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 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 Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Evaluation of Surface Structure and Morphological Phenomena of Caucasian Virgin Hair with Atomic Force Microscopy
AFM can diagnose hair disorders by revealing detailed hair surface changes.
research Quisto matrical. Diagnósticos diferenciais.
The skin lesion was diagnosed as a matrical cyst with unusual features.
research Trichostasis Spinulosa
The study found clear differences in lesion distribution and microscopic features among trichostasis spinulosa, keratosis pilaris, and eruptive vellus hair cysts.
research Skin iconography analysis of traumatic anserine folliculosis: Skin image feature of TAF
TAF can be identified by excessive skin thickening and clogged hair follicles, helping distinguish it from similar skin conditions.
research Pili annulati with fragility: Electron microscopic findings of a case
The study found that hair fragility in Pili annulati may be caused by cavities and damage within the hair shafts.
research Trichothiodystrophy: an ultrastructural study of the hair follicle
Trichothiodystrophy causes abnormal protein deposits and distortion in hair follicles.
research Trichostasis Spinulosa
The document found differences in lesion distribution and microscopic features among trichostasis spinulosa and similar skin conditions.
research Banded Scalp Hair with an Unusual Glistening Appearance in a Teenager: A Quiz
A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.
research Nanoindentation of Hair Cortex and Medulla Regions
research Analysis of slenderizing human hair fibers surface morphology
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 "Curly" Wood and Tiger Tails
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research Structural abnormalities of the hair shaft
The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
research Hair Shaft Dysplasias
Hair shaft dysplasias are abnormal hair conditions that can be inherited or acquired and may signal other health issues, with limited treatment options available.
research Osseous Metaplasia and Mature Bone Formation With Extramedullary Hematopoiesis in Trichilemmal Cyst
Ossification in trichilemmal cysts is more common than previously believed.
research Microscopical characterization of known postmortem root bands using light and scanning electron microscopy
The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.
research 心音図の読み方の基礎 (心電図・心音図の価値と限界(特集))
Lichen spinulosus, usually seen in young people, can rarely occur in adults, as shown by a 52-year-old woman with a rough, bumpy rash.
research Characteristic microstructure of curved human hair
Curved human hair has different structures on its convex and concave sides.
