research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.
research Inductive Properties of Hair Follicle Cells
Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.
research Unique Hair Properties that Emerge from Combinations of Multiple Races
Mixed-race individuals have hair with varied shapes and more root damage.
research Unusual patterns of presentation of frontal fibrosing alopecia: A clinical and trichoscopic analysis of 98 patients
Trichoscopy helps diagnose frontal fibrosing alopecia, even with unusual patterns.
research Faculty Opinions recommendation of Keratin 79 identifies a novel population of migratory epithelial cells that initiates hair canal morphogenesis and regeneration.
Keratin 79 cells help form and regenerate hair canals.
research [Changes in telogen rate, hair density, hair diameter and rate of growth in androgenetic alopecia of the male. Simultaneously a contribution to the significance of dysplastic hair].
Frontal hair in male pattern baldness shows reduced growth and thickness.
research Chronic telogen effluvium and female pattern hair loss are separate and distinct forms of alopecia: a histomorphometric and immunohistochemical analysis
CTE and FPHL are different hair loss types with unique causes.
research Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis
Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.
research Hair Follicle Stem Cells
Hair follicle stem cells can generate all hair cell types, skin, and sebaceous glands.
research A technique for more precise distinction between catagen and telogen human hair follicles ex vivo
Researchers developed a new method using methylene blue staining to more accurately identify the growth stage of human hair follicles.
research Recognition of the ultrastructure of the hair follicle of Cashmere goats under the transmission electron microscope
Recognizing ultrastructures of cashmere goat hair follicles helps identify and locate follicle layers.
research Hypotrichosis congenita of Marie Unna
A 54-year-old woman experienced progressive hair loss starting in adolescence, leading to sparse scalp hair and almost no eyebrows or eyelashes.
research Pigmented Casts
Pigmented casts are common in several hair loss conditions and can help diagnose specific types of alopecia.
research Growth of human hair follicle keratinocytes in vitro
The model successfully grew and differentiated hair follicle cells in the lab.
research Molecular Basis of Hereditary Hair Diseases
Certain gene variants can cause inherited hair diseases, which are important to diagnose and understand for patient care.
research Trichoscopy in Hair Shaft Disorders
Trichoscopy is a useful tool for diagnosing hair disorders without pulling out hair.
research Integral characterization of normal and alopecic hair at different degeneration stages by in-situ visible and chemical imaging
Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.
research Hair-cycle dependent differential expression of ADAM 10 and ADAM 12
ADAM 10 and ADAM 12 proteins are involved in different stages of hair growth and could be targets for treating hair disorders.
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 The Histopathology of Noncicatricial Alopecia
Different types of hair loss have unique features under a microscope, but a doctor's exam is important for accurate diagnosis.
research Androgenetic alopecia or fibrosing alopecia in a pattern distribution: When to perform biopsy in unusual cases?

A hair cyst can become cancerous, showing specific keratins from the hair sheath.
research Transient activation of β-catenin signalling in adult mouse epidermis is sufficient to induce new hair follicles but continuous activation is required to maintain hair follicle tumours
Temporary activation of β-catenin can create new hair follicles, but ongoing activation is needed to keep hair follicle tumors.
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.
