Finding eosinophils near hair bulbs helps diagnose alopecia areata.
research A Hairy Paradox: Congenital Triangular Alopecia with a Central Hair Tuft
Some people with congenital triangular alopecia have a central tuft of hair in the bald patch, but the cause is unknown.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research Avaliação quantitativa em cortes histológicos transversais do couro cabeludo
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Characterization of hair follicles in Hirosaki hairless rats with deletion of basic hair keratin genes : enlarged medulla, loss of cuticle and long catagen

Hair growth drugs and epidermal growth factor do not change the calcium binding site gradient in hair follicles.
research 1030 EGFR protects the upper hair follicle from staphylococcus driven folliculitis
EGFR helps protect hair follicles from bacterial infections.
research Hox demarcates regional regeneration of adult hair follicle stem cells
Hox genes control hair follicle stem cell regeneration in different body regions.
research Characteristic intraepidermal nerve fibre endings of the intervibrissal fur in the mystacial pad of the rat: morphological details revealed by intravital methylene blue staining and the zinc iodide‐osmium tetroxide technique
Methylene blue staining effectively reveals detailed nerve structures in rat snouts.
research Comparison of two in vitro models for the analysis of follicular penetration and its prevention by barrier emulsions
Pig ear skin is better than human skin for testing how well barrier creams block allergens from entering hair follicles.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research Hair root characteristics of the human scalp hair in health and disease
Studying hair roots can help diagnose hair diseases and guide treatments.
research Parietal scalp is another affected area in female pattern hair loss: an analysis of hair density and hair diameter
Parietal scalp area has lower hair density and smaller hair diameter in women with hair loss.
research Viewpoint 4
Hidradenitis suppurativa may mainly affect vellus hair follicles, not terminal ones.
research INTRODUCING GAP IN HAIR FOLLICLE ELECTROMAGNETISM AS MECHANISM FOR THE PRESENCE OF BIPOLAR ELECTRICAL CHARGES INHERENT IN THE HUMAN HAIR SHAFT
Human hair has bipolar electrical charges because of a gap in the hair follicle's electromagnetic field.
research Diseases that Affect the Pinna
The document describes skin diseases affecting the outer ear in dogs and cats, their spread to other body parts, and treatment options.
research Radially patterned morphogenesis of murine hair follicle placodes ensures robust epithelial budding
research Genomic Characterization of the Human Type I Cuticular Hair Keratin hHa2 and Identification of an Adjacent Novel Type I Hair Keratin Gene hHa5
research Investigation of transfollicular caffeine penetration using microdialysis on ex vivo porcine ear skin
Caffeine penetrates skin quickly through open hair follicles, but less through closed ones, with levels becoming equal after 22 hours.
research Isolation of sensory hair cell specific exosomes in human perilymph
research Chiton integument: Ultrastructure of the sensory hairs of Mopalia muscosa (Mollusca: Polyplacophora)
research C‐tactile afferents: The mystery of human emotional touch has been hidden hair‐deep
C-tactile afferents are linked to emotional touch and social bonding through hair movement.
research The Immunohistochemical Changes of Skin during Hair Follicle Cycle after Depilation in Mice
Hair growth after depilation increases skin thickness, mast cell counts, and cell activity.
research ISID0192 - Three-dimensional ultra-high frequency ultrasound facilitates image processing to visualize microstructural changes of hair follicles and detects distinct disease phases of alopecia areata
3D-ultrasound can non-invasively detect and predict alopecia areata phases and outcomes.

Dermal papillae are crucial for hair growth and follicle development.
research Adipose Infiltration of the Dermis, Involving the Arrector Pili Muscle, and Dermal Displacement of Eccrine Sweat Coils: New Histologic Observations in Frontal Fibrosing Alopecia
The conclusion is that fat tissue in the skin is a new finding in Frontal fibrosing alopecia and may contribute to hair follicle and muscle degeneration.
research Interaction between dermal papilla cells and follicular epithelial cells in vitro: effect of androgen
Testosterone increases hair follicle cell growth when beard or axillary skin cells are present together.
