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 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

Isolated long hairs at the original hairline can help diagnose Frontal Fibrosing Alopecia.
research Characteristic microstructure of curved human hair
Curved human hair has different structures on its convex and concave sides.
research Cytochemistry of Trichohyalin Granules: A Possible Role for Cornification of Inner Root Sheath Cell in the Hair Follicle
Trichohyalin granules help inner root sheath cells in hair follicles harden by integrating with keratin filaments.
research Morphological changes of the hair roots in alopecia areata: A scanning electron microscopic study
Scanning electron microscopy revealed four distinct hair root shapes in alopecia areata, suggesting a less invasive diagnostic method.
research Trichohyalin: A structural protein of hair, tongue, nail, and epidermis
research Absence of vellus hair in the hairline: a videodermatoscopic feature of frontal fibrosing alopecia
Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.
research Hair Characteristics of East and Southeast Asians
East and Southeast Asians typically have less dense but thicker, straight black hair.
research Pattern hair loss: Assessment of microinflammation in miniaturized and terminal hair follicles through horizontal histologic sections
Microinflammation is more intense in smaller hair follicles and may be linked to hair loss.
research 1390 Active hair growth is fuelled by conveyor-belt like differentiation of germinative layer cells
Hair growth is driven by cells that move and change like a conveyor belt.
research Ultra‐structural hair alterations in F riedreich's ataxia: A scanning electron microscopic investigation
Friedreich's ataxia causes thin, weak hair with surface damage and cavities.
research Evaluation of Hair Density and Hair Diameter in the Adult Thai Population Using Quantitative Trichoscopic Analysis
Thai people's hair density decreases with age and varies by scalp area, but hair thickness stays the same regardless of age or scalp area.
research Isolation and Quantification of Glycosaminoglycans from Human Hair Shaft
Human hair contains more glycosaminoglycans in children than adults, and these compounds decrease with age, possibly affecting hair thickness.
research The Higher Number and Longer Duration of Kenogen Hairs Are the Main Cause of the Hair Rarefaction in Androgenetic Alopecia.
More kenogen hairs cause hair thinning in androgenetic alopecia, not hair miniaturization.
research Identification of factors contributing to phenotypic divergence via quantitative image analyses of autosomal recessive woolly hair/hypotrichosis with homozygous c.736T>ALIPH mutation
Different hair fiber development might explain why hair loss severity varies in patients with a specific genetic mutation, and treatments that thicken hair could help.
research NEWER FINDINGS ON THE ENZYMES AND PROTEINS OF HAIR FOLLICLES
research A Unique Type I Keratin Intermediate Filament Gene Family is Abundantly Expressed in the Inner Root Sheaths of Sheep and Human Hair Follicles
research Whisker hair (acquired progressive kinking of the hair): An indication for finasteride 1 mg?
Taking 1 mg of finasteride daily could potentially treat rare hair conditions like Acquired Progressive Kinking of the Hair and whisker hair.
research The Ultrastructure of Tissue Attached to Telogen Hair Roots
Recognizing specific tissue types on telogen hair roots can improve DNA typing.
research Structural Transition of Trichocyte Keratin Intermediate Filaments During Development in the Hair Follicle
research [Contribution to hair medulla study (author's transl)].
Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.
research 15. Hair and Nails
Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.
research 839 Spatiotemporal antagonism in mesenchymal-epithelial Signaling in sweat versus hair fate decision
Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.
research Keratins 1 and 10 or homologues as regular constituents of inner root sheath and cuticle cells in the human hair follicle.
Keratins K1 and K10 are found in the inner root sheath and cuticle of human hair follicles.
research Epithelial skirt and bulge of human facial vellus hair follicles and and associated Merkel cell-nerve complex
Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.
