Manatee whiskers are specially adapted for touch in water.
research Characterization of hair follicles in Hirosaki hairless rats with deletion of basic hair keratin genes : enlarged medulla, loss of cuticle and long catagen
research Trichoscopic findings of androgenetic alopecia and their association with disease severity
Hair thickness differences help diagnose hair loss severity.
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 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 Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
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 Connexin 43 expression in the testes during postnatal development of finasteride-treated male rat offspring
Finasteride treatment changes Cx43 in rat testes, possibly causing fertility issues.
research Variations of scalp, pubic and axillary hair
Pubic hair is thicker than axillary and scalp hair, useful for forensic identification.
research Structural analysis of the outermost hair surface using TOF-SIMS with gas cluster ion beam sputtering
The hair's outermost surface has multiple layers of lipids and proteins.
research Expression and distribution patterns of spermine, spermidine, and putrescine in rat hair follicle
