600-630 / 1000+ resultsresearch Pulling force deforms hair follicle root sheath nuclei and surrounding dermal collagen matrix differently at infundibulum, isthmus and suprabulbar regions
Hair follicles respond differently to pulling forces in various regions.
research Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research Vibrissa hair bulge houses two populations of skin epithelial stem cells distinct by their keratin profile
There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

research Mechanism research of yak hair stretching slenderization based on the changes of conformation and cell shape
Yak hair stretches mainly due to macromolecules slipping past each other.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research Trichoscopy features of trichotillomania
Trichotillomania shows specific signs like black dots and uneven hair lengths but lacks certain features of alopecia areata.
research Isolation of intermediate filament assemblies from human hair follicles.
Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.
research Clinicopathological insights into the phenotypic variation of autosomal recessive hypotrichosis/wooly hair by c.736T>A LIPH mutation
The conclusion is that the variation in hair thinness in patients is mostly due to the amount of underdeveloped hairs, and treatments that thicken fine hairs might work for those with mild to severe conditions.
