90-120 / 1000+ resultsresearch 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 Fine structure of marsupial hairs, with emphasis on trichohyalin and the structure of the inner root sheath
Marsupial hair structure and keratin distribution are similar to placental mammals.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research Skin and hair regeneration after calciphylaxis. Histologic changes during formation and shedding of the calciphylactic carapace of the rat
After calciphylaxis, rats showed incomplete skin and hair regeneration, resembling scar tissue with fewer hairs.
research Eruptive vellus hair cyst syndrome or exuberant atypical keratosis pilaris?
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
research A histochemical examination of the epidermis of the southern elephant seal (Mirounga leonina L.) during the telogen stage of hair growth
The southern elephant seal's skin layer helps waterproof the skin by being tightly connected to hair shafts.
research Central trichoptilosis with onycholysis
Hair splitting and nail detachment are linked conditions.
research When whorls collide: the development of hair patterns in frizzled 6 mutant mice

research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Plica neuropathica: Bird's nest under dermatoscope
Plica neuropathica is a tangled hair condition that may be caused by hair damage or psychiatric issues and is treated by cutting the hair and addressing mental health.
research Functional redundancy of Frizzled 3 and Frizzled 6 in planar cell polarity control of mouse hair follicles
Frizzled 3 and Frizzled 6 together control the orientation of mouse hair follicles.
research Microstructure of Defective Mink Guard Hair
Defective mink guard hairs have split tips and missing cuticle cells, causing a metallic sheen.
research ‘Plica neuropathica’: Matting of Hair
A girl's severely tangled hair couldn't be fixed and had to be cut due to a rare condition called plica neuropathica.

Retinoids can help reduce keratin buildup in skin conditions.
research Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs
Trichography is important for diagnosing hair fragility in Pomeranian dogs with hair cycle issues.
research Pseudofolliculitis cutis: a vexing disorder of hair growth
Pseudofolliculitis cutis causes painful skin bumps and needs proper shaving and treatments to manage.
