research Clinical, Microscopic and Ultrastructural Findings in a Case of Short Anagen Syndrome
The study found that Short Anagen Syndrome results in short hair growth not due to hair fragility, and hair may grow longer after puberty.
research Photodegradation of hair of different ethnicity after 1 year of exposure to natural weathering in Arizona
Hair with more melanin resists weather damage better.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research Central trichoptilosis with onycholysis
Hair splitting and nail detachment are linked conditions.
research Photoaggravation of hair aging
Sunlight exposure ages hair, making it brittle, stiff, and dry.
research Skin diseases
Skin ages and changes due to sun, wind, and aging, causing dryness, thinning, and hair loss.
research Cell death by cornification
Cornification is how skin cells die to form the protective outer layer of skin, hair, and nails.
research Hair weathering and hair capacitance mapping: a pilot study
Hair capacitance mapping effectively measures hair surface moisture changes.
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 Cornification
Cornification is the process where living skin cells die to create a protective barrier, and problems with it can cause skin diseases.
research The structure of the cornified claw sheath in the domesticated cat (Felis catus): implications for the claw‐shedding mechanism and the evolution of cornified digital end organs
Cat claws stay sharp by shedding their outer layer through microcracks formed during activities.
research Weathering of hair in trichoteiromania
Her hair grew back normally after she stopped rubbing it.
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 Evidence for biological shaping of hair ice
A fungus is essential for forming and shaping hair ice on dead wood.
research The susceptibility of disulfide bonds to modification in keratin fibers undergoing tensile stress
Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.
research The case of the felted wig
The hairpiece matted due to weathered hair after shampooing.
research Changes in the nail plate of the elderly
Old people's nails often have problems due to body changes, more diseases, and self-care difficulties, affecting their movement and hand use.
research Studies on the change of the calf-skin during the process
Soaking calf skin in lime solution dissolves cells at different rates, with optimal dehairing after 4-7 days.
research Keratinization of sheath and calamus cells in developing and regenerating feathers
Feathers become harder as they develop due to a change in keratin type.
research Thermal and mechanical transitions in keratins and their relevance for hair cosmetics
High temperatures and cosmetic processes can damage hair keratin, affecting its structure and strength.
research 575 Senescent atrophic epidermis retains Lrig1+ stem cells and loses Wnt signaling, a phenotype shared with CD44KO mice
research Skin, Genetic Defects, and Aging
Genetic defects and UV radiation cause skin damage and aging.
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 Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties
UV radiation damages hair similar to bleaching, but double bleaching causes more severe protein degradation.
research Characterization and causal investigations of an alopecia syndrome in Australian fur seals (Arctocephalus pusillus doriferus)
Young female Australian fur seals are losing hair due to low tyrosine and zinc levels and high pollution exposure.
research 3P343 Change of cell membrane complex of a hair fiber caused by hair damage
Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.
research Key locations of oxidative damage in human hair keratins after heat and ultraviolet light exposure
Heat and UV exposure damage hair structure by altering keratins.
research Reduced cell cohesiveness of outgrowths from eccrine sweat glands delays wound closure in elderly skin
Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.
