Hair is made of strong keratin fibers that protect against the environment.
research Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Hair through the female life cycle
Women's hair generally gets thinner and less dense starting in their mid-thirties, with hair loss becoming more common as they age due to both genetics and environment.
research Oxidative stress in ageing of hair
Oxidative stress contributes to hair graying and loss as we age.
research Senile Changes of Dog Skin
Old dogs' skin thins, loses hair, and may darken, but doesn't show some human aging signs.
research Aging in the Male Face: Intrinsic and Extrinsic Factors
Male faces age with more wrinkles and hair loss, influenced by both body changes and environmental factors.
research Diffuse partial woolly hair in a patient with epidermolysis bullosa simplex with mottled pigmentation
A patient with a rare hair condition and skin disorder showed hair improvement after treatment.
research Tissue Mechanics in Haired Murine Skin: Potential Implications for Skin Aging
Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.
research Hair follicle aging is driven by transepidermal elimination of stem cells via COL17A1 proteolysis
Hair loss is caused by the breakdown of a protein called COL17A1 in hair follicle stem cells.
research Dynamic ultrastructural changes of the connective tissue sheath of human hair follicles during hair cycle
The connective tissue around hair follicles changes structure throughout the hair cycle.
research Patchy alopecia areata sparing gray hairs: a case series
Patchy alopecia areata can affect only pigmented hairs, leaving gray hairs untouched.
research Stress-sensing in the human greying hair follicle: Ataxia Telangiectasia Mutated (ATM) depletion in hair bulb melanocytes in canities-prone scalp
Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.
research Fracture in Hierarchical Biomaterials: Human Hair
Human hair's structure makes it tough and resistant to breaking.
research ESTROGEN RECEPTORS OF HAIRS BLACKS AND WHITES
Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.
research Exogen hair characterization in human scalp
The conclusion is that exogen is a unique hair cycle phase and the new sampling method specifically targets this stage, which may help in future hair loss research.
research Ageing processes influence keratin and KAP expression in human hair follicles
Aging causes changes in hair follicles, leading to weaker hair growth.
research Physiological changes in scalp, facial and body hair after the menopause: a cross-sectional population-based study of subjective changes
After menopause, some women lose scalp hair and gain facial hair, with patterns suggesting different underlying causes.
research Premature Graying of Hair
Premature graying of hair is common and stressful, but not well understood or treated.
research Hair Graying Regulators Beyond Hair Follicle
Hair graying is influenced by factors like nerves, fat cells, and immune cells, not just hair follicles.
research Mykogene und piläre Faktoren des Haarabbaus durch Dermatomyzeten* (2. Mitteilung)
