Research
600-630 / 1000+ resultsresearch Adverse reaction to isotretinoin: alteration of the hair shaft structure
Isotretinoin can rarely cause hair to grow curly.
research Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Proliferating trichilemmal cyst with histological malignant transformation: Identification of hair sheath keratins in the tumor.
A hair cyst can become cancerous, showing specific keratins from the hair sheath.
research Curly hair: measured differences and contributions to breakage
Curly hair breaks more easily, especially with chemical treatments, but simpler grooming reduces breakage.
research Electron microscope observations on the glassy layer of the hair follicle*1
The glassy layer of hair follicles has different fibril sizes and arrangements in guinea pigs and young mice.
research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research A STUDY OF THE DIFFERENTIATION PRODUCTS OF THE HAIR FOLLICLE CELLS WITH THE ELECTRON MICROSCOPE.
Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.
research Understanding breakage in curly hair
Curly hair breaks due to mechanical damage and environmental factors, not chemical makeup, and needs ongoing care to prevent breakage.
research The Ziering Whorl Classification of Scalp Hair
The conclusion is that creating natural-looking hair restoration requires replicating natural scalp whorl patterns and inserting grafts at specific angles.
research Uncombable hair syndrome: A case presentation
Uncombable hair syndrome causes dry, frizzy hair that can't be combed flat, seen in a young child.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research High-voltage Electron Microscopy and 3-D reconstruction of human hair fiber ultrastructure
The research provided a detailed view of the non-keratinous parts of human hair fibers.
research Formation and Characterization of Hollow Microtubes by Thermal Treatment of Human Hair
Heating human hair creates hollow microtubes with smooth surfaces.
research Experimental Methods
Human hair's structure and properties were studied using advanced microscopes and mechanical tests.
research Mechanical characterization of curly hair: Influence of the use of nonconventional hair straightening treatments
Formaldehyde damages curly hair more than glyoxylic acid.
research Acquired progressive kinking of the hair following COVID‐19 disease
COVID-19 can cause hair to become progressively kinked.
research Quantifying hair shape and hair damage induced during reshaping of hair.
New imaging and testing methods can effectively assess hair shape changes and damage.
research Spontaneous Super-Contraction of Animal Hair
Animal hair can curl tightly on its own, especially in foxes, due to changes in keratin.
research The Cytology and Cytochemistry of the Wool Follicle
Wool follicles are complex, involving interactions between different cell types and structures.
research 성장기 모낭에서 큐티클층의 각질화 과정
The cuticle layer in hair follicles thickens during keratinization due to incomplete cytosol loss.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Collagen-type synthesis in human-hair papilla cells in culture
research When whorls collide: the development of hair patterns in frizzled 6 mutant mice
Hair follicles in mutant mice self-organize into ordered patterns within a week.
research "Curly" Wood and Tiger Tails
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research A case of congenital pili multigemini
A rare, harmless hair condition was found in an infant's eyebrow, needing no treatment.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research 1412 “Telescope model” for coordinated organ morphogenesis and stem cell formation
Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.
