research Pharmacology of different progestogens: the special case of drospirenone
Drospirenone is a unique progestin with anti-water retention and potential blood pressure benefits, used in birth control and hormone therapy.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Quantifying the effects of repeated dyeing: morphological, mechanical, and chemical changes in human hair fibers
Repeated hair dyeing significantly damages hair.
research Impact of Hair Damage on the Penetration Profile of Coconut, Avocado, and Argan Oils into Caucasian Hair Fibers
Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.
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 A novel purification procedure for keratin-associated proteins and keratin from human hair
A new method effectively separates keratin-associated proteins and keratin from human hair.
research Location of keratin-associated proteins in developing fiber cuticle cells using immunoelectron microscopy
Keratin-associated proteins are part of the developing hair fiber cuticle.
research Fundamental studies on the interaction between moisture and textiles. Part X. Moisture sorption properties of wool and hair fibers.
Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research HAIR | Overview
The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.
research An updated review of the sebaceous gland and its role in health and diseases Part 1: Embryology, evolution, structure, and function of sebaceous glands
Sebaceous glands in our skin, developing during pregnancy and active in puberty, produce sebum for skin lubrication, temperature control, and fighting germs, also help in hormone regulation, and their dysfunction can cause conditions like acne and hair loss.
research Embryology, Histology, and Physiology of the Hair Follicle
The document explains how hair follicles develop, their structure, and how they grow.
research Convergent Evolution of Cysteine-Rich Keratins in Hard Skin Appendages of Terrestrial Vertebrates
Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.
research A discourse on human hair fibers and reflections on the conservation of drug molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research Experimental Methods
Human hair's structure and properties were studied using advanced microscopes and mechanical tests.
research Characteristic Microstructure of Curved Human Hair
Curved human hair has different structures on each side, which might cause its shape and is similar to wool.
research Science and Technology of Hair Fibers
The document concludes that understanding hair's composition and the effects of treatments can lead to better hair care products.
research 130 Deciphering the role of the hexosamine pathway in skin homeostasis
The hexosamine pathway helps maintain healthy skin by affecting the skin's structure and possibly increasing hair follicle stem cells.
research Comprehensive chemical, morphological, thermal, and biological characterization of Agave tequilana extract and chitosan-based dissolving microneedle arrays
Agave tequilana extract in microneedles affects their structure and bioactivity, showing potential for skin treatments.
research Retinoic-Acid-Related Orphan Receptor Alpha Is Involved in the Regulation of the Cytoskeleton of Hair Follicle Stem Cells
RORA affects hair follicle stem cells' structure and movement, potentially helping treat hair loss.
research 1439 Development of a complex skin organ in human induced pluripotent stem cell-derived organoids
Scientists created skin-like structures from stem cells that include features like hair and sweat glands.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Incorporation of hair follicles in 3D bioprinted models of human skin
3D bioprinting can now create skin with hair-like structures for medical use.
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 An examination of a strand of 30,000 and 70,000 year old mammoth hair
Mammoth hair from different ages shows distinct surface textures and elemental compositions.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Scarring Folliculitis in the Ectrodactyly-Ectodermal Dysplasia-Clefting Syndrome
The patient with EEC syndrome had scarring alopecia due to deep folliculitis, possibly linked to abnormal hair structure.
research Trichohyalin: Purification from Porcine Tongue Epithelium and Characterization of the Native Protein
Trichohyalin, a protein from pig tongue, was purified and found to have a filamentous structure.
