research Evaluation of a new X-ray fluorescent analysis technique for the creation of a Nordic hair database: elemental distributions within the root and the virgin segment of hair fibers.
The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
research Volume Changes During Water Binding to Hair Fibers
Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
research The hair cycle and its regulation
Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.
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 Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Transcriptome Analysis of Improved Wool Production in Skin-Specific Transgenic Sheep Overexpressing Ovine β-Catenin
Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.
research Normal head-hair length is correlated with its diameter
Hair length and thickness are related, with thickness peaking at about a quarter of the hair's maximum length.
research Evaluation of Hair Density and Hair Diameter in the Adult Thai Population Using Quantitative Trichoscopic Analysis
Thai people's hair density decreases with age and varies by scalp area, but hair thickness stays the same regardless of age or scalp area.
research Hair density, hair diameter and the prevalence of female pattern hair loss
FPHL affects hair density and diameter, causing visible hair loss in older women.
research Hair Diameter Variation in Different Vertical Regions of the Occipital Safe Donor Area

research Hair diameter measurement methods: micrometer caliper versus phototrichogram
The phototrichogram is better for measuring hair thickness.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research Contribution of hair density and hair diameter to the appearance and progression of androgenetic alopecia in Japanese men
Hair thickness matters more than density for baldness in Japanese men over 25.
research Variation and Heritability in Hair Diameter and Curvature in an Australian Twin Sample
Hair diameter and curvature are mostly determined by genetics.
research Donor site of follicular unit excision hair transplantation: the relationship between appearance and actual hair density, and hair diameter
