Recognizing specific tissue types on telogen hair roots can improve DNA typing.
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 Trichoscopic Findings in Androgenetic Alopecia
Trichoscopy, a hair loss evaluation technique, found that people with Androgenetic Alopecia have more thin hairs, yellow dots, and perifollicular discoloration than healthy individuals.
research Expression Profiling and Cellular Localization of Genes Associated with the Hair Cycle Induced by Wax Depilation
Researchers found new genes involved in hair growth, which could help develop new hair treatments.
research Basal Lamina Changes During Tissue Interactions in Hair Follicles—An In Vitro Study of Normal Dermal Papillae and Vitamin A-Induced Glandular Morphogenesis
research Trichohyalin, an intermediate filament-associated protein of the hair follicle.
Trichohyalin is a protein in hair follicles that helps form hair filaments.
research Absence of vellus hair in the hairline: a videodermatoscopic feature of frontal fibrosing alopecia
Lack of small, fine hair on the front hairline is a key sign of frontal fibrosing alopecia.
research Upregulation of interfollicular epidermal and hair infundibulum β-catenin expression in Gsdma3 mutant mice
Mice with a Gsdma3 gene mutation have thicker skin and longer hair follicle openings due to increased β-catenin levels.
research Touch Receptors Undergo Rapid Remodeling in Healthy Skin
Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.
research Keratins 1 and 10 or homologues as regular constituents of inner root sheath and cuticle cells in the human hair follicle.
Keratins K1 and K10 are found in the inner root sheath and cuticle of human hair follicles.

research Focal atrichia: A diagnostic clue in female pattern hair loss
Focal atrichia helps diagnose female pattern hair loss.
research Biochemical Mechanisms Regulating Human Hair Growth
Androgens shorten hair growth phases, causing finer hair and more severe hair loss in men.
research Possible mechanisms of miniaturization during androgenetic alopecia or pattern hair loss
Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.
