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
420-450 / 1000+ results research Human hair form. Morphology revealed by light and scanning electron microscopy and computer aided three-dimensional reconstruction.
Hair follicle shape determines hair type: curly, straight, or in-between.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research The Transverse Anatomy of Androgenic Alopecia
The study found that horizontal sections of scalp biopsies are better for analyzing hair loss, showing fewer hairs and more fine hairs in balding areas.
research Exogen Hairs in Women with and without Hair Loss
Women with and without hair loss have similar amounts of exogen hairs, so these hairs are not a key factor in hair loss conditions.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Proteomic Analysis of Single Hairs
Hair proteins are complex and provide valuable genetic and biological information.
research The Thinning Top: Why Old People Have Less Hair
Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.
research Structural analysis of the outermost hair surface using TOF-SIMS with gas cluster ion beam sputtering
The hair's outermost surface has multiple layers of lipids and proteins.
research Quantification of hair follicle parameters using computer image analysis: A comparison of androgenetic alopecia with normal scalp biopsies
Hair follicles are smaller in people with androgenetic alopecia compared to those with normal scalps.
research Quantitative Studies on Human Hair Growth(I). Fundamental Measurements and the Evaluation of Hair Growers.
Hair grows slower and thinner with age, but a test tonic improved growth in alopecia subjects.
research Characterization of a new tissue-engineered human skin equivalent with hair
research Trichoscopic evaluation of non-marginal traction alopecia: A case series
Long hair can cause hair loss in the middle of the scalp, and cutting it shorter helps.
research Clinical and instrumental characterization of hair and scalp aging in nonbalding Caucasian women
Aging significantly affects the hair and scalp of nonbalding Caucasian women, with changes that differ from male pattern baldness.
research Electron microscopy-image analysis: Quantification of ultrastructural changes in hair fiber cross sections as a
research Three‐dimensional imaging and analysis of the surface of hair fibres using scanning electron microscopy
The new 3D imaging method accurately measures hair surface details quickly.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research [Changes in telogen rate, hair density, hair diameter and rate of growth in androgenetic alopecia of the male. Simultaneously a contribution to the significance of dysplastic hair].
Frontal hair in male pattern baldness shows reduced growth and thickness.
research Trichoscopic findings of androgenetic alopecia and their association with disease severity
Hair thickness differences help diagnose hair loss severity.
research A morphometric and histologic study of the scalp in psoriasis. Paradoxical sebaceous gland atrophy and decreased hair shaft diameters without alopecia.
Psoriasis on the scalp causes smaller oil glands and thinner hair but doesn't lead to hair loss.
research Typisch androgenetische Alopezie?
Hair thinning on top of the head is common in female androgenetic alopecia.
research To be hairless or wise?
The protein hairless is important for hair regrowth because it stops the protein wise from blocking the hair cycle.
research “Cloned” Hairlines
Cutting and implanting hair follicles can create finer, more natural-looking hairlines, with about half of the implanted hairs growing back.
research Pili Annulati with Multiple Fragile Hairs
Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.
research Monilethrix unveiled by initial androgenetic alopecia.
An 11-year-old girl with hair thinning was diagnosed with monilethrix and early androgenetic alopecia.
research Diffuse Hair Loss
research Evaluating subjective versus objective measures of changes in hair density using standardized scalp photography
Dermatologists can accurately detect smaller differences in hair density than previously thought.
research DNA determination of human hair bulbs in normal and androgenetic alopecia
Hair loss happens due to faster cell growth and fewer cells in affected follicles.
research Dermoscopic Approach to a Small Round to Oval Hairless Patch on the Scalp
Dermoscopic examination helps diagnose different types of hair loss conditions by showing specific patterns.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
