research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Exogenous and endogenous lipids of human hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research Effectiveness of blue LED in enhancing hair treatments: Analysis in different hair ethnicities
Blue LED light improves hair treatments for Caucasian and Asian hair but not for African hair.
research Investigating the relationship between the hair fiber proteome and hair quality
Hair quality is genetically determined and linked to its composition and strength.
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 Optical coherence tomography to evaluate the effects of oxidative hair dye on the fiber
Oxidative hair dye changes hair color and structure but doesn't weaken it.
research Structural analysis of human hair single fibres by scanning microbeam SAXS
Hair curliness is due to uneven distribution of different cortices within the hair fiber.
research Analyzing the laser-light reflection from human hair fibers Part1: Light components underlying the goniophotometric curves and fiber cuticle angles
Hair color affects light reflection, with black hair having higher cuticle angles and lighter hair showing less specular reflection.
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 Age, lifestyle and self‐perceptions of hair: Is there an association with hair diameter and tensile properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
research The Secrets of Beautiful Hair: Why is it Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research Elemental content of anagen hairs in a normal Caucasian population studies with proton induced X-ray emission (PIXE).
PIXE is an effective method to analyze hair's elemental composition.
research Nanomechanical characterization of human hair using nanoindentation and SEM

research Hair loss in women: medical and cosmetic approaches to increase scalp hair fullness
Female pattern hair loss can be treated with medications, surgery, and cosmetic products, considering its psychological impact.
research Fibrosing Alopecia in a Pattern Distribution (FAPD) in 16 African-Descent and Hispanic Female Patients: A Challenging Diagnosis
FAPD is a possible diagnosis for hair loss in patients of color and requires multiple evaluations for accurate diagnosis.
research Physical characterization of the hair of Mexican women
Mexican women's hair is between Asian and Caucasian hair in thickness and shape, with varied strength and some damage.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Role of Lipids in Water Permeation of Different Curl Pattern Hair Types
Lipid content and structure affect water absorption in different hair types.
research Novel Compounds for Hair Repair: Chemical Characterization and In Vitro Analysis of Thiol Cross-Linking Agents
APA is a promising new compound for repairing damaged hair, outperforming Olaplex® in strength and elasticity.
research Assessment of hair density and caliber in Caucasian and Asian female subjects with female pattern hair loss by using the Folliscope
Caucasian hair is denser, but Asian hair is thicker in female pattern hair loss patients.
research Penetration of cationic conditioning compounds into hair fibers: A TOF‐SIMS approach
The study found that certain conditioning compounds can penetrate hair and potentially improve its resistance to damage.
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 Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research Pigmented Hair-Thickening Fibers: A Camouflage Technique for Alopecia in Patients with Epidermolysis Bullosa
Colored hair-thickening fibers can help hide hair loss in some people with Epidermolysis Bullosa but may cause scalp irritation.
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 Stability of opiates in hair fibers after exposure to cosmetic treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
research Interactions between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
