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 Modeling Dynamic Hair as a Continuum
The authors created a realistic and efficient method to simulate hair movement by combining fluid dynamics with individual hair strand behavior.
research Acquired morphological changes of mammalian hair scales
Mammalian hair scales change from smooth to wavy due to friction.
research Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Fractography of human hair
Moisture content significantly affects how human hair breaks.
research Self-consistent field theory for the interactions between keratin intermediate filaments
Keratin filaments' elasticity is influenced by their terminal domains and surrounding medium.
research Measuring Hair
Hair conditioner makes wet hair easier to comb by reducing friction.
research Frictional Alopecia in a Child: An Uncommon Presentation of Lower Limb Hair Loss
A 6-year-old boy's leg hair loss was due to friction from sitting cross-legged, and it usually resolves on its own.
research Differential wetting characterization of hair fibers.
The new method can tell how hair fibers react to moisture after treatments.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
research Use of rotary echoes in 2 H
A new method accurately measures molecular movement without complex modeling.
research Hair surface interactions against different chemical functional groups as a function of environment and hair condition
Hydrophobic interactions affect virgin hair, while electrostatic interactions are key for bleached hair.
research Phenomenology of polymorphism: The topological pressure–temperature phase relationships of the dimorphism of finasteride
Finasteride's two forms have different stability based on temperature and pressure.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
research Spatial Probing of the Properties of the Human Hair Surface Using Wilhelmy Force Profiles
Human hair surface varies in wettability, showing daily and monthly patterns.
research Mechanism of Cuticle Hole Development in Human Hair Due to UV-Radiation Exposure
UV radiation damages hair by creating holes and peeling cuticle layers.
research Beyond the Follicle: Exploring Psychiatric Comorbidities in Androgenetic Alopecia
Androgenetic alopecia patients often experience higher rates of depression and anxiety, suggesting mental health screening before finasteride treatment.
research Responses of hair follicle–associated structures to loss of planar cell polarity signaling
Loss of Fz6 disrupts hair follicle and associated structures' orientation.
research Hair resistance to mechanical wear
Hair's resistance to wear varies by ethnicity and treatment, with less wear indicating stronger hair.
research Are hand preference and sexual orientation possible predicting factors for finasteride adverse effects in male androgenic alopecia?
Hand preference and sexual orientation may predict finasteride side effects in male hair loss.
research Assessment of styling performance in hair gels and hair sprays by means of a new two-point stiffness test.
The new stiffness test works well for gels but not for sprays.
research Picking a Side: Preferential Laterality in Scalp Hair Density
Some people grow more hair on one side of their scalp, possibly due to genetics, behavior, or environment.
research DTC pharmaceutical advertising: the debate’s not over
The debate on direct-to-consumer pharmaceutical ads continues, with consumers finding them educational and doctors concerned about their impact on patient relationships and medication understanding.
research Topical niacinamide does not stimulate hair growth based on the existing body of evidence
Niacinamide does not promote hair growth.
research Multifaceted role of hair follicle dermal cells in bioengineered skins
Human hair follicle dermal cells can effectively replace other cells in engineered skin.
research Metabolic Syndrome Prevalence in Psoriasis
People with psoriasis are more likely to have Metabolic Syndrome than those without psoriasis.
research Predicting hair cortisol levels with hair pigmentation genes: a possible hair pigmentation bias
Darker hair may lead to higher cortisol readings, suggesting a need to adjust for hair color in studies.
research Sleep Problems are Associated with Development and Progression of Lower Urinary Tract Symptoms: Results from REDUCE
Poor sleep is linked to a higher risk of developing and worsening urinary problems in men.
research An intergenerational androgenic mechanism of female intrasexual competition in the cooperatively breeding meerkat
Androgens in female meerkats influence aggression and dominance, affecting social dynamics and offspring behavior.
