research Chitosan stimulates root hair callose deposition and inhibits root hair growth
Chitosan slows root hair growth and causes a buildup of callose at low concentrations, but at high concentrations, it only inhibits growth without callose buildup.
research 1322 A non-cell autonomous dermal hedgehog signaling mechanism for follicular neoplasia and induction
Mutations in the SHH pathway in certain skin cells can cause skin tumors and abnormal hair growth.
research Bisphenol-A antagonizes the rapidly modulating effect of DHT on spinogenesis and long-term potentiation of hippocampal neurons
Bisphenol-A (BPA) increases connections between brain cells and boosts their activity, but it blocks the effects of a male hormone on brain cell plasticity.
research Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Delayed hair cycle in mnd2 mutant mice lacking HtrA2 serine protease activity
HtrA2 activity is crucial for normal hair growth by regulating fat cell development.
research Development of a stiffness‐angle law for simplifying the measurement of human hair stiffness
Hair stiffness increased by 13.2% after caffeine treatment, validating the Stiffness-Angle Law as an effective measurement method.
research BH03: Systemic sclerosis and frontal fibrosing alopecia: a novel combination of scarring alopecia
A woman with systemic sclerosis developed a unique scarring hair loss combining features of systemic sclerosis and frontal fibrosing alopecia.
research Polyphenol–Inorganic Sulfate Complex-Enriched Straightening Shampoo for Reinforcing and Restoring Reduced Hair Integrity
The shampoo straightens hair while keeping it healthy and less damaged.
research Commentary for Treatment of Thin Linear Scars on the Scalp
Double trichophytic closure effectively repairs thin scalp scars, reducing financial burden.
research Different synaptic stimulation patterns influence the local androgenic and estrogenic neurosteroid availability triggering hippocampal synaptic plasticity in the male rat
The availability of certain hormones and specific stimulation patterns affect long-term synaptic changes in the male rat brain.
research Hair and nail disorders
Hair and nail disorders can cause changes in scalp pigmentation, especially with sun exposure and alopecia.
research Smurf2-induced degradation of SMAD2 causes inhibition of hair follicle stem cell differentiation
Increasing Smurf2 hinders hair follicle stem cell differentiation and wound healing.
research The Ludwig pattern of androgenetic alopecia is due to a hierarchy of androgen sensitivity within follicular units that leads to selective miniaturization and a reduction in the number of terminal hairs per follicular unit
Ludwig pattern hair loss in women results from varying sensitivity in hair follicles, causing fewer visible hairs.
research Spink5-deficient mice mimic Netherton syndrome through degradation of desmoglein 1 by epidermal protease hyperactivity
research Novel modulatory effects of neurosteroids and benzodiazepines on excitatory and inhibitory neurons excitability: a multi-electrode array recording study
Neurosteroids and benzodiazepines reduce neuron excitability, with lasting effects on inhibitory neurons.
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 ENHANCING THE PHYSICAL CHARACTERISTICS AND SHELF LIFE OF RICE WATER (ORYZA SATIVA L.) GEL SHAMPOO: THE ROLE OF PROPYLENE GLYCOL CONCENTRATION
Propylene glycol concentration improves rice water gel shampoo's thickness and foam, extending its shelf life.
research A Missense Mutation in the Cadherin Interaction Site of The Desmoglein 4 Gene Underlies Localized Autosomal Recessive Hypotrichosis
A specific gene mutation causes sparse, brittle hair in a family.
research Hair perming via thiol‐Michael click reaction: A strategy to avoid oxidative damage
A new hair perming method avoids damage and lasts longer than traditional methods.
research Bullous Congenital Ichthyosiform Erythroderma with Tinea Capitis in Half-Siblings: Rare Phenomenon in Ichthyosis with Co-Existing Trichophyton rubrum Infection and Blocker Displacement Amplification for Mosaic Mutation Detection
Half-siblings with a rare skin condition improved with treatment for a fungal infection, but hair loss remained.
research Dynamic Behavior and Spontaneous Differentiation of Mouse Embryoid Bodies on Hydrogel Substrates of Different Surface Charge and Chemical Structures
Hydrogel surface properties affect mouse embryoid body differentiation.
research Female Androgenic Alopecia
Women with low SHBG levels and a high 3a-diol G to SHBG ratio are likely to experience female pattern baldness, possibly due to a slight excess of androgens affecting sensitive hair bulbs.
research MicroRNA-22-3p suppresses hair regrowth in androgenetic alopecia by targeting chloride intracellular channel 4
MicroRNA-22-3p hinders hair regrowth in male pattern baldness by affecting a specific protein.
research Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research Triphasic Progressive : une nouvelle formule pour une efficacité accrue contre la chute progressive des cheveux
Triphasic Progressive is more effective against hair loss.
research Maintenance effect of a once-weekly regimen of a Selenium Disulfide-based shampoo in moderate-to-severe scalp seborrheic dermatitis after initial treatment with topical corticosteroid/salicylic acid
Using Selenium Disulfide shampoo weekly helps prevent scalp dermatitis flare-ups.
