research Secretory phospholipase A2-IIA overexpressing mice exhibit cyclic alopecia mediated through aberrant hair shaft differentiation and impaired wound healing response
Mice with too much sPLA₂-IIA have hair loss and poor wound healing due to abnormal hair growth and stem cell depletion.
research Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Existence of various structural zones in keratinous tissues revealed by X-ray microdiffraction
Keratinous tissues have multiple structural layers, including ordered keratin and lipid granules.
research Acidic and basic hair/nail ("hard") keratins: their colocalization in upper cortical and cuticle cells of the human hair follicle and their relationship to "soft" keratins.
Hair and nail cells share similar proteins, indicating a common differentiation pathway.
research Red Ginseng Extract Promotes the Hair Growth in Cultured Human Hair Follicles
Red Ginseng Extract may help human hair grow by activating growth pathways and blocking negative effects of certain hormones.
research Thyrotropin-releasing hormone and oestrogen differentially regulate prolactin and prolactin receptor expression in female human skin and hair follicles in vitro
Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.
research 15-deoxy prostaglandin J2, the nonenzymatic metabolite of prostaglandin D2, induces apoptosis in keratinocytes of human hair follicles: a possible explanation for prostaglandin D2-mediated inhibition of hair growth
A substance called 15-deoxy prostaglandin J2 can cause hair follicle cells to die, which might explain how prostaglandin D2 can lead to hair loss.
research Incorporation of Isotopically Labeled Cocaine and Metabolites into Human Hair: 1. Dose-Response Relationships
Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.
research Localisation and regulation of cholesterol transporters in the human hair follicle: mapping changes across the hair cycle
Cholesterol transport in hair follicles decreases from growth to regression phase.
research Knockdown of FOXA2 Impairs Hair-Inductive Activity of Cultured Human Follicular Keratinocytes
Reducing FOXA2 in skin cells lowers their ability to grow hair.
research Hair care practices and their association with scalp and hair disorders in African American girls
Certain hairstyles and less hair oil use in African American girls can lead to scalp conditions like traction alopecia and seborrheic dermatitis.
research Methods for the isolation and 3D culture of dermal papilla cells from human hair follicles
The document describes a way to isolate and grow human hair follicle cells in 3D to help study hair growth.
research The Thyroid Hormone Analogue KB2115 (Eprotirome) Prolongs Human Hair Growth (Anagen) Ex Vivo
KB2115 (eprotirome) can safely extend the hair growth phase without damaging cells or changing hair color.
research A simple method using ex vivo culture of hair follicle tissue to investigate intrinsic circadian characteristics in humans
Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.
research Ultrastructural immunolocalization of involucrin in the medulla and inner root sheath of the human hair
Involucrin helps strengthen the inner parts of human hair.
research Noninvasive method for assessing the human circadian clock using hair follicle cells
Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.
research Age, Health and Attractiveness Perception of Virtual (Rendered) Human Hair
Hair style affects perceptions of age, health, and attractiveness more than hair color does.
research Establishment of an in vitro organoid model of dermal papilla of human hair follicle
Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.
research Hair Keratin Associated Proteins: Characterization of a Second High Sulfur KAP Gene Domain on Human Chromosome 2111In fond memory of Dr Peter Steinert.
A second domain of high sulfur KAP genes on chromosome 21q23 is crucial for hair structure.
research The Phytocannabinoid (–)-Cannabidiol Operates as a Complex, Differential Modulator of Human Hair Growth: Anti-Inflammatory Submicromolar versus Hair Growth Inhibitory Micromolar Effects
CBD can either reduce inflammation and not affect hair growth at low levels or inhibit hair growth at high levels.
research Demethylation of methionine and keratin damage in human hair
Copper and iron cause keratin damage in hair by converting methionine to homocysteine.
research Expression patterns of the glial cell line–derived neurotrophic factor, neurturin, their cognate receptors GFRα-1, GFRα-2, and a common signal transduction element c-Ret in the human skin hair follicles
Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.
research Clinical Study to Evaluate Safety and Efficacy of a Topical Hair Minimizing Lotion in Healthy Human Volunteers
The lotion safely and effectively reduces unwanted hair growth.
research Annurca Apple Nutraceutical Formulation Enhances Keratin Expression in a Human Model of Skin and Promotes Hair Growth and Tropism in a Randomized Clinical Trial
