research Effects of Hormones and Endocrine Disorders on Hair Growth
Hormones significantly influence hair growth, with conditions like hirsutism and patterned hair loss linked to hormone levels; more research is needed for full understanding.
research Describing the Hair and Related Abnormalities
The document explains hair growth, hair loss types, and other hair-related terms.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research HAIR DISEASES
Most hair loss can be diagnosed with patient history and physical exam, and a few common types make up most cases.
research Impairment of autophagy may be associated with follicular miniaturization in androgenetic alopecia by inducing premature catagen
Impaired autophagy may cause hair loss by triggering early catagen.
research Hair Loss Physiology and Transplantation Principles
Hair loss is caused by hormonal changes that shorten hair growth phases and shrink hair follicles.
research Histopathologic prognostic factors for alopecia areata treated by intralesional corticosteroid
Certain scalp tissue features can predict how well alopecia areata responds to steroid injections.
research Histopathology of Hypotrichosis with Juvenile Macular Dystrophy
The research found that a specific gene mutation causes fewer hair follicles and disrupted hair growth cycles, leading to thin and short hair in people with Hypotrichosis with Juvenile Macular Dystrophy.
research Human papillomavirus vaccine recombinant quadrivalent
Two women lost hair after mesotherapy for hair loss, with one having permanent and the other temporary hair loss.
research The Histopathology of Noncicatricial Alopecia
Different types of hair loss have unique features under a microscope, but a doctor's exam is important for accurate diagnosis.
research Avaliação quantitativa em cortes histológicos transversais do couro cabeludo
The study found average numbers for different types of hair follicles in the scalp and observed differences between men and women, suggesting reasons for more common hair shedding in women.
research Differentiation of frontal fibrosing alopecia and Lichen planopilaris on trichoscopy: A comprehensive review
Trichoscopy helps tell apart Frontal Fibrosing Alopecia and Lichen planopilaris by showing different hair and scalp features.
research Scalp hair parameter changes in transgender individuals commencing gender-affirming hormone therapy: A 24-week prospective observational study
Feminizing hormone therapy increases hair counts and improves hair-related quality of life, while masculinizing therapy may reduce large terminal hairs.
research Analysis of Apoptotic Cell Death in Human Hair Follicles In Vivo andIn Vitro
Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.
research Hair Loss and Hirsutism Management
Low-level light therapy, possibly combined with other treatments, may become a leading hair loss treatment, while hirsutism often worsens with age and lacks preventive options.
research Cyclosporin A-induced hair growth in mice is associated with inhibition of calcineurin-dependent activation of NFAT in follicular keratinocytes
Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
research 840 Early and late matrix progenitors form the terminally differentiated cell layers of the hair follicle
Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.
research Expression of the L-Fucose Moiety on Infrainfundibular Follicular Keratinocytes of Terminal Follicles, Its Decreased Expression on Vellus and Indeterminate Follicles of Androgenetic Alopecia, and Re-Expression in Drug-Induced Hair Regrowth
Sugar molecule helps hair growth, less in balding, returns with treatment.
research Viable terminal scalp hair follicles constitute a necessary and sufficient biological end‐organ that conditions clinical efficacy of finasteride in males with male pattern hair loss without implying reversal of miniaturized follicles
Finasteride works for hair loss by maintaining existing hair follicles, not reversing miniaturization.
research Prolactin and Its Receptor Are Expressed in Murine Hair Follicle Epithelium, Show Hair Cycle-Dependent Expression, and Induce Catagen
Prolactin affects hair growth cycles and can cause early hair follicle regression.
research A Murine Model for Inducing and Manipulating Hair Follicle Regression (Catagen): Effects of Dexamethasone and Cyclosporin A
Dexamethasone speeds up hair loss in mice, while cyclosporin A slows it down.
research Control of Human Hair Growth by Neurotrophins: Brain-Derived Neurotrophic Factor Inhibits Hair Shaft Elongation, Induces Catagen, and Stimulates Follicular Transforming Growth Factor β2 Expression
Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.
research Dopamine is a novel, direct inducer of catagen in human scalp hair folliclesin vitro
Dopamine stops hair growth and pigment production in human scalp hair follicles.
research Characterisation of cell cycle arrest and terminal differentiation in a maximally proliferative human epithelial tissue: Lessons from the human hair follicle matrix
CIP/KIP proteins help stop cell division and support hair growth.
research Mycophenolate Antagonizes IFN-γ-Induced Catagen-Like Changes via β-Catenin Activation in Human Dermal Papilla Cells and Hair Follicles
Mycophenolate helps reverse hair loss effects caused by IFN-γ by activating a key hair growth pathway.
research Protective effect of Korean Red Ginseng against chemotherapeutic drug-induced premature catagen development assessed with human hair follicle organ culture model
Korean Red Ginseng may protect against hair loss caused by chemotherapy.
research Panax ginseng extract antagonizes the effect of DKK-1-induced catagen-ike changes of hair follicles
Panax ginseng extract may help prevent hair loss caused by DKK-1.
research Maintenance of optimised hair growth from viable terminal scalp hair follicles at baseline with oral finasteride in male pattern hair loss and first evidence of a “drug dependency” and a post-finasteride “rebound effect”.
Finasteride helps hair growth but stopping it causes faster hair loss.
research Penetration Profile of Microspheres in Follicular Targeting of Terminal Hair Follicles
Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.
