Research cited in this study

18 / 18 results

research Hormonal Effects on Hair Follicles

102 citations , July 2020 in “International journal of molecular sciences”

This review discusses the effects of hormonal changes on hair follicles, concluding that hormones like androgens and estradiol significantly influence hair growth and cycle, while the roles of other hormones are still being researched.

research A Case of Telogen Effluvium Associated with Drug-Induced Hyperprolactinemia

January 2020 in “Nihon rinsho hifukaikai zasshi”

This case study observed that discontinuing risperidone reduced elevated prolactin levels and improved hair thinning in a 77-year-old woman, suggesting risperidone-associated telogen effluvium as a consideration in similar cases.

research The Role of Vitamins and Minerals in Hair Loss: A Review

134 citations , December 2018 in “Dermatology and Therapy”

This review discusses the potential role of vitamins and minerals in managing non-scarring alopecia but reports no clinical results; the authors advocate for further controlled trials to explore these relationships.

research Short Communication: Temporal Changes in the Skin Morphology of Dairy Cows During the Periparturient Period

1 citations , April 2018 in “Journal of dairy science”

This study observed that hair follicle morphology in dairy cows changes during the peripartum period, with fluctuations in hair follicle width and anagen percentage but no overall marked changes in skin morphology parameters.

research Hair Cortisol Concentrations Are Associated With Hair Growth Rate

21 citations , January 2016 in “NeuroImmunoModulation”

This study found that daily hair washing was associated with significantly lower hair cortisol concentrations, suggesting it may influence the accuracy of using hair cortisol as a biomarker for chronic stress.

research The Postpartum Telogen Effluvium Fallacy

9 citations , January 2015 in “Skin appendage disorders”

This review found no significant evidence supporting postpartum telogen effluvium as a distinct condition, suggesting its incidence is uncertain and possibly negligible.

research A Role of Placental Growth Factor in Hair Growth

31 citations , February 2014 in “Journal of dermatological science”

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

research Hair Loss and Hyperprolactinemia in Women

19 citations , January 2012 in “Dermato-endocrinology”

This study suggests that moderate elevated prolactin levels are unlikely to cause significant hair loss in women, but still warrant further diagnostic investigation to rule out a prolactin-producing pituitary tumor.

research Hormonal Changes in Menopause: Do They Contribute to a Midlife Hair Crisis in Women?

38 citations , December 2011 in “British Journal of Dermatology”

This review discusses the influence of menopausal status on hair parameters in women without alopecia, finding significant differences in hair growth rate, percentage anagen, and hair diameter distributions, particularly in the frontal scalp.

research The Cell Membrane Complex: Three Related but Different Cellular Cohesion Components of Mammalian Hair Fibers

15 citations , May 2010 in “International Journal of Cosmetic Science”

This review discusses new developments in understanding the structure and properties of keratin fiber cell membrane complexes, without reporting new experimental results.

research From Telogen to Exogen: Mechanisms Underlying Formation and Subsequent Loss of the Hair Club Fiber

81 citations , April 2009 in “Journal of Investigative Dermatology”

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

research Hair: The Most Sophisticated Biological Composite Material

254 citations , January 2007 in “Chemical Society Reviews”

This review discusses the hierarchical structure and chemical properties of hair fibers and offers insights for chemists and biochemists, but reports no new experimental findings.

Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, Which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression

research Human Scalp Hair Follicles Are Both a Target and a Source of Prolactin, Which Serves as an Autocrine and/or Paracrine Promoter of Apoptosis-Driven Hair Follicle Regression

128 citations , March 2006 in “American Journal of Pathology”

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

research Scalp Hair Diameter Increases During Pregnancy

34 citations , August 2003 in “Clinical and Experimental Dermatology”

This study found that hair diameter increases toward the scalp during pregnancy, a novel observation compared to the normal decrease seen in nonpregnant women.

research Epithelial Barrier Function: Assembly and Structural Features of the Cornified Cell Envelope

425 citations , August 2002 in “BioEssays”

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice

research Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice

73 citations , June 2001 in “Endocrinology”

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

research Crosslinking Structure of Keratin: Number and Type of Crosslinks in Microstructures of Untreated and Potassium Cyanide Treated Human Hair

11 citations , September 1996 in “Journal of applied polymer science”

In this study, treatment with aqueous KCN selectively converted disulfide bonds to monosulfide crosslinks in hair, leading to changes in microstructural properties and rubberlike elasticity under specific laboratory conditions.

research The Histology of Keratin Fibers

56 citations , January 1977
