research Culture of the human pilosebaceous unit, hair follicle and sebaceous gland
The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.
research Natural Scalp Hair Regression in Preclinical Stages of Male Androgenetic Alopecia and Its Reversal by Finasteride
Finasteride reverses early hair loss and promotes growth.
research Novel cycle changes in scalp hair are caused by etretinate therapy
Etretinate therapy can cause hair loss by disrupting the hair growth cycle.
research Effect of ethosomal minoxidil on dermal delivery and hair cycle of C57BL/6 mice
Ethosomal minoxidil improves hair growth by penetrating deeper into skin and shortening hair cycle.
research Efficacy of low‐level laser therapy on hair regrowth in dogs with noninflammatory alopecia: a pilot study
Low-level laser therapy seems to help dogs with noninflammatory alopecia grow hair back.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research Permanent waving and hair straightening
Thioglycolate lotions are the most popular method for permanent waving and hair straightening.
research Pathobiology questions raised by telogen effluvium and trichodynia in COVID‐19 patients
COVID-19 may cause hair loss and scalp pain due to inflammation and changes in hair follicle receptors, but these symptoms typically resolve in 2 to 4 months.
research Exposure of Xenopus laevis tadpoles to finasteride, an inhibitor of 5-α reductase activity, impairs spermatogenesis and alters hypophyseal feedback mechanisms
Finasteride exposure harms tadpole reproduction and hormone balance.
research The Hair Shedding Visual Scale: A Quick Tool to Assess Hair Loss in Women
The new visual scale is a quick and effective way to measure hair loss in women.
research The usefulness of dermoscopy in canine pattern alopecia: a descriptive study
Dermoscopy is useful for diagnosing hair loss patterns in dogs.
research Successful Treatment of Temporal Triangular Alopecia by Hair Restoration Surgery Using Follicular Unit Transplantation
A 17-year-old boy with Temporal Triangular Alopecia successfully grew new hair after a hair restoration surgery using follicular unit transplantation.
research Alopecia Universalis Associated with Cutaneous T Cell Lymphoma
Some patients with a type of skin lymphoma can experience a rare, non-scarring hair loss that looks like another hair loss condition but has distinct features.
research Vellus hairs in the frontal scalp in early female pattern hair loss
More vellus hairs in frontal scalp indicate early female pattern hair loss.
research Inflammatory perifollicular fibrosis and alopecia
Inflammation around hair follicles leads to hair loss, and treatments should focus on reducing this inflammation and other factors for effectiveness.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research In Vitro Performance of Dutasteride-Nanostructured Lipid Carriers Coated with Lauric Acid-Chitosan Oligomer for Dermal Delivery
Dutasteride-loaded nanoparticles coated with Lauric Acid-Chitosan show promise for treating hair loss due to their controlled release, low toxicity, and potential to stimulate hair growth.
research Paracrine Secreted Frizzled-Related Protein 4 Inhibits Melanocytes Differentiation in Hair Follicle
A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.
research The diagnosis of androgenetic alopecia in children: Considerations of pathophysiological plausibility
AGA in children needs careful diagnosis due to low androgen levels and possible other causes.
research The Importance of Trichoscopy in Clinical Practice
Trichoscopy is a valuable tool for diagnosing and managing hair and scalp disorders.
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 Videodermoscopy does not enhance diagnosis of scalp contact dermatitis due to topical minoxidil
Dermoscopy can't help doctors identify scalp irritation caused by topical minoxidil.
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 Placebo‐controlled dose‐effect studies with topical minoxidil 2% or 5% in male‐patterned hair loss treated with oral finasteride employing an analytical and exhaustive study protocol
Minoxidil 5% works better than 2% for hair growth in male-patterned hair loss.
research Using automated microneedling with platelet rich plasma for treating cicatricial alopecia, recalcitrant alopecia areata and traction alopecia, case report
Microneedling with platelet-rich plasma can improve different types of hair loss.
research Androgenetic alopecia. Modelling progression and regrowth
AGA causes hair loss through follicle miniaturization and hair cycle changes; regrowth depends on anagen initiation in kenogen follicles.
research A Practitioner's Guide to Hair Loss Part 1—History, Biology, Genetics, Prevention, Conventional Treatments, and Herbals
The document concludes that hair loss is influenced by genetics and other factors, and while treatments like finasteride can help, they have limitations and side effects.
research Diagnostic Accuracy of Polarized and Ultraviolet Fluorescence-Induced Dermoscopy in Scarring and Nonscarring Alopecias: a Retrospective Observational Multicentric Study
UVF-dermoscopy is a useful tool for accurately diagnosing types of alopecia, especially in people with lighter skin.
research Rapunzel Alopecia: A Peculiar Form of Non-Marginal Traction Alopecia Secondary to Excessively Long Hair
