A simple method can show hair's surface pattern.

This review explores keyword advertising in online advertising, noting its appeal due to audience reach and campaign optimization, but reports no new research data.

This study reports that hydrocolloid wound dressings emit energy capable of delaying evaporation in a potassium ferricyanide solution surrounding a hair follicle.

This study found that energy emitted by a hydrocolloid-based wound dressing fragment can penetrate glass and delay the evaporation of a Potassium Ferricyanide solution around a human hair follicle in vitro.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This study investigated the impact of container-tip design and hair density on the scalp delivery of minoxidil in topical formulations, finding that higher hair density reduced delivery, particularly with larger tip containers, indicating the importance of these factors in product design.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study reported that combining microdialysis and selective follicular closure with varnish significantly reduces caffeine penetration through hair follicles in an ex vivo porcine ear skin model.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

In this laboratory study, coffee bean residue extract was observed to promote the proliferation of human hair follicle dermal papilla cells by activating autophagy, showing potential for treating hair growth disorders and hair loss.

In preclinical studies, a B-Raf inhibitor called WYE-130600 caused dose-related skin effects in dogs and rats, suggesting potential similar responses might occur in humans.

In this study, applying case-only trees and random forests to a prostate cancer prevention trial revealed genotypes that may influence the efficacy of finasteride for prostate cancer prevention.

In a study on hair loss treatment, researchers found that a serum containing Cinchona succirubra extract and caffeine improved hair density and reduced hair loss in individuals with acute telogen effluvium after 16 weeks of use, with significant improvements observable after just 4 weeks.

This study reports that in vitro experiments suggest biomagnetic cross-talk between red blood cells and human hairs as a potential factor influencing RBC deformation.

In this study, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

This review discusses the hair growth mechanisms of minoxidil, suggesting both increased blood flow and a direct effect on hair follicles, but reports no new clinical results.

This study observed light flashes and repulsion effects in a single-slide preparation of human hair with a special solution, suggesting potential electromagnetic field emissions from the hair.

Finasteride modifies 5-alpha-reductases through a two-step process, affecting inhibitor potency and possibly causing side effects.

This study found that Edar signaling plays a role in regulating the hair cycle and apoptosis in hair follicle keratinocytes during the catagen phase in mice.

This study found that the combination of Stemoxydine® and Resveratrol improved hair density in women with Female Pattern Hair Loss.

This review describes the edge out punch for follicular unit excision, which may reduce follicle transection with its thicker walls and internal bevel design compared to other punch shapes, but reports no new clinical results.

This narrative review discusses various epidemiological study designs, the importance of reliable bias assessment tools, and the implications of database use for hypothesis testing in different research areas; it reports no new results.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study applies the Displacement Framework to explore how hair serves as both a biological and social signal, highlighting the costs of institutional demands for hair straightening in Black communities, which the natural hair movement counters by returning to natural hair.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This review discusses attempts to confirm low-dose effects in rodent endocrine studies and reports no findings; variability in control groups hinders demonstrating weak effects.

This study introduces a method using lentiviral delivery in mice to expedite analysis of factors crucial for hair follicle morphogenesis by enabling rapid gain- or loss-of-function studies.

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

This study found that electroosmotic flow through hair follicles significantly contributes to solution flow during iontophoresis in hairless mouse skin.

This study found that the "Trivedi Effect®" Biofield Energy Healing Treatment enhanced hair growth and melanogenesis in treated mice compared to untreated controls.
