This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

This paper explores the diverse patterns and social significance of Black hair, approaching it as an art form, mathematical pattern, and ethnomathematic entity, and seeks to dispel myths while highlighting its vast possibilities.

Trichotillomania is a condition where people repeatedly pull out their hair, which can be triggered by stress and has various physical signs.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This commentary discusses the challenges of matrix effects in LC–MS analysis and introduces the concept of a matrix effect factor using stable isotopically labeled internal standards to improve analysis reliability.

This study documented a case where the medication baricitinib effectively promoted hair regrowth in a woman with alopecia areata but also led to an unexpected side effect of hypertrichosis, suggesting a need to further explore the JAK/STAT pathway's role in hair growth dynamics.

This study found that rubbing increased caffeine permeation into skin primarily via hair follicles, especially when applied against the natural hair direction.

This study demonstrated that a metric based on rotational echo intensity in 2H magic-angle spinning NMR can derive kinetic information for conformational exchange without complex modelling, achieving activation barriers consistent with prior findings.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This study found that rubbing significantly increased skin permeation of caffeine but not rhododendrol, with the direction of rubbing playing a crucial role in caffeine's enhancement.

Diphencyprone initially increases mouse hair growth, then slows it, possibly due to changes in specific protein levels.

This study suggests that minoxidil sulfate and pinacidil do not activate K channel currents in hair follicles, indicating their hair growth effects may occur through other mechanisms like increased blood flow.

This review discusses the hair eclipse phenomenon in hair cycling and the potential roles of synchronizers and microinflammation in its occurrence, reporting no new empirical findings.

This study introduces the concept of teloptosis, which influences hair shedding during the telogen phase and affects hair density, highlighting that early or delayed teloptosis has noticeable effects.

This study found that rubbing the skin increased caffeine permeation significantly, while rhododendrol showed no enhancement from rubbing, likely due to different distribution patterns in the skin layers.

This study found that the new HCC additive enhances the permeation of pigments and active ingredients into hair, suggesting potential use in developing functional cosmetic hair products.

This study found that exogenous EGF inhibited hair follicle development and decreased follicle density in both Tabby and normal mice, suggesting interactions between EGF and the Ta peptide influence normal skin phenotype.

This study investigated the dynamic mechanical properties of fluid-immersed elastic hair beds under oscillatory shear flows, revealing a nonlinear response influenced by driving frequency and amplitude, which impacts mechanosensory signaling stability in biological processes like vasodilation and ciliary remodeling.

This study found that hair follicle-plugging reduced skin permeation of certain model drugs, with effects varying based on EtOH pretreatment and the drug being evaluated.

This study found that integrating the Theory of Planned Behaviour with the Stimulus-Organism-Response framework improved the prediction of intentions to buy embarrassing products, with subjective norms being significant across drugstore, internet, and multi-channel environments.

This article analyzes various cases of weak or low-dose endocrine effects in laboratory animals and highlights challenges in data interpretation due to variability among controls, but reports no new experimental findings.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study found that TCDD significantly reduced EGF receptor binding in various animal models, linked to toxic symptoms like weight loss and developmental delays, with receptor phosphorylation persisting several days.

Finasteride and dutasteride's effects are mainly due to target binding saturation and slow enzyme turnover.

Finasteride's effectiveness measured by observing hair cortex changes using a cheap and easy method.

In this study, researchers found that progesterone promotes breast tumor growth in mice through its metabolite 5αP, which can be blocked by the 5α-reductase inhibitor finasteride.
