This article reviews the side effects of topical latanoprost therapy, particularly the hypertrichosis and pigmentation changes of eyelashes and nearby skin, and reports no new clinical results.

Pilocarpin can cause hair regrowth and color change in some cases but not in others, and it may have side effects in animals.

This article discusses how the brain's neural circuits evaluate skin aging to judge social standing and suggests that people often attempt to deceive themselves and others about their true age.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This guide provides a comprehensive approach to diagnosing periocular hair disorders, which can range from benign conditions to those posing serious health risks.

This study found that water extracts of Spondias mombin bark led to significant recovery in rats with induced cancer, while alcohol extracts did not produce significant effects.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

This review discusses the adverse effects on hair associated with targeted cancer therapies and reports no new clinical results; it emphasizes the need for comprehensive documentation of these effects.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study reported that a low color temperature light (1900 K) may have positive effects on melatonin secretion, eye protection, wound healing, and hair regeneration compared to higher temperature lights.

This review found that while forensic DNA phenotyping and health applications for pigmentation genetics show potential, factors like phenotype definition and population diversity present challenges to accurate genotype-to-appearance predictions.

This study found that integrating machine learning enhances the predictive accuracy of forensic DNA phenotyping from low template DNA, achieving high accuracy for traits like eye color, although challenges remain for admixed populations and complex traits.

DNA can predict physical traits like eye and hair color accurately, especially in Europeans, but predicting other traits and in diverse populations needs more research.

This study found that bimatoprost eye drops increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits, without causing inflammation.

This study found that bimatoprost eye drops significantly increased eyelash length, thickness, pigmentation, and the number of eyelashes per follicle in rabbits within one month.

In this study, researchers used computer-generated models to demonstrate that subtle changes in hair diameter, density, and style significantly affect perceptions of age, health, and attractiveness.

In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.

This study reviews drug-induced hair changes, noting that hair loss often reverses after stopping the drug, but permanent alopecia cases post-chemotherapy are rising.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

Fear of hair-related issues causes significant mental distress, especially in high-stress women.

This review summarizes the ophthalmic complications of common periocular aesthetic treatments but reports no new clinical findings, emphasizing the importance of recognizing potential side effects.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

This article presents an overview of uncombable hair syndrome, emphasizing its clinical and molecular characteristics and noting systemic manifestations such as neuropsychiatric, ophthalmic, and cardiopulmonary issues.

In this study, primary cilia were found to contribute to meibomian gland enlargement and lipid production, though they are not necessary for normal gland development.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.
