This study found that using trait prevalence-informed priors may improve the prediction accuracy of appearance traits in Bayesian models, but their application is limited by sparse knowledge on trait prevalence.

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 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.

This study highlights the potential of forensic DNA phenotyping using Next Generation Sequencing to predict eye, hair, and skin color, aiding criminal investigations, though adoption faces challenges due to incomplete genetic understanding and ethical, social, and legal concerns.

According to this study, forensic DNA phenotyping using Next Generation Sequencing can reliably predict certain visible traits like eye, hair, and skin color, though its routine implementation in forensics is hindered by incomplete genetic knowledge and ethical concerns in some countries.

This study found that shampoos containing extracts from black bean, wheat, and rice bran enhanced hair growth activity and improved the physical properties of aged hair in laboratory models.

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.

This article reviews factors like hair and skin color that impact perceived age and suggests that lifestyle changes can make one look younger, but reports no new findings.

Black bean, wheat, and rice bran extracts can boost hair growth and improve hair quality.

This study introduces a novel method for capturing and digitally rendering the color appearance of physical hair samples using deep neural networks.

This study introduces a novel method for digitizing hair color that accurately captures and renders the color appearance of physical hair samples in synthetic images.

This review discusses recent advances in the understanding of follicular melanogenesis and its pathological changes, particularly how these changes are associated with specific disease phenotypes, but it reports no new results.

This study reported that keratin films lacking keratin-associated proteins showed different appearance, structure, and color deposit properties compared to conventional keratin films, suggesting potential for evaluating hair damage.

This case report describes a 1-year-old Yorkshire terrier presented with persistent alopecia and seborrhea in dark-haired areas, with no signs of hair regrowth despite treatment for folliculitis and seborrhea.

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.

In this study, both radiofrequency microneedling and ultrasound treatments with a plant-based secretory factor hair serum enhanced hair and scalp health in subjects with androgenetic alopecia, with ultrasound showing more pronounced improvements in hair appearance, density, and color.

This study found that acetyl zingerone methyl ether (MAZ) in hair dyes and haircare products may reduce oxidative damage, improve hair condition, and enhance the longevity and quality of dyed hair color.

This review summarizes advancements in forensic DNA phenotyping for appearance, ancestry, and age prediction from crime scene samples, reporting no new research findings but highlighting areas needing further research and validation.

In this study, an ammonia-free and PPD-free permanent hair dye was tested on 50 ethnically diverse females, showing no cases of contact dermatitis and significant improvements in hair shine, color, moisturization, porosity, and combability after two dyeing sessions.

This study found that Swiss cattle exhibiting rat-tail syndrome are heterozygous for genetic variants linked to pigmentation and color dilution, likely due to Holstein introgression in the Simmental breed.

This review discusses scalp micropigmentation (SMP) for camouflaging baldness and reports no new clinical results; it aims to highlight SMP's cosmetic benefits and practical advantages over surgical hair transplantation.

This article discusses patient selection and procedural design for hair transplant surgery without reporting new clinical results; it also considers how hair transplant designs can align with various hairstyles.

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 review discusses the processes contributing to hair and scalp aging, noting oxidative stress as a key factor, and reports no new clinical findings.

This review highlights microneedling's promise as an adjuvant therapy for enhanced drug delivery in dermatology, especially for conditions like atrophic scars and pigmentation disorders, though its efficacy for vitiligo is limited.

This study examined the use of medical dermapigmentation to restore lip appearance after traumatic injuries, finding that a staged approach effectively camouflages scar tissue, enhances symmetry, and improves psychological well-being, demonstrating benefits in a clinical case of a dog bite.

Microneedling improves the appearance and feel of post-burn scars.

Hair care products are important for appearance and self-esteem, and choosing the right ones can help maintain healthy hair.

This study reported that partial longitudinal follicular unit transplantation improved eyebrow appearance and patient satisfaction without visible scarring, making it a reliable method for eyebrow restoration.

This study found that pigmented hair-thickening fibers improved the appearance of scalp alopecia in patients with epidermolysis bullosa, although they may cause pruritus and should be used cautiously.
