This article reviews various "white diseases" characterized by hypopigmentation or depigmentation and emphasizes the role of melanosomes in skin and eye color, but it does not present new clinical results.

This letter discusses a trichoscopic feature called the color-transition sign for differentiating between alopecia areata incognita and telogen effluvium, and reports no new clinical results.

This case report describes multiple skin tumors in an 11-year-old Doberman Pinscher with color dilution alopecia, but it remains unclear if the condition increases risk for such tumors.

This study found that dynamic resilient hyaluronic acid fillers were effective and well-tolerated for correcting moderate-to-severe nasolabial folds in people of color, with improvements in wrinkle severity and fewer adverse events compared to non-people of color.

This study observed that exosome treatment in skin led to increased dermal vascularity and mild inflammation, with one alopecia patient showing hair follicle growth at treated areas.

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 study found that hair dyed with anionic basic hair dye lost more color after shampooing compared to cationic and nonionic dyes, with alkaline shampoo increasing this effect.

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 discusses Dr. Swinehart's "Color Atlas of Hair Restoration Surgery," highlighting its usefulness as a comprehensive guide for planning and executing hair restoration, but notes it does not cover all controversies in the field.

This atlas graphically presents hair restoration surgery techniques through drawings and photographs, without reporting new clinical results.

This article reviews various aspects of diagnosing and treating alopecia, including medical and surgical therapies, without reporting new clinical results.

This study developed plant-pigment-based shampoos using extracts from Neem, Fenugreek, Hibiscus, and Butterfly Pea, which demonstrated stability, antimicrobial properties, and potential scalp benefits such as hair growth promotion and dandruff reduction, making them a promising alternative to synthetic dyes.

This review explores various theories of colorectal cancer stem cell biology and highlights the need for better identification and targeting of these cells to advance treatment strategies, but reports no new clinical findings.

In this case report, a patient with Cronkhite-Canada Syndrome developed colon cancer and liver metastasis despite hormone therapy, highlighting the need for regular monitoring and early detection strategies.

In this animal study, leaf extracts of Kalanchoe pinnata increased hair length in rabbits in a concentration-related manner, surpassing minoxidil at the highest concentration, though hair mass was unaffected.

In this study, a soy-containing diet significantly reduced the incidence of colonic polyps in mice compared to a soy-free diet, suggesting that soy foods might lower the risk of colon cancer development.

This study found that melatonin implants caused male weasels to molt, develop a new white winter coat, and become reproductively inactive, suggesting melatonin affects their neuroendocrine system.

This study identified more than 100 genetic loci associated with hair color variation in Europeans, explaining a significant portion of the trait's heritability and advancing understanding of hair pigmentation.

This study found that amphetamine was preferentially incorporated into black hair compared to white hair in Long-Evans rats, suggesting a role for drug basicity in hair color-based drug incorporation.

This review examines systemic drugs that can cause changes in hair color and emphasizes the importance of reporting these adverse events, but it does not include new clinical outcomes.

This study evaluated skin and hair color variations in different mouse strains, highlighting the association between hair cycle stages and skin pigmentation to better understand these features and their implications.

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 found that metabolite levels in hair samples differ significantly by hair color and segment, leading to recommendations for best practices in hair metabolomic studies.

This study found that both Japanese male and female hair darkens with age, with significant sex differences in melanin composition and melanosome morphology influencing hair color.

In this study, researchers found that the gene Dkk4 influences color pattern formation in domestic cat fetuses, and its mutation is linked to the Ticked pattern type.

In this study, researchers reported promising initial results in developing future cosmetic technologies that could transform hair styling by altering hair from within, offering alternatives to current methods.

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 found that pimozide, d-butaclamol, and pituitary pars intermedia grafts darken hair color in agouti C3H Avy mice, suggesting dopaminergic inhibition influences peptide-controlled hair color cycling.

This study investigated the genetic basis of coat color variation in cattle using skin transcriptome and whole-genome analyses, identifying the ASIP gene as a significant determinant that is differentially expressed and under strong positive selection in black and brown cattle breeds.

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.
