This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This article describes a case of late-onset focal dermal elastosis in a 73-year-old woman, characterized by flat pale yellow lesions and increased normal elastic fibers, distinct from pseudoxanthoma elasticum.

Thick scalp melanoma can be hard to diagnose because it often looks like other skin conditions.

In this study, a case of a 20-year-old woman revealed ectopic acanthosis nigricans at a post-syndactyly-release surgical site, suggesting this rare condition could result from epidermal–dermal mismatch and altered growth factor signaling in grafted skin, without indicating any metabolic or malignancy concerns.

This study observed an unexpected case where a 44-year-old woman developed linear scalp pigmentation, resembling a tattoo, after undergoing a microneedling procedure followed by hair dyeing two days later, emphasizing the need to advise patients on avoiding hair dye application soon after such treatments.

This article discusses the challenges in hair follicle pigmentation research compared to epidermal melanocytes and highlights the limitations of relying on mouse models, but reports no new experimental findings.

This case report describes a unique occurrence of alopecia totalis resulting in pigmented hair growth over superficial scalp veins in an adult female using augmented betamethasone dipropionate ointment.

This study found that thymus transplantation in athymic mice resulted in T-cell-driven hair follicle depigmentation and loss, without multiorgan autoimmune disease, highlighting mechanisms of tissue-specific tolerance.

This study hypothesizes that postinflammatory hyperpigmentation in ashy dermatosis may result from basal cell apoptosis, as evidenced by consistent histologic findings across nine patients.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

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, Dguok deficiency in mice led to premature hair greying due to a loss of melanocyte stem cells and mature melanocytes, with increased oxidative stress and cell death; treatment with an antioxidant mitigated these effects, suggesting DGUOK's importance in hair pigmentation maintenance.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This study found that lentiginous melanoma had the highest incidence in central facial areas, with men showing higher rates on peripheral head regions and women on central face regions.

This study found that certain proteins linked to immune suppression and melanogenesis are associated with repigmentation in vitiligo patients undergoing standard treatment, suggesting these proteins and their pathways play roles distinct from merely reversing skin lesions.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This case report describes a 27-year-old female with systemic lupus erythematosus who presented with chilblain lupus erythematosus and melanonychia striata, emphasizing the rarity of such presentations in SLE patients.

This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

Vitiligo is caused by the immune system attacking skin pigment cells.

New insights in skin conditions show a complex link between certain moles and melanoma, improved hair loss treatments, and the need to identify different types of lupus.

This review discusses the complex etiology and pathogenesis of vitiligo, noting challenges in treatment effectiveness and relapse, and reports no new clinical results.

This study found that anagen stage protein homogenates and specific epitopes from melanogenesis proteins activated CD8 T cells, suggesting alopecia areata is an anagen-specific disease.

This study suggests that the structure and function of mouse melanocytes in the epidermis and hair bulb are influenced by genetic factors and local tissue environment, including hormones and growth factors.

This review discusses recent advancements in targeted therapies for vitiligo, including JAK inhibitors and mesenchymal stem cells, and highlights the need for further research.

This study observed that the development of the pars intermedia in long-tailed macaques is closely associated with changes in skin pigmentation during pre- and postnatal periods through melanocyte-stimulating hormone and ACTH activity.

This pilot study employed in-vivo multiphoton microscopy to visualize pigment-producing melanocytes in vitiligo patients, aiming to enhance understanding of treatment impacts and potentially improve transplantation therapies.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.
