This review discusses age-related and environmental factors affecting scalp hair changes in women, highlighting diagnostic complexities and ongoing research into targeted treatments, without reporting new clinical results.

Hair chromium levels might indicate chromium status and relate to glucose metabolism issues.

This study found no significant difference in serum levels of lead and selenium between patients with premature hair graying and those without it.

This study found that coloring white facial hair is an effective and feasible adjunct to intense pulsed light therapy for hair removal, with similar efficacy between using black eyeliner and black hair dye.

This study identified the c.1204G to A (p.E402K) mutation in the hHB6 gene as a cause of monilethrix in a Chinese family, highlighting the gene's role in the condition.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This letter to the editor discusses an observed case of hair repigmentation linked with etretinate therapy but reports no new research findings.

This study reports a case of GGCX syndrome in a 55-year-old Japanese male, characterized by PXE-like symptoms and coagulation deficiency, with an unreported phenotype of possible spinocerebellar degeneration.

This case study reports on a 72-year-old woman with frontal fibrosing alopecia and hair repigmentation, suggesting the rare occurrence of canities reversal could aid in diagnosing FFA.

Higher hair iron levels are linked to changes in brain structure and function.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.

This case report suggests that long-acting injectable risperidone may induce hirsutism in some patients, and clinicians should monitor for this potential side effect when prescribing this antipsychotic.

This study found that 448-kHz Capacitive-Resistive Electrothermal Therapy led to a significant increase in hair density in women with Female Pattern Hair Loss, likely due to stimulated proliferation of dermal papilla cells.

In this case report, a novel heterozygous mutation in the insulin receptor gene was identified in an adolescent girl with type A insulin resistance syndrome, characterized by excessive hair growth and skin changes, and her mother.

This study suggests that red deer stags provide a novel model for investigating hormonal regulation of hair growth due to the different cell growth rates in hair follicles during breeding and nonbreeding seasons.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

This study suggests that gamma-ray irradiation affects hair follicle density, structure, and pigmentation in mice, with some changes observed in later hair cycles.

This case study reported that a 15-year-old female developed acquired localized trichorrhexis nodosa, a hair shaft disorder, due to vigorous rubbing of an herbal powder on her scalp as part of local cultural practices.

This study found that inherited color dilution in Rex rabbit hair follicles is associated with DNA methylation changes, contributing to understanding the epigenetic regulation of rabbit pigmentation.

This study highlights the importance of recognizing artifacts in trichoscopy, as certain cosmetic products can mimic signs of early androgenetic alopecia.

In this study, Korean Red Ginseng showed protective effects against chemotherapy-induced premature hair follicle aging in an in vitro model by modulating specific cellular protein expressions.

This case report describes a 7-year-old girl who developed radiation-induced alopecia after a neurointerventional procedure, with dermoscopy revealing specific hair and scalp patterns that helped diagnose this rare complication. The findings highlight the importance of dermoscopy in distinguishing RIA from other alopecic disorders in children.

This case report describes the first known instance of alopecia associated with multicentric reticulohistiocytosis, evidenced by scalp biopsy findings of histiocyte infiltration in a 52-year-old woman.

This study identified complex regulatory elements and interactions involving the Hr gene and HR protein that are crucial for hair follicle formation and cycling in mammals.

This study characterized two siblings with hereditary vitamin D resistant rickets and a mutation in the vitamin D receptor, finding no immune-related disorders despite a defective T cell response to vitamin D.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This study describes a novel hairless mutant rat strain, F344-Hr(krh), developed via ENU mutagenesis, which provides a model for skin disease and potentially focal glomerulosclerosis due to specific genetic mutations.

This study reported that high-intensity red LED irradiation increased osteogenic differentiation and mineralization of human bone marrow mesenchymal stem cells, potentially through Wnt/β-catenin pathway activation.

In this study, red-light irradiation significantly increased hair follicle numbers and ATP levels in a mouse model, highlighting low-level laser therapy's potential to enhance hair regeneration and alter the skin metabolic microenvironment.

This letter reports repigmentation of hair in patients receiving latanoprost therapy.
