This report found follicular red dots in patients with scalp pigmentary disorders, suggesting they might be linked to the scalp's vascular structure and may have implications for conditions like discoid lupus erythematosus.

This review examines the pathogenesis of premature hair graying and potential treatment avenues, but reports no new experimental outcomes, highlighting ongoing research challenges and hopes for drug development.

This report describes two cases of sustained hair repigmentation related to porphyria cutanea tarda, though the underlying mechanism remains unclear.

In this study, hair color changes in piebald rats after skin grafting suggest that such changes are more likely due to the surgical process than the new environment.

In this study, researchers identified specific clinical and dermoscopic features of chronic radiation-induced dermatitis in 32 head and neck cancer patients treated with radiotherapy, and determined age, gender, and prior surgery as independent risk factors for developing this skin toxicity.

This article discusses a case of sudden hair whitening in an 82-year-old woman, exploring the 'overnight greying' phenomenon, and reports no new results.

This study found that red light accelerated the transition from the resting to growth phase in hair follicles faster than green and blue light in mice, suggesting it may stimulate hair growth.

This excerpt discusses website navigation and access details for JAMA Dermatology and reports no new research findings.

Minoxidil caused red hair to grow on a man's temples.

This study observed that the topical skin-whitening agent rhododendrol induced skin depigmentation in approximately 16,000 consumers, linked to melanocyte cytotoxicity and immune reactions.

This report describes a case of acquired trichorrhexis nodosa in a woman with severe iron deficiency anemia, highlighting a possible link between the two conditions.

This case report describes a six-month-old infant with focal scalp hair heterochromia and no detectable underlying abnormalities, which was still present at a one-year follow-up.

This case report describes a woman who developed green hair due to high copper levels in swimming pool water, exacerbated by hair treatments and inadequate water replacement.

Vitamin B12 deficiency can cause skin darkening and white hair, but it's reversible.

This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

This case report describes an elderly multiple myeloma patient whose hair repigmentation was associated with lenalidomide use, suggesting hair graying may be reversible.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

In this case report, the authors describe green hair discoloration in a patient attributed to the use of selenium sulfide.

This study highlights multiple factors contributing to hair graying, such as oxidative damage, melanocyte changes, and genetic influences, and suggests that repigmentation may be temporarily reversible, offering potential targets for future treatments while urging caution when applying mouse model findings to humans.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

This report describes a patient experiencing hair repigmentation linked to adalimumab therapy, a TNF inhibitor, a phenomenon not previously associated with this class of drugs.

Iron deficiency is not more common in women with hair loss, and neurogenic rosacea may need different treatment.

This study observed that estrogen receptor content was lower in white hair compared to black hair, with the lowest levels recorded in male white hair among participants aged 50-56.

This case report describes the unexpected hair repigmentation surrounding a scalp tumor in a 74-year-old man, suggesting a potential link between the carcinoma and changes in hair pigmentation.

This study found that hair dyeing is more common among Korean women than men and among individuals with significant grayness, and it was not linked to higher scalp disease prevalence.

This study found that nearly one in four young adults in a dermatology clinic had premature greying of hair, influenced by genetic factors, lifestyle, and micronutrient levels.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

This case report describes a patient with skin and nail hyperpigmentation and premature gray hair due to vitamin B12 deficiency, which were reversed after treatment with cyanocobalamin.

This study found that compromised antioxidant activity in gray hair follicles affects both mature melanocytes and their immature precursors, linked to down-regulation of melanogenesis-related genes.

Nilotinib may cause gray hair to return to its original color.
