In this study, researchers found no significant differences in vitamin B12, folate, and homocysteine metabolism between patients with alopecia areata and controls, suggesting no association with vitamin B12 deficiency.

This study suggests no significant association between vitamin D receptor gene polymorphisms and alopecia areata.

This review discusses inherited forms of vitamin D-dependent rickets and explains their genetic and metabolic causes but reports no new clinical findings.

In this study, researchers observed that the success of treating hereditary vitamin D–resistant rickets in children depends on the mutation location in the VDR gene, notably with favorable dental development outcomes for those with the p.R391S mutation, despite persistent alopecia.

This study examines how the Severity of Alopecia Tool score was used to assess Alopecia Areata in patients while excluding systemic conditions that might affect vitamin D levels, but reports no new clinical results.

This study found that in young male rats, cortisone acetate inhibited body growth and caused alopecia, which vitamin B12 and aureomycin largely counteracted, especially when combined.

This study found that adding vitamin A to the diet improved hair follicle density and fur quality in heat-stressed Rex rabbits, involving specific signaling pathways.

This study found that centrifugally spun scaffolds with higher concentrations of platelet-derived bioactive molecules enhanced melanocyte metabolic activity and proliferation, suggesting potential for improving vitiligo treatment.

This study found that the absence of vitamin D receptor-mediated suppression of PPARγ expression causes hair loss in VDR-null mice.

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 meeting report provides an overview of recent evidence on vitiligo treatments, indicating a lack of standardized outcome measures and emphasizing the need for more consistent clinical trials.

This review explores how vitamin D3 analogs could target various skin processes and diseases, potentially offering selective and effective treatments beyond psoriasis, but reports no new clinical findings.

This study demonstrated that high doses of L-cystine and vitamin B6 effectively prevent doxorubicin-induced hair loss in mice.

This study found that iron deficiency anemia is a key factor in the development of telogen effluvium, and higher 25-hydroxyvitamin D3 levels in TE patients may be linked to increased UV exposure.

In this study, researchers found that Langerhans' cells likely do not play a role in the depigmentation process in C57Bl/Ler-vit.vit mice, as their number was normal during depigmentation and highest afterward.

This review explores the shared pathogenesis of alopecia areata and vitiligo and compares treatment responses, noting that hair regrowth in alopecia areata occurs more rapidly than skin re-pigmentation in vitiligo, possibly due to differences in stem cell biology and treatment effects on melanocytes.

This review discusses the role of the unliganded vitamin D receptor in hair follicle cycling and tumor formation in mice and reports no new experimental findings.

This study found that the prevalence of vitiligo in Germany is higher in clinical exams than in claims data, suggesting many patients may not seek medical help due to unsatisfactory treatment options.

This case report observed that while a 4-year-old boy with vitamin D-dependent rickets type II showed biochemical and bone improvement after vitamin D and calcium treatment, his alopecia did not improve.

This study found that using conditioned medium from vitamin D3 pre-activated preadipocytes enhanced hair regeneration in mice by promoting angiogenesis.

This study observed higher rates of H. pylori infection in vitiligo patients compared to those with telogen effluvium, though no significant association was found with vitiligo disease activity or pattern.

This study on a 30-year-old male reported that single-hair follicular unit transplant effectively repigmented a stable vitiligo patch, achieving complete pigmentation in 8 weeks with no recurrence after 6 months.

Vitamin D3 may prevent hair loss from chemotherapy, but side effects and cancer cell protection are concerns.

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 case report describes a 52-year-old man who developed generalized vitiligo two months after stopping finasteride and suggests this may be part of post-finasteride syndrome.

In this study, micronutrient intake was associated with androgen levels in women with PCOS, with the association more pronounced in NA PCOS compared to HA PCOS groups.

This meta-analysis reported a significant association between vitamin D receptor gene ApaI polymorphism and polycystic ovary syndrome risk, with variations observed between Asian and Caucasian populations.

This case report describes the development of halo naevi, vitiligo, and diffuse alopecia areata in a 33-year-old woman undergoing tocilizumab therapy, suggesting a link between these conditions and cellular and humoral immune factors.

In this study, researchers found that the vitamin D receptor plays a crucial role in promoting differentiation and protecting against UVB-induced DNA damage in murine melanocytes, suggesting potential implications for melanoma progression.

This case report documents a female toddler with novel compound heterozygous mutations in the VDR gene causing hereditary 1,25-dihydroxyvitamin D-resistant rickets, expanding the known mutation spectrum for this disease.
