research The Role of Topical Vitamin D in Vitiligo: A Narrative Literature Review
This literature review highlights the effectiveness of topical vitamin D (e.g., calcipotriol, calcitriol) in treating vitiligo, emphasizing its role in melanogenesis and as an immunomodulator, either alone or combined with topical corticosteroids, offering minimal side effects.
research Prevalence of Low Serum Vitamin D Levels in Patients Presenting With Androgenetic Alopecia: A Review

research A novel LC-MS/MS analysis of vitamin D metabolites in mice serum and hair: impact of diet and light exposure
In this study, researchers observed that dietary vitamin D intake and light exposure play a crucial role in vitamin D metabolism in mice, suggesting similar importance for human health in maintaining optimal vitamin D levels.
research Evaluation of serum ferritin, vitamin B12 and vitamin D levels as biochemical markers of chronic telogen effluvium in women
This study found low serum ferritin and vitamin B12 levels in a significant portion of women with chronic telogen effluvium, while vitamin D deficiency was less common.
research Serum Vitamin D levels in males with premature androgenetic alopecia: a prospective case-control study
This study found that men with androgenetic alopecia had significantly lower serum vitamin D levels compared to controls and the deficiency strongly correlated with the severity of the condition.
research Knowledge, Attitude, and Practices Related to Vitamin D, Zinc, and Ferritin Deficiencies and the Associated Risk of Hair Loss in Jazan, Saudi Arabia
In this study conducted in Jazan, Saudi Arabia, most participants were aware of vitamin D, zinc, and ferritin deficiencies and their link to hair loss, but only about a third practiced daily sun exposure and vitamin supplement use, highlighting a need for improved health education.
research Serum vitamin D, ferritin, and TSH in patients with telogen effluvium: a retrospective epidemiological study
In this study, 35.4% of telogen effluvium patients showed ferritin deficiency and 34.2% had vitamin D deficiency, suggesting these should be included in TE screening; TSH testing should be individualized.
research The Role of Vitamin D in Non-Scarring Alopecia
This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.
research Hereditary vitamin D-resistant rickets in Lebanese patients: the p.R391S and p.H397P variants have different phenotypes
This study identified two distinct VDR gene mutations among Lebanese families with hereditary vitamin D-resistant rickets, noting varied treatment responses and promising outcomes despite severe phenotypes.
research Vitamin D metabolism and function in the skin
This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.
research Genetic Disorders and Defects in Vitamin D Action
This article compares two rare genetic diseases, vitamin D-dependent rickets type 1 and type 2, focusing on their similar presentations of hypocalcemia and rickets in infancy, but reports no new clinical results.
research The Vitamin D Receptor Is a Wnt Effector that Controls Hair Follicle Differentiation and Specifies Tumor Type in Adult Epidermis
This study observed that the vitamin D receptor is crucial for hair follicle formation and altering tumor development in the Wnt signaling pathway, suggesting therapeutic potential for vitamin D analogues in related tumors.
research The role of vitamin D receptor mutations in the development of alopecia
Vitamin D receptor mutations can cause alopecia by affecting hair growth genes.
research Mutations in the vitamin D receptor and hereditary vitamin D-resistant rickets
This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.
research An Unusual Form of Vitamin D-Dependent Rickets in a Child: Alopecia and Marked End-Organ Hyposensitivity to Biologically Active Vitamin D
This case study describes a child with an unusual form of vitamin D-dependent rickets, characterized by alopecia and a deficient response to active vitamin D.
research Vitamin D-dependent rickets type II. Defective induction of 25-hydroxyvitamin D3-24-hydroxylase by 1,25-dihydroxyvitamin D3 in cultured skin fibroblasts.
This study found that measuring 24-OHase induction by 1,25(OH)2D3 in cultured skin fibroblasts is a sensitive test for detecting genetic defects in the 1,25(OH)2D effector pathway.
research The Vitamin D Receptor Is Required for Activation of cWnt and Hedgehog Signaling in Keratinocytes
This study found that the absence of unliganded vitamin D receptor significantly impairs cWnt and hedgehog signaling pathways necessary for hair cycle initiation in VDR-null mice.
research The Vitamin D Receptor as Tumor Suppressor in Skin
This study suggests that vitamin D and its receptor may protect against the development of epidermal tumors following UV radiation by regulating specific cellular signaling pathways.
research The hair cycle and Vitamin D receptor
This study found that while calcium can substitute for the Vitamin D receptor in maintaining epidermal keratinocyte differentiation, it cannot compensate for hair follicle dysfunction caused by the absence of the receptor.
research Hereditary 1,25-dihydroxyvitamin D-resistant rickets with alopecia resulting from a novel missense mutation in the DNA-binding domain of the vitamin D receptor
This study identified a novel V26M mutation in the vitamin D receptor as the cause of hereditary vitamin D resistant rickets in a patient, characterized by severe rickets and an unusual pattern of alopecia.
research Reciprocal role of vitamin D receptor on β-catenin regulated keratinocyte proliferation and differentiation
This study found that 1,25-dihydroxyvitamin D3/VDR inhibits β-catenin's role in keratinocyte proliferation but enhances its role in hair follicle differentiation.
research Vitamin D and skin diseases: A review
This review discusses the various roles of vitamin D in skin disorders, including established use in psoriasis and potential applications for atopic dermatitis and skin cancer prevention, but reports no new clinical results.
research Hereditary 1,25‐Dihydroxyvitamin D–Resistant Rickets Due to an Opal Mutation Causing Premature Termination of the Vitamin D Receptor
In this study, researchers identified a unique Arg30stop mutation in the vitamin D receptor gene that causes hereditary vitamin D-resistant rickets in a young French-Canadian boy by truncating the receptor and causing hormone resistance.
research The vitamin D receptor functions as a transcription regulator in the absence of 1,25-dihydroxyvitamin D3
This study found that in a mouse model with hereditary 1,25-dihydroxyvitamin D resistant rickets, a mutant vitamin D receptor lacking hormone-binding ability could restore normal hair cycling and affect parathyroid hormone regulation.
