research Serum Vitamin B12, Folate, Ferritin, and Iron Levels in Turkish Patients with Alopecia Areata
Vitamin B12, folate, ferritin, and iron levels are not linked to alopecia areata.
research Reduced Serum Vitamin B12 Levels During Oral Cyproterone Acetate and Ethinyl Estradiol Therapy in Women With Diffuse Androgen-Dependent Alopecia
In this study, women treated for androgen-dependent alopecia with CPA EE2 therapy experienced significant decreases in serum vitamin B12, hemoglobin, and hematocrit levels after six months.
research Counteraction of Cortisone Inhibition of Body, Hair, and Thymus Growth by Vitamin B12 and Aureomycin
In this study of immature male albino rats on a vitamin B12-deficient diet, vitamin B12 supplementation improved body, hair, and thymus growth more effectively than aureomycin when countering the negative effects of cortisone.
research Demographic Characteristics and Association of Serum Vitamin B12, Ferritin, and Thyroid Function with Premature Canities in Indian Patients from an Urban Skin Clinic of North India: A Retrospective Analysis of 71 Cases
This study found that premature hair graying is strongly associated with a family history, Vitamin B12 deficiency, and hypothyroidism, with onset as early as 5 years in patients in Gurugram, India.
research Reversible Cutaneous Hyperpigmentation and Nails with White Hair Due to Vitamin B12 Deficiency
Vitamin B12 deficiency can cause skin darkening and white hair, but it's reversible.
research Skin Hyperpigmentation and Increased Angiogenesis Secondary to Vitamin B12 Deficiency in a Young Vegetarian Woman
Vitamin B12 deficiency can cause skin darkening and increased blood vessels, but treatment can improve symptoms.
research Serum Holotranscobalamin, Vitamin B12, Folic Acid, and Homocysteine Levels in Alopecia Areata Patients
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.
research Beneficial Effects of Vitamin B12 and Aureomycin in Rats Given Large Doses of Cortisone
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.
research Reversible Hyperpigmentation of Skin and Nails With White Hair Due to Vitamin B12 Deficiency
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.
research Developing New Graft Holding Solutions: In Vitro Evaluation of Bioactive Molecules Identifies Vitamin B12 as Micrograft Stabilizing Substance
This abstract reviews recent findings on the biology of isolated micrografts in hair restoration, emphasizing factors that enhance micrograft viability, but it does not report new experimental results.
research Localized Skin Hyperpigmentation as a Presenting Symptom of Vitamin B12 Deficiency Complicating Chronic Atrophic Gastritis
This case report highlights an atypical presentation of vitamin B12 deficiency in a 28-year-old man with reversible symptoms including localized hand hyperpigmentation and megaloblastic anemia, resolved after B12 supplementation.
research Total Melanonychia of 20 Nails as a Rare Manifestation of Vitamin B12 Deficiency
This case report describes a 47-year-old male with rare total melanonychia linked to vitamin B12 deficiency, whose nail discoloration and constitutional symptoms improved following vitamin B12 supplementation.
research Vitamin B12 Activates the Wnt-Pathway in Human Hair Follicle Cells by Induction of Beta-Catenin and Inhibition of Glycogen Synthase Kinase-3 Transcription
This study demonstrated that vitamin B12 may promote hair growth in vitro by modulating intracellular signaling in the wnt-pathway, suggesting potential benefits for micrograft transplantation.
research Reversible Facial Hyperpigmentation Associated With Vitamin B12 Deficiency
This case report describes a rare instance of reversible melasma-like hyperpigmentation linked to vitamin B12 deficiency due to pernicious anemia, and explores possible mechanisms for this association.
research Evaluation of Zinc, Vitamin B12, Folic Acid, and Iron Levels and Thyroid Functions in Patients with Chronic Telogen Effluvium
This study compared serum zinc, vitamin B12, folic acid levels, iron metabolism, and thyroid function between chronic telogen effluvium patients and healthy controls, but it reports no specific clinical results.
research Serum Levels of Ferritin, Vitamin B12, and Folate in Women with Telogen Effluvium Outside of Menopause
Low levels of ferritin and vitamin B12 are common in women with telogen effluvium, but the link between nutrient deficiencies and the condition is not clear.
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 The Association Between the Levels of Ferritin, TSH, Zinc, Hemoglobin, Vitamin B12, Vitamin D and Hair Loss Among Different Age Groups of Women: A Retrospective Study
This study found that reduced levels of ferritin, TSH, and hemoglobin in young women and lower TSH, vitamin B12, and vitamin D in older women are associated with chronic diffuse hair loss.
research Reversible Hypopigmentation of Hair Secondary to Vitamin B12 Deficiency
This case report describes reversible hypopigmentation of hair in a child due to vitamin B12 deficiency, which improved after vitamin B12 supplementation.
