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 observed that pregnant women with severe diffuse hair loss during their last two trimesters had notably lower zinc, hemoglobin, PCV, ferritin, and vitamin B12 levels compared to non-pregnant women.

Vitamin B12 deficiency can cause skin darkening and increased blood vessels, but treatment can improve symptoms.

This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

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.

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.

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.

This study investigates differences in nutritional status, vitamin, and mineral levels between individuals with telogen effluvium and a control group, aiming to understand the nutritional factors involved in this condition.

This study examined the demographics of patients diagnosed with pernio and compared their vitamin B12, folate, and ferritin levels with those of a control group.

This report describes a case in which intramuscular cyanocobalamin treatment reversed skin and nail pigmentation changes and premature gray hair caused by vitamin B12 deficiency due to pernicious anemia.

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.

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 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.

This study identifies a specific subtype of Telogen Effluvium associated with scalp dysesthesia, such as itch or burning, in the absence of any inflammatory scalp disorder or medication association.

This study suggests that long-term treatment with valproate, acetylcarnitine, folic acid, and vitamin B12 may benefit children with SMA types II and III by improving muscle strength and function without significant adverse effects.

This study explored how vitamin B12 is essential for hair growth and nervous system health, highlighting that factors causing its malabsorption, like gastric issues and smoking, can lead to optic neuropathy and hair loss.

This study found that while both conventional care and teledermatology showed similar clinical response rates for treating actinic keratosis with imiquimod 5% cream, teledermatology was associated with higher treatment failure and local reaction rates.

This study found that exogenous melatonin improved cashmere fiber quality and yield in goats by enhancing antioxidant capacity and reducing pro-aging cytokine expression in secondary hair follicles.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

In this animal study, AGO (agomelatine) effectively alleviated testosterone-induced benign prostatic hyperplasia in rats by reducing oxidative stress and inflammation, indicating its potential as a therapeutic option for managing BPH through specific signaling pathways.

Vitamin B12, folate, ferritin, and iron levels are not linked to alopecia areata.

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.

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.

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

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 found no significant association between serum levels of vitamin B12, folate, TSH, ferritin, zinc, or anxiety scores and trichodynia in telogen alopecia patients.

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.

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.

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.
