In this study, plasmatherapy was found to improve immune status indicators in patients with vitiligo, particularly benefiting those with segmental vitiligo by normalizing immune markers and reducing IL-6 levels, suggesting its potential as an adjunct treatment to slow depigmentation progression.

This case report describes a 33-year-old woman whose symptoms improved significantly after vitamin D and zinc supplementation, highlighting the importance of diagnosing and managing deficiencies to enhance quality of life in young women.

This study found that patients with alopecia, particularly alopecia areata and female pattern hair loss, often have vitamin D deficiency, suggesting that screening for vitamin D could benefit these patients.

This study, conducted among 50 women with female-pattern hair loss, observed that 89% had deficient or insufficient vitamin D levels and also showed low ferritin levels, suggesting these deficiencies may contribute to hair loss.

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 review reports that vitamin D plays an important role in hair follicle development, with a negative correlation observed between serum vitamin D levels and female pattern hair loss, suggesting further research is needed before recommending vitamin D as a treatment.
