research How coronavirus disease 2019 vaccination affect the level of vitamin D in serum and hair?

January 2025 in “Egyptian Journal of Dermatology and Venerology”

This study found that COVID-19 vaccination initially lowered vitamin D levels in serum and hair but increased serum levels after the second dose, except for the Pfizer group. Hair vitamin D showed a nonsignificant increase, and hair loss was most common with the AstraZeneca vaccine.

research The hair cycle and Vitamin D receptor

50 citations , October 2011 in “Archives of Biochemistry and Biophysics”

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 Serum levels of vitamin D3 in patients with hair loss

July 2016 in “Journal of Dermatology and Cosmetic”

This study found that 66% of patients with hair loss also have vitamin D deficiency, with a significantly higher prevalence among women than men.

research The Vitamin D Receptor Is a Wnt Effector that Controls Hair Follicle Differentiation and Specifies Tumor Type in Adult Epidermis

127 citations , January 2008 in “PloS one”

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 Vitamin D Receptor Is Required for Mouse Hair Cycle Progression but not for Maintenance of the Epidermal Stem Cell Compartment

25 citations , March 2008 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study suggests that while VDR is crucial for maintaining hair follicles in mice, their degeneration may be linked to impaired cell migration during hair growth phases rather than stem cell loss.

community Does vitamin D deficiency actually cause hair loss? Has anyone actually grew back hair after fixing vitamin d levels?

in Chat 65 upvotes 1 year ago

Vitamin D deficiency can contribute to hair loss, but it is not the sole cause, and supplementation may not always resolve the issue. Treatments like finasteride and minoxidil are recommended for hair regrowth, with vitamin D and other supplements providing additional support.

community Vitamin D deficiency and hair loss - does anyone have personal evidence of hair regrowth following correction?

in Research/Science 4 upvotes 4 months ago

Vitamin D deficiency may contribute to hair loss, but correcting it alone doesn't guarantee regrowth. Users report mixed results with supplements and treatments like minoxidil, finasteride, and dutasteride.

community What vitamin deficiencies that cause hair loss

54 upvotes 1 year ago

Vitamin deficiencies, particularly in vitamins A, B, C, D, and minerals like iron, zinc, and copper, can lead to hair loss. Dietary changes, such as eating more nutrient-rich foods, can improve hair health.

4 upvotes 8 years ago

The conversation discusses hair shedding potentially linked to vitamin D supplementation after Accutane use, with the user suspecting telogen effluvium. Others suggest the hair loss might not be related to vitamin D, considering it a coincidence.
