TLDR Low Vitamin D3 levels are linked to hair loss in female students in South India.

In a case-control study conducted among the student population in South India, researchers found a significant association between Vitamin D3 deficiency and diffuse hair fall. The study included 44 young adults, with 22 participants experiencing hair fall of more than 100 strands a day (cases) and 22 age-matched healthy individuals (controls). The mean age of participants was 20.89 years. Results showed that 81.8% of the cases had Vitamin D deficiency compared to 45.5% of the controls, with a statistically significant difference (P = 0.007). Female students in particular exhibited significantly lower levels of Vitamin D3 in cases compared to controls. The study did not find significant differences in Vitamin D3 levels based on ethnicity or the use of full sleeve clothing, sunscreen lotion, and sun exposure. None of the cases had normal Vitamin D levels, while 4.5% of controls did. The study concluded that there is a significant correlation between low Vitamin D3 levels and diffuse hair fall in female students.

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

in Chat 51 upvotes 1 month 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 As in this research, i have seen many who advise a regular use of VitaminD, even if you are not deficient. Once i had read in tressless that mpb and Vitamin D might have a correlation. So could it be an a benefit to add this to your ongoing treatment plan?

Hair loss may be caused by calcification of capillaries in the scalp, restricting blood flow to hair follicles. A daily treatment regimen including high doses of Vitamins D and K, Magnesium, and Nattokinase could potentially decalcify these capillaries, improving blood flow and hair growth. However, some users warn against excessive Vitamin D intake and emphasize the need for medical consultation.

A user is trying to reverse male pattern baldness (MPB) naturally by taking high doses of Vitamin D, improving diet, exercising, reducing stress, and other lifestyle changes, but plans to use finasteride if no results are seen in 60 days. Other users are skeptical, advising medical treatments like finasteride and warning against potential vitamin D overdose and the ineffectiveness of natural remedies for genetic hair loss.
